the pronotum and basal parts of the head short and clavate. Read 

 rather large, moderately convex, fully as wide as long, finely but strongly, 

 densely punctate, with the smooth line uneven, truncate and with a deep 

 canaliculiform impression at base, the angles broadly rounded; tempora 

 slightly divergent and feebly arcuate to the eyes, the latter somewhat longer 

 than the temjiora, large and prominent; antenn;e rather longer than the head 

 and prothorax, moderately incrassate, the tenth joint as long as wide. Pro- 

 thorax much narrower than the head, fully as long as wide, rounded at the 

 sides, obtusely constricted at basal fourth, moderately convex, strongly and 

 closely punctate. Elytra two-thirds to three-fourths longer than wide in the 

 female and male respectively, slightly dilated behind the middle in the former, 

 subparallel in the latter and more obtusely rounded at apex ; scutellar impres- 

 sion distinct; omoplates subobsolete; surface strongly, densely and moderately 

 coarsely punctate. Abdomen dull, densely and finely sculptured, smooth and 

 densely punctate near the base. Leys somewhat long and slender. Length 

 3.0-3.25 mm. ; width 0.9-1.05 mm. 



Southern Arizona. 



The male has quite distinct sexual characters, the apex of the 

 fifth ventral being broadly but strongly sinuate in circular arc. 



The four specimens before me are perfectly constant in the 

 pattern of coloration. 



38. A. juiictllS n. sp. — Subparallel, rather depressed, slightly shining, 

 black, the prothorax frequently entirely or partially testaceous; legs pale, the 

 femora sometimes darker; antennae testaceous; elyti'a with a large pale area in 

 basal fourth to third, evidently formed by the union of two large spots, each ely- 

 tron also having a rounded pale spot at apical fourth; pubescence short, nearly 

 as in vulneratu!:!. Head somewhat large, moderately convex, shining, strongly, 

 closely punctate with the smooth line imperfect toward base, the latter trun- 

 cate, impressed at the middle, the angles rounded; eyes rather small, convex, 

 very much shorter than the tempoYa, the latter parallel, then gradually rounded 

 into the base; antennaj fully as long as the head and prothorax, rather strongly 

 incrassate, the tenth joint about as long as wide. Prothorax much narrower 

 than the head, as long as wide, obtusely constricted at basal fourth, somewhat 

 stronglj' rounded and widest at apical fourth, finely but strongly, rather closely 

 punctate. Elytra two-thirds longer tlian wide, twice as wide as the prothorax, 

 slightly Avider behind the middle than at base, the sides feebly arcuate; apex 

 rather broadly rounded; humeri broadly exposed; scutellar impression strong; 

 omoplates scarcely visible; disk somewhat depressed, densely, strongly and 

 rather coarselj' punctate. Abdomen alutaceous, minutely, densely punctate, 

 the legs rather long and slender. Length 3.25-3.5 mm.; width 0.95-1.1 mm. 



New Mexico (Las Vegas); Arizona. 



The male has the fifth ventral much longer than the fourth, 

 rather broadh' truncate at opex, the genital segment small, pale, 

 coriaceous, transversely and evenl}^ convex, with an abrupt, deep
