Coleopterological Notices, VI. Y09 



The copiilatory sheath is long, moderatel}" stout, onh' feebly 

 fircuate from base to apex, parallel-sided and transversely^ convex 

 from a dorsal point of view, gradually narrowed in a long simple 

 ogival and not very acute point in apical third, the under surface 

 deeply excavated throughout, the walls projecting strongly in- 

 ward at basal fifth or sixth. It is thus of the same type as in 

 punctulatus, but is parallel, more pointed and much less arcuate. 



26. A. gileiisis u. sp. — ^Moderately stout, convex, rather dull, rufo-ferru- 

 giuous, the alxlonien blackish; elytra with a feeble and nubilate blackish 

 fascia at the middle and a paler subapical spot as in cen'inus, both frequently 

 obsolete. Head subi^uadrate, wider than long, strongly convex, finely, some- 

 what closely punctate, without a well-defined smooth line, the base truncate 

 and feebly imj)ressed; eyes large and prominent, at a little less than their own 

 length from the base; antennje long and rather stout, decidedly incrassate, as 

 long as the head and prothorax, the tenth joint not quite as long as wide. 

 Prothorax distinctly narrower than the head, fully as long as wide, convex, 

 obtusely constricted at basal fifth, broadly rounded at the sides anteriorly, 

 finely, closely punctate. Elytra three-fourths longer than wide, slightly more 

 than twice as Avide as the prothorax, the sides parallel and feel)ly arcuate; 

 apex not very broadly rounded; punctures somewhat fine but deep and very 

 close-set. Abdomen rather dull, the legs very pale; femora somewhat stout. 

 Length 2.2-2.7 mm. ; width 0.7-0.9 mm. 



Arizona (Tu9son). 



This species is closeh' allied to cervinus, differing in its stouter 

 and more incrassate antennae, broader head which is broadly im- 

 pressed in the middle at base, and in its still larger ej'es. The 

 copulatory sheath is nearl}' similar to that of cervinus, but is 

 more gradually narrowed to an obtuse ogival point in more than 

 apical half; the efferent duct is stout, but becomes rapidl}- and 

 obliquely pointed toward apex. 



27. A. praeceps n. sp. — Moderately stout and convex, shining, black 

 throughout beneath, the head and pronotum picescent; elytra dark rufo-tes- 

 taceous, becoming flavate toward base, aloiig the apical margin and in a 

 rounded spot near apical fourth, the surface blackish before and behind the 

 spot; antennie and legs throughout pale flavate; pubescence cinereous, rather 

 coarse and abundant, somewhat long on the elytra. Head fully as long as 

 wide, parallel, broadly arcuato-truncate and unimpressed at base, the angles 

 rounded; tempora becoming parallel for some distance behind the eyes, the 

 latter moderateh- large, prominent; punctures fine but strong, rather close, 

 the impunctate line feebly defined ; antenna; distinctly shorter than the head and 

 protliorax, somewhat stout, feebly incrassate, the tenth joint scarcely as long, 

 as wide. Prothorax small, much narrower than the head, a little longer than
