Coleopterological Notices, VI. *r09 



The copnlatory sheath is long, moderately stout, only feebly 

 arcuate from base to apex, parallel-sided and transversel}^ 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. ^ileiisis n. sp. — Moderately stout, convex, rather dull, rufo-ferru- 

 ginous, the abdomen blackish; elytra with a feeble and nubilate blackish 

 fascia at the middle and a paler subapical spot as in cervinus, both frequently 

 obsolete. Head sub(iuadrate, wider than long, strongly convex, finely, some- 

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

 and feebly impressed; eyes large and prominent, at a little less than their own 

 length from the base; antennaj long and rather stout, decidedly incrassiite, 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 wide as the prothorax, the sides parallel and feebly 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 (Tucson). 



This species is closel}^ allied to cert'^nMS, 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 eyes. The 

 copulatory sheath is nearly 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 rapidly and 

 obliquely pointed toward apex. 



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

 tlu'oughout beneath, the head and pronotum picescent; elytra dark rufo-tes- 

 tiiceous, becoming flavate toward base, along the apical margin and in a 

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

 spot; antenna; 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 moderately large, prominent; punctures fine but strong, rather close, 

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

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

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