THE CANADIAN ENTOMOLOGIST l4l the elytral intervals in the latter is sometimes ver\ line and a good magnifica-tion is necessary. 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.

A. canadensis, sp. nov. NEW OR LITTLE-KNOWN CRANE-FLIES FROM TROPICAL AMERICA (TIPULID^, DIPTERA). BY CHARLES P. ALEXANDER, Urbana, III. 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
