Goleopterological Notices, VI I. 3t3 



feebly porrect and short ; surface between the antennal cavities on the sub- 

 vertical part of the front convex and tumid. Antennae rather stout, not quite 

 3^ as long as the body, the club strong and abruptly differentiated ; second 

 joint as long and about as wide as the first but strongly obconic, twice as long 

 as wide, as long as the next two and noticeably thicker ; three to six subequal, 

 oval, the third and fifth rather longer, the fourth and sixth somewhat shorter, 

 than wide ; seventh J4 vsdder, roughly sculptured apically, subquadrate ; 

 eighth fully }4 wider, conic in apical ^5, about as long as wide ; ninth and 

 tenth similar to the eighth but a little wider, the former not quite as long as 

 wide, the latter distinctly wider than long ; eleventh a little stouter, very 

 obtusely ogival at apex, a little shorter than the two j)receding. Prothorax as 

 long as wide, scarcely ^5 wider than the head, the sides parallel and broadly 

 sinuate posteriorly, rounded anteriorly ; apex truncate and % as wide as the 

 base ; surface bifoveate at each side near the base but not distinctly impressed, 

 the outer fovea much the smaller, also minutely excavated near each flank at 

 the basal margin. Elytra rather long, 1^ longer than wide, much more than 

 twice as long as the prothorax and about % wider, widest near basal ^5, the 

 sides moderately rounded ; apex narrow ; humeral plica and adjoining im- 

 pression rather small, feeble ; basal fovese small but deep, perforate and ap- 

 proximate ; at some distance from the base there is a very feeble impression 

 on the suture, the latter not at all beaded basally. Legs well developed ; two 

 anterior femora strongly, the four posterior rather feebly, clavate ; hind tarsi 

 with the first four joints subequal, the first scarcely as long as the second. 

 Length 1.6 mm. ; width 0.55 mm. 



Iowa (Iowa City) ; District of Columbia. 



No marks indicative of sex can be discovered in the two speci- 

 mens before me, but in the eastern specimen the two penultimate 

 antennal joints are more transverse, and the seventh joint is per- 

 fectly similar to the sixth and just visibly larger. This species 

 is said to occur with ants, 



8. E. nigrescens n. sp. — Eather narrow and feebly ventricose, black 

 throughout, the abdomen pale at apex ; legs and antennse testaceous ; integu- 

 ments polished, the elytra feebly but distinctly punctate; pubescence abun- 

 dant, pale and coarse, long, stiff and densely bristling posteriorly on the occi- 

 put, especially at the sides, bristling on the pronotum, unusually short, even 

 and closely recurved on the elytra, where the sparse erect hairs are quite 

 short and inconspicuous. Head not quite as long as wide, semicircular ly 

 rounded behind the eyes, which are rather small, anterior and but slightly 

 prominent ; antennal tubercles small, feeble and distant, the front not concave, 

 the cavities very large and narrowly separated on the declivous front; clypeus 

 simple, rectilinearly truncate. Antennse short and somewhat stout, barely as 

 long as the head and prothorax, the club strong and very abrupt; second joint 

 as long as the first and somewhat narrower, very feebly obconical, % longer 

 than wide, fully as long as the next two and distinctly thicker; three to five 

 equal and very slightly wider than long, the sixth scarcely perceptibly wider
