Judging by their descriptions* there is little to choose be- tween these two species except their different habits. Greater differences might be noted if the descriptions of both species were not so abbreviated. Bibliography of Group I-b. Aphodius rubeoliis Beauv., Ins. Afr. et Amer., 1805, 90.

The majority of the new species described herein as new were secured by Mr. Herbert S. Parish along the Amazon River. The new Teucholabis was secured by Prof. Hine in Guatemala, and sent to me through the kindness of Dr. Kennedy. The new species are preserved in the collection of the author. Teucholabis pabulatoria, sp. n. Size very small (wing under 4 mm.); head gray; general coloration reddish \'ellow: pleura with an appressed gray pubescence; wings hyaline, the stigma small and ill-defined; Sc\ ending just beyond the origin of Rs; R2+3 in alignment with Rs: cell Rz very wnde at the wing-margin. Male. — Length 3.6 mm.; wing 3.5 mm. Female. — Length 3.8 mm.; wing 3.7 mm. Rostrum reddish brown; palpi dark brown. Antennae with the scapal segments dark brown, sparsely pruinose; flagellum broken. Head light gray. Pronotum reddish yellow. Mesonotum reddish brown, the praescutum without distinct stripes. Pleura reddish yellow, the ventral sclerites with a heavy, grayish white pubescence. Halteres light brown, the large knobs dark brown. Legs with the coxae reddish, sparsely pruinose; trochanters dull yellow; femora yellow, the tips broadly dark brownish black; tibiae brownish yellow, the tips narrowly dark brown; metatarsi light brown, the apical third blackened; remainder of the tarsi black. Wings hyaline, the stigma barely indicated, brown; veins dark brown. The microscopic trichiae on the wing-disk are here larger than is usual in the genus. \^enation: Sc short, Sci ending a short dis- tance beyond the origin of Rs, Sc2 a short distance from the tip of Sci, located before the origin of the sector; Ri beyond r very short, the tip pale; Rs long, gently arcuated, in alignment with and subequal to R2+3; r in alignment with the deflection of i?4+5; cell Rz very wide at the wing-margin ; i?4+5 bending strongly to the wing-tip; inner end of cell 1st M2. lying a short distance proximad of the inner ends of cells Rz and Rw basal deflection of iVfi+2 and the outer deflection of Mz almost obliterated; basal deflection of Cm a short distance beyond the fork of M. Abdomen brown, the sternites paler. Male hypopygium with the pleurites June, 1920 142 THE CANADIAN ENTOMOLOGIST short, the tips projecting far beyond the very simple chitinized, pleural appen- dages which are situated on the inner face; these appendages are two in number, one appearing as a slender, cylindrical, chitinized arm, the other appendage appears as a flattened plate which runs out into a small, chitinized point. From the hypopygium projects a long, slender rod, pale, the tip enlarged and slightly blackened. The homologies of this rod cannot be told from the material at hand. Habitat. — Guatemala. Holotype. — d^, Gualan, January 13, 1905, (J. S. Hine). Allotype. — 9. The types were taken from the mouth of a female damsel-fly {Helcerina tricolor Burm.) Ijy Dr. C. H. Kennedy. By the writer's key to the American species of Teucholahis (Trans. Amer. Ent. Soc, \^ol. 40, pp. 235-239: 1914), Teucholabis pahulatoria will run to T. jocosa Alexander from which it is readily told by its small size, the very different coloration of the thorax, and the \'enation. Erioptera (Mesocyphona) cladophora, sp. n. Generally similar to E. anntilipes Williston; tibia^ with four brown bands; 2nd Anal vein strongly sinuous and with a spur before its tip. Male. — Length 2.8 mm.; wing 2.8 mm. Female. — Length 3.5 mm.; wing 3.5-3.6 mm. Generally similar to E. anniilipes, differing as follows: Most of the femora with four brown bands; tibiae with four narrow brown bands, alternating with four subequal white areas; metatarsi with the base and apex dark brown; tarsal segments three to five and the end of the second dark brown. Wings with a faint brownish tinge; large whitish subhyaline areas occupy the ends of all the cells along the wing-margin; similar white areas in the ends of cells R and M and before the large spur of the 2nd Anal \'ein in cell Lst A; small brown spots at the ends of all the longitudinal veins; a narrow, dark brown seam along the cord; veins dark brown. \'enation: Generally as in E. annulipes but the 2nd Anal vein is very remarkably distinct; very strongly bisinuous, almost as in the genera Helobia and Symplectomorpha, before the last curve with a strong spur that juts into cell 1st A, this spur directed cephalad and basad, in some specimens almost attaining vein 1st A and thus appearing as a supernumerary cross-vein in cell 1st A (as in the genus Discobola) ; this spur is surrounded by a dark seam. Male hypopygium with two long, slender pleural appendages, the outermost bifid almost to the base and thus appearing as two separate appendages; inner appendage longest and more strongh- cur\ed than in the others; gonapophyses appearing as a long, slender, slightly-incurved rod with the apex blackened. ^.

THE CANADIAN ENTOMOLOGIST 14H The female sex of this beautiful crane-fly has never been described. One specimen was taken at Flores, Brazil, November 12, 1919, by Mr, H. S. Parish and may be described as allotypic. Allotype. — 9 , length 11.5 mm.; wing 11.8 mm. Rostrum and palpi very small, dark brown. Front obscure yellow. Antennre black, the flagellar segments subcylindrical, feebly constricted beyond mid-length. Head moderately large, the vertex very narrow between the eyes and here with a sparse gray bloom ; remainder of the head dark brownish black. Thorax shiny black, the dorso-pleural membranes obscure yellow. Legs with the coxa? shiny black, the fore coxa? rufous apically; trochanters rufous; femora rufous, narrowly blackened basally and with the tips broadl>' black; tibiae black, the bases a little paler; tarsi brownish black. Wings as in the male; cell 1st Mi open by the atrophy of the outer deflection of M-i. Abdomen reddish, the seventh and succeeding segments black. Ovi- positor with the tergal valves rather short and slender arising from a long basal shield, the apex dilated into a compressed tridentate blade, the ventral tooth larger and more flattened ; from near the base of the tergal valves on the outer side, a pencil of long, curved, yellow bristles that are directed caudad and laterad ; sternal valves of the ovipositor longer than the tergal valves, originating op^ posite the base of the dorsal shield, the tips acute. Subgenus Polymerodcs, subg. n. Characters as in Polymera, s.s., but the tibial spurs lacking. \'enation reduced, cell Mi lacking and cell Mg small, not longer than its petiole. Type of the subgenus. — Polymera (Polymerodes) parishi, sp. n. This new group is necessitated for the reception of three small species of Polymera in which the tibial spurs are quite lacking. In the typical subgenus, the tibial spurs are long and visible even with a hand-lens. It is very difficult to classify such forms since the females invariably run out to the genus Eriopiera by means of the existing keys. The males have the beautiful bi-nodose antenna^ of the typical subgenus. The species, besides the type, that are referable to this subgenus are P. conjuncta Alexander and P. conjunctoides Alexander. The three known species may be separated by means of the appended key: 1. .Size larger (wing of the male 4 mm. or over); antenna* conspicuously annulated, the base and apex of each flagellar segment light \ellow, the remainder of the segment black; thoracic pleura with a very broad. black stripe that almost covers the entire region parishi, sp. n. Size small fwing of the male less than 4 mm.); antenna' uniformly black; pleura uniformly pale or with a narrow dark stripe 2. 2. Thoracic pleura with a narrow but distinct black longitudinal stripe conjunctoides Alexander. Thoracic pleura without a distinct dark stripe, the pleura being approxi- mately concf)lorous with the dorsum conjuncta Alexander. Polymera (Polymerodes ) parishi, sp. n. Flagellar segments black, annulated with yellow; thoracic pleura largely black. . 144 THE CANADIAN ENTOMOLOGIST Male. — Length about 4 mm.; wing 4-4.5 mm. Generally similar to P. conjuncta Alexander, differing as follows: Size larger. Antennal flagellum with the individual segments distinctly annulated, black with the base narrowly, the apex more broadly, light yellow; each flagellar segment is binodose, the nodes with very long, outspreading verticils. The thoracic pleura has a very broad, brownish black stripe that extends to the abdomen; thoracic sternum also brownish black, the space be- tween this and the pleura only slightly paler. Wings with a strong brown tinge; vein Sc shorter; R^+z shorter than that section of Ri beyond r. Abdomen black. Habitat. — Brazil. Holotype.— d', Manaos, November 4, 1919, (H. S. Parish). Paratopoiype. — A badly-broken d^, October 31, 1919. Eriocera amazonicola, sp. n. General coloration orange-yellow; antennal flagellum brownish black, the scutal lobes and posterior half of the mesonotal prsescutum brownish; wings yellow, narrowly cross-banded and longitudinally streaked with brown, this including a narrow apical margin. Male. — Wing 9.3 mm. Female.- — Length 12 mm.; wing 10.8 mm. Frontal prolongation of the head reddish brown; palpi obscure brownish yellow. Antenna? with the scape fiery orange; flagellum dark brownish black, only the extreme base of the first flagellar segment brighter. Head fiery orange, the frontal tubercle moderately large and with a slight, impressed, median line. Mesonotum obscure yellow, the prsescutum behind and the scutal lobes more brownish; scutellum and postnotum more orange-yellow. Pleura yellow. Halteres yellow, the knobs dark brown. Legs with the coxae and trochanters yellow; femora obscure yellow, the tips narrowly dark brown; tibiae obscure brownish testaceous, the tips very narrowly darker brown; tarsi dark brown. Wings with a strong yellowish tinge, most conspicuous in the costal region and at the wing-base; anal cells more grayish; conspicuous brown seams at the origin of Rs, extending to beyond midlength of the vein; along the cord, extending as a narrow cross-band from the stigma to the posterior margin of the wing; a narrow seam around the wing-tip; veins -R4+5, Mz, Cu\, the outer end of cell 1st M2, Cu and 2nd A narrowly margined with brown; veins light yellow, darkened in the brown areas. Venation: Rs long; r just beyond the fork of R»+z; inner ends of cells R^ and 1st M-i in oblique alignment; cell 1st Mo rather small, sub- rectangular, shorter than the veins beyond it; basal deflection of Cui just beyond the fork of M. Abdomen with the tergites fiery orange, segments five and six darker basally ; sternites orange-yellow. Ovipositor with the vahes elongate, chitinized. Habitat. — Brazil. HoIotype.— 9 , Manaos, November 4, 1919, (H. S. Parish). Allotype.— d", Flores, November 12, 1919. The male specimen is in poor condition, having been badly eaten by ants. The hypopygium is of the Eriocera-type but the penis-guard is very long and exserted, somewhat as in E. longistyla Alexander.
