40G Coleopterological Notices. 



A. allltacea n. sp. — Body black throughout, smooth, dull, parallel, 

 lately convex; elytra rather depressed toward the suture; legs dark 

 rufous ; antennae piteous. Head nearly as long as wide, flattened above, the 

 sides before the eyes convergent and broadly reflexed ; surface finely, rather 

 sparsely punctate, the punctures coarser toward the eyes ; epistoma very 

 feebly, longitudinally convex ; antenna? slightly longer than the prothorax, 

 moderately robust but strongly incrassate toward tip. Prothorax always fully 

 as long as, and sometimes slightly longer than wide ; apex and base subequal, 

 the former truncate, the latter broadly, feebly emarginate, the basal angles 

 acute and prominent posteriorly ; sides distinctly convergent behind in basal 

 two-thirds and feebly arcuate ; disk extremely minutely but rather densely 

 punctate. Elytra about twice as long as the prothorax and, near the middle, 

 just perceptibly wider ; humeri finely but acutely dentate, the basal margin 

 being strongly tumid throughout, sides feebly arcuate, disk with almost com- 

 pletely unimpressed rows of coarse perforate punctures, the latter generally 

 separated by fully twice their own diameters ; "intervals flat, the first and third 

 slightly elevated near the apex, extremely minutely and rather sparsely punc- 

 tate. Legs very robust. Length 12.5-15.0 mm. ; width 4.0-5.0 mm. 



Arizona. Mr. Morrison. 



The first ventral segment is strongly and transversely tuberculate 

 in the middle in the male. This species is larger, blacker, duller 

 and more densely punctate than bicolor. 



A. llitida n. sp. — Subparallel, moderately convex, polished, dark rufo- 

 castaneous, the legs and antennae nearly concolorous. Head finely, very 

 densely punctate throughout, the sides broadly reflexed ; epistoma extremely 

 feebly, transversely convex ; antenna? short, scarcely longer than the protho- 

 rax, moderately robust, incrassate toward apex. Prothorax as wide as long : 

 apex truncate ; base feebly emarginate, the basal angles slightly prominent 

 posteriorly ; sides broadly arcuate, more convergent and gradually very feebly 

 sinuate toward the basal angles ; disk very minutely, rather sparsely punctate, 

 the punctures a little larger and denser toward the sides. Elytra elongate- 

 oval, gradually narrowed behind and rather strongly rounded at apex, dis- 

 tinctly more than twice as long as the prothorax and scarcely perceptibly wider ; 

 sides very distinctly arcuate; humeri finely denticulate; disk with feebly 

 impressed rows of very coarse, deep, perforate punctures; intervals flat, the 

 first and third strongly elevated near the apex, extremely minutely, rather 

 sparsely punctate throughout. Legs rather slender. Middle of the first ven- 

 tral segment tuberculate in the male. Length 11.5 mm. ; width 3.7 mm. 



Texas (probably near El Paso). Mr. Gr. W. Dunn. 



The single specimen represents a species resembling bicolor' some- 

 what in general habitus, but differing in its longer and much more 

 densely punctate head, more convex elytra! intervals near the apex 

 and several other characters.
