Elytra more than three times as long as the prothorax, having rows of moderate 

 crescentiform punctures which, at tlie sides, become very strongly transverse, 

 sometimes confluent, and more or less confused in arrangement ; intervals 

 toward the suture each with a row of similar punctures, but about one-half as 

 wide ; discal stria distinct, obsolete at basal third ; surface rather coarsely 

 strigilate in wavy transverse rows throughout. Abdomen nearly as in culca- 

 ratus. Legs moderate. Length 1.8 mm.

This species is closely related to calcaratus, but differs in its 

 much more elongate, slightly less convex form. It is described 

 from the female, and the posterior tibial spurs are rather less de- 

 veloped and less unequal than in the corresponding sex of calca- 

 ratus; the tarsi are nearly similar in structure. In calcaratus the 

 apex of the prosternal process has, without exception, only two 

 terminal setas, while in the present species there is a row of four or 

 five which are longer, and nearly twice as stout ; this constitutes 

 one of the most decisive points of difference between these species. 

 The head is so far retracted within the prothorax in the type as to 

 be invisible from above. 



A. ergoti n. sp. (Walsh MS.) — Strongly convex, almost evenly elliptical, 

 one-half to two-thirds longer than wide, the male slightly the shorter, black 

 above, pale flavo-testaceous throughout beneath ; lustre strongly shining. Head 

 very minutely, sparsely punctate, polished, not reticulate ; eyes rather large ; 

 antennffi nearly as in calcaratus, but with the outer joints rather more robust, 

 and the club more strongly narrowed from apex to base. Prothorax polished 

 throughout, toward base excessively obsoletely transversely strigilate in wavy 

 lines, the punctures extremely minute and sparse ; basal lobe and beaded 

 margin distinct, the latter not extending laterally further than the lobe. Scu- 

 tellum equilatero-triangular, with the sides very feebly arcuate. Elytra sub- 

 alutaceous, very minutely, transversely strigilate in wavy lines, having rows 

 of punctures which, toward the suture, are very minute and feeble, and toward 

 the sides slightly larger, always transversely crescentiform ; discal stria dis- 

 tinct, obsolete at basal two-fifths. Abdomen coarsely reticulate, moderately 

 shining, coarsely, sparsely pubescent. Legs moderate ; posterior tibiffi increas- 

 ing very rapidly in width from base to apex, very obliquely truncate ; spurs 

 nearly as in calcaratus; tarsi very long and slender, three-fourths as long as 

 the tibiae, with the second joint between three and four times as long as the 

 basal, and spongiose throughout beneath, except at the immediate base. 

 Length 1.8-2.2 mm.

The description is drawn from one of the lowan males ; the 

 female is larger, rather more convex, and has the posterior tibiae
