554 Coleopterological Notices, VII. 



very small, lateral large, the connecting sulcus very fine but with a large deep 

 and posteriorly sinuous median portion. Elytra quadrate, % longer than the 

 prothorax and nearly ^^ wider, parallel and broadly arcuate at the sides ; sur- 

 face convex, the discal stria extending not quite to the middle. Abdomen 

 longer and only very slightly narrower than the elytra, the sides parallel and 

 feebly arcuate ; dorsals equal in length, the first two impressed at the middle of 

 the base but not carinate. Length 1.5 mm. ; width 0.45 mm. 



District of Columbia. 



The single female, representing this species, was formerly re- 

 garded by me as the female of congener ; it cannot have that 

 status, however, as the abdominal carinse are well developed in 

 congener and the pubescence much denser ; it may be placed near 

 congener for the present. 



The measurement of congener^ previously given, is a little too 

 great, the male type being about 1.35 X 0.4 mm. in size. 



EUPI^ECTUS Leach. 



The following species may be placed near conjiuens for the 

 present, differing in the structure of the pronotum. 



E, disjunctus n. sp. — Linear, parallel and depressed, polished and 

 bright rufo-testaceous throughout, the pubescence subdecumbent, coarse, mod- 

 erate in length and rather abundant. Head large, much wider than the pro- 

 thorax and wider than long, the eyes rather well developed and convex, at 

 their own length from the base, the tempora circularly rounded behind them 

 to the neck, which is distinctly less than J^ the maximum width ; surface im- 

 pnnctate along the middle, sparsely punctured toward the sides, with two 

 small and nude fovese just behind the middle, separated by the eye-distance 

 of either, and connected by a groove in the form of a horse-shoe ; antennae not 

 as long as the head and prothorax, the three outer Joints gradually wider, the 

 last rather longer than the three preceding. Prothorax relatively rather small, 

 feebly convex, subimpunctate, only 34 wider than long, widest and rather 

 narrowly rounded at apical third, the sides thence gradually convergent to the 

 base and feebly bisinuate ; apex more than }4. ^^^ maximum width, and fully 

 %. as wide as the base ; discal pit narrow and elongate, tending to coalesce 

 with the median subbasal pit, which is moderate in size, but rounded and not 

 joined to the well developed lateral fovese by a visible transverse sulcus. 

 Elytra as long as wide, not quite as long as the head and prothorax, distinctly 

 wider than the head, the sides subparallel and broadly arcuate ; discal stria 

 very short, attenuate, extending to about basal third. Abdomen parallel and 

 straight at the sides, slightly longer and narrower than the elytra, the first 

 three dorsals equal, the fourth much longer ; first two each with two short 

 feeble and divergent basal carinse, separated by less than % the total width ; 

 border well developed, flat and inclined. Legs short and stout ; third joint of 

 the hind tarsi about as long as the second, the claw well developed. Length 

 1.38 mm. : width 0.4 mm.
