sid es from base to apex, the apex moderately broadly rounded ; humeri widely 

 exposed ; omoplates subobsolete ; punctures very coarse and sparse. Abdomen 

 polished, sparsely punctate, the legs slender. Length 2.2-2.4 mm.; width 

 0.75-0.8 mm. 



New York (Willets Point, Long Island). 



A mucli smaller species than ep/l^pp^«m Laf., and distinguishable 

 from scahriceps, to which it is closely allied, by its shorter, more 

 oval elytra, longer and more erect elytral vestiture, sparser cephalic 

 sculpture and several other characters. It seems to be rare and 

 rather local. Five specimens. 



The copulatory sheath is as simple as possible, consisting of a 

 straight paralled-sided fillet, transversely convex above through- 

 out and not at all impressed at the sides toward apex, the latter 

 arcuately narrowed in a perfect ogive, with well defined angulate 

 but unmodified tip; the under surface of the organ is deepl}^ ex- 

 cavated throughout its entire length for the eftei'ent duct. 



12. A. nigrita Mann.— Bull. Soc. Imp. Nat. Mosc, 1853, p. 269. 



Body black throughout. Head and prothorax finely, extremely 

 densely punctate and opaque, the punctures subconfluent ; eyes 

 rather small, at a little more than their own length from the base ; 

 antennae somewhat thick, a little longer than the head and pro- 

 thorax, the intermediate joints but slightly longer than wide, the 

 tenth a little wider than long. Prothorax very slightly narrower 

 than the head, not quite as long as wide, evenly convex. Elytra 

 throughout as in biguttulus, but entirely black. Length 3.2 mm.; 

 width 1.25 mm. 



Alaska (Kenai). The above outline notes were taken from the 

 single specimen in the LeConte cabinet. 



13. A. OTicollis n. sp. — Stout, convex, somewhat shining, brownish- 

 testaceous throughout above and beneath, the head piceous-black ; pubescence 

 abundant, moderate and uniform in length, semi-erect, dusky-cinereous in 

 color. Head subquadrate, as wide as long, transverse, feebly arcuate and un- 

 impressed at base, the angles broadly rounded, the tempora large, becoming 

 gradually parallel near the eyes, the latter moderately large and prominent; 

 surface finely, rather closely punctate, the impunctate line only visible toward 

 base; antennse about as long as the head and prothorax, somewhat stout, dis- 

 tinctly incrassate, the tenth joint distinctly longer than wide. Proihorax 

 rather distinctly narrower than the head, a little longer than wide, strongly, 

 evenly convex, broadly rounded at the sides, the latter gradually convergent 

 and arcuate anteriorly to the somewhat narrow collar, feeblj' convergent in 

 ba sal third to the moderately wide and distinct basal margin, which is feebly
