of structure. The male has the fifth ventral much longer than 

 the fourth. 



17. A. SOlidtlS n. sp. — Stout, convex, shining, rufo-ferruginoiis, the head 

 and elytra darker andpiceous; antennae fuscous, paler toward base; pubes- 

 cence moderately long, coarse, abundant and distinct. Head subquadrate, 

 slightly wider than long, convex, the outline nearly as in biguttulus, the 

 punctures coarse and sparse ; median iminmctate line slightly evident anteri- 

 orly ; eyes moderate; antenna} barely as long as the head and prothorax, some- 

 what incrassate, the tenth joint distinctly longer than wide. Prothorax large, 

 convex, fully as wide as the head, a little longer than wide, widest and 

 broadly rounded at apical third, the sides thence moderately and arcuately 

 convergent to the basal margin which is slightly tumid laterally; punctures 

 coarse deep and close but distinctly separated. Elytra large, two-thirds longer 

 than wide, twice as wide as the prothorax, the sides parallel and arcuate; 

 apex broadly rounded; disk distinctly wider in the middle than at base; hu- 

 meri widely exposed, becoming transverse at the prothorax ; omoplates obso- 

 lete ; punctures coarse and separated by rather more than their own diameters, 

 smaller toward apex. Abdomen finely, closely punctate, the punctures vary- 

 ing slightly in size. Legs rather long, the femora somewhat stout. Length 

 3.7 mm. ; width 1.25 mm. 



Arizona ^Benson). Mr. G. W. Dunn. 



The single female represents a species allied rather closely to 

 biguttulus, but departing structurally in its stouter thicker body, 

 and much coarser and sparser punctuation of the head and pro- 

 notum. 



There is before me another female, taken by Mr. Dunn at El 

 Paso, Texas, which I refer for the present to this species, 

 although it differs to a great degree in color; it is black through- 

 out, the legs paler, the pronotum paler in basal half, the elytra 

 testaceous, with the basal margin, a large uneven median and 

 smaller subapical fascia, black, the last two enclosing the usual 

 pale spot, which is not at all suggested in the type of solidus ; 

 the prothorax, also, is noticeably shorter, being not longer than 

 wide. 



18. A. SllbcalTUS n. sp. — Stout, convex, polished, intense black 

 throughout, the tibiai and antennaa toward base dark piceo-rufous; tarsi testa- 

 ceous; pubescence of the bead and prothorax moderate in length, rather sparse 

 and coarse, the elytra completely devoid of pubescence, each puncture having 

 at the bottom an extremely short seta, not appearing above its margin. Head 

 subquadrate, a little wider than long, convex, similar in outline to that of 

 biguttulus, the punctures somewhat coarse and distant, without an impunctate 

 line; antennae distinctly longer than the head and prothorax, gradually and
