494 Mr. G. A. Boulenger on a neio SnuJce. edging, but the lines on the under surface of the interfemoral white. Ears fairly long, their anterior edge evenly convex, their posterior deeply emarginate. Skull and teeth of normal proportions, the canines scarcely visible from above. Small upper premolars subequal in transverse area, the posterior about half the height of the anterior, very slightly drawn inwards, and clearly visible from without. Dimensions of the type : — Forearm 39 millira. Head and body 44; tail 41; ear 14; third metacarpal 35; lower leg 17; hind foot (s. u.) 7*5. Skull : front of canine to back of ??i' 5" 5 ; greatest length (in another specimen) 14' 5. Nab. Tucuman. Other specimens from Salta (i5/;e^a^2j'«i) and Bolivia (Simons). Type. Female. B.M. no. 0. 7. 9. 4. Collected 7th April, 1899, by L. Dinelli ; presented by Oldfield Thomas. Five specimens examined from the type locality. It would thus appear that in Paraguay and the neighbiuriug parts of Argentina four species of Myotis are to be found, distinguishable as follows : — Greueral colour dark greyish or blackish. Lower belly not -whiter. No naked patch be- tween shoulders M. nigricans, Wied. Lower belly passing into white. A naked patch between shoulders M. albescens, Geoff. General colour more or less rufous or fawn. Lower belly passim^- into yellow. Dorsal fur short, reddish throughout M. ruber, Geoff. Lower belly not yellow. Dorsal fur long, dark at base M.

Eye rather small, its diameter nearly equalling its distance from the mouth. Rostral as deep as broad? (end of snout damaged in the single specimen) ; frontal small, once and a half as long as broad, not longer than the praifrontals, much narrower than the supraoculars^ half as long as the parietals ; On new Eastern Ileterocera. 495 posterior nasal in contact vvitli the single pra30cular ; two post- oculars ; temporals 2 + 2, first lower very large and wedged in between the fifth and sixth labials ; six upper labials, third and fourth entering the eye, third, fourth, and fiftii equal in depth. Scales in 25 rows on the neck, in 19 on the body, Vontrals 223; anal divided; subcaudals GO, mostly single, only the 9 last divided. Dark brown above, with irregular yellowish blotches ; a yellowish vertebral streak on the nape ; sides and lower parts yellowish. Total length 450 millim. ; tail Q5. A young specimen from Queensland, locality unknown, for which I am indebted to my friend Prof. R. Collett. This species differs from P. papuanus, Ptrs. & D^r., to which it is most nearly related, in the narrower frontal shield, the equal de])th of the third, fourth, and fifth labials, and the small number of divided subcaudals. LXTX. — New Eastern Ileterocera. By Colonel C. Swinhoe, M.A., F.L.S., &c. Family Agaristidre. Eusemia solicita^ nov. $. Antenna?, palpi, head, thorax, and fore wings black, palpi with a wdiite band on first and third joints; face with a white spot on each side in front, a white spot between the antennse, and four white spots on the front of thorax ; abdo- men ochreous yellow, with black segmental bands, which are broadest above : fore wings with two ochrcous-white trans- verse bands — the first from the subcostal vein across the middle of the cell, extending downwards nearly to vein 1, the second across the disk from near the costa one third from apex to near outer margin above the hinder angle; also from two to four subapical white dots j in the nine examples before me these bands vary more or less, some being nearly even and some sinuated : the hind wing is reddish orange, with black basal, costal, and outer marginal bands, the outer band attenuated towards the anal angle and its inner margin sinuous; in the middle of the costa there is a knob-shaped production inwards ; a short thick black band from the abdo- minal margin, above the angle, connected by two black lines with the marginal band, two white dots on the apical portion of the marginal black band, sometimes three, sometimes none at all.
