PHALACRIDJE 37 



head minutely punctate, well developed; prothorax still more mi- 

 nutely and sparsely punctate, slightly more than twice as wide as 

 long, with rounded converging sides and the usual medio-basal flat 

 bead; elytra finely, sparsely punctate, almost punctureless through- 

 out basally, the intermediate series posteriorly less distinct than the 

 regular series; sutural stria fine, continuing along the scutellum 

 and base to the sides, the discal stria coarse posteriorly, abbreviated 

 and finer basally; under surface sparsely punctate, the hairs obscure; 

 metasternal process broad, moderately rounded and strongly 

 beaded at apex, not extending beyond the coxae. Length 2.4 mm.; 

 width 1.5 mm. North Carolina vernicatus n. sp. 



5 Body evenly elliptic, small in size, the head relatively smaller, much 

 less than half as wide as the prothorax, polished; under surface 

 piceous, the legs obscure rufous; antennae slender, obscure rufous, 

 the club as long as the funicle, which is of the usual structure; eyes 

 very moderate; head and prothorax very minutely, sparsely punctu- 

 late; elytra short, barely at all longer than wide, very obtuse at tip, 

 the punctures all very small, sparse, those of the intermediate series 

 extremely minute; the punctures postero-laterad become slightly 

 lunate, though very feeble, and in no sense of the very broadly 

 lunate form characterizing simplex and allied species; bead-stria of 

 the suture extremely fine and close but entire as in the preceding, the 

 discal stria very fine, basally abbreviated as usual; beading of the 

 metasternal lobe very fine. Length 1.6 mm.; width 0.8-0.9 mm. 

 New Mexico (Coolidge) sayi Csy. 



Body larger, the head relatively much larger, half as wide as the pro- 

 thorax or very nearly 6 



6 Form very broad, oblong-oval, not narrowed posteriorly, the apex 

 very obtusely arcuate in both sexes; under surface, legs and antennae 

 black or nearly so throughout, the antennae slender, with the third 

 joint unusually long, exceeding the next two combined, the club 

 not quite as long as the funicle, the last joint with a transversely 

 oblique pseudo-suture just beyond the middle and not extending 

 entirely across; punctures of the head and prothorax extremely 

 fine and sparse, the sides of the latter strongly rounded; elytra not 

 longer than wide, with fine discal stria, the punctures of the series 

 fine, becoming very slightly lunate postero-laterad, the intermediate 

 series still finer and feebler; legs broad; abdominal punctures rather 

 strong, subasperate as usual and bearing stiff palish hairs; meta- 

 sternal process very broad, extremely finely beaded. Length 1.9-3.0 

 mm.; width 1.3-2.0 mm. Colorado (Boulder Co.), New Mexico 

 (Coolidge) and Arizona (Walnut and Grand Canon of the Colorado). 



penicillatus Say 



Form less broad, though similarly very convex and perceptibly narrowed 

 behind about the middle, somewhat as in ovalis, the combined apex 

 only moderately broadly rounded; above highly polished, the under 

 surface and legs black, the antennae piceous-black, the funicle less 

 elongate than in the preceding; third joint notably shorter, not longer 

 than the next two, the club almost as long as the funicle; punctures 

 of the head very fine but rather close-set and distinct, those of the
