impressed along the middle. Elytra slightly wider than the prothorax and 

 distinctly more than twice as long, the humeri not prominent laterally ; sides 

 subparallel, generally feebly arcuate, the apex somewhat obtusely rounded; 

 disk with moderate striae, becoming coarse near the base, the intervals flat, 

 slightly unequal, two to three times as wide as the strife, rather finely, not 

 densely, somewhat rugulosely and confusedly punctured throughout. Abdomen 

 finely, sparsely punctate. Prosternum broadly and very feebly impressed, 

 with two deep subapical fovese as in Onychobaris, but less distant ; coxae 

 large, separated by scarcely more than one-half of their own width. Length 

 3.5-4.3 mm. ; width 1.45-1.8 mm. 



Arizona. 



The four specimens in my cabinet form a perfectly homogeneous 

 series, and represent a species differing greatly from cribrata in the 

 white pubescence, uniformly distributed and without trace of con- 

 densation behind the middle or at the base of the third interval, also 

 in its larger size, denser pronotal punctures and completely black 

 body and legs. 



3 Stictobaris subacuta n. sp. — Elongate-elliptical, convex, shining, 

 piceous-black, the legs rufous ; seta? long, very robust, uniformly distributed 

 and without trace of condensation at the base of the third interval or behind 

 the middle. Head very finely, sparsely and feebly punctate, minutely reticu- 

 late and alutaceous, the groove rather shallow but distinct ; beak somewhat 

 coarsely but sparsely punctate, moderately strongly arcuate and subequal in 

 length to the prothorax ; antennae moderate, the club somewhat robust, nor- 

 mal, the second funicular joint short and but slightly longer than the third. 

 Prothorax scarcely one-third wider than long, feebly convergent and nearly 

 straight at the sides to apical fourth, then abruptly, strongly narrowed and 

 tubulate, the apex truncate and fully two-thirds as wide as the base, the latter 

 transverse, the median lobe small and rather feeble, rounded ; disk with a 

 very narrow, incomplete and subobsolete impunctate line, the punctures 

 nearly as in cribrata, but rather closer. Elytra one-fourth wider than the 

 prothorax and nearly two and one-half times as long, the humeri feebly 

 tumid, not prominent laterally ; sides parallel and feebly arcuate ; apex 

 gradually, rather narrowly parabolic ; disk with somewhat narrow, moder- 

 ately deep strise, becoming coarser and somewhat crenulate near the base, the 

 intervals flat, from one-half wider than, to nearly twice as wide as, the grooves, 

 the punctures arranged in nearly even single series, fine and remote but be- 

 coming very coarse and rather close-set toward base, more or less confused on 

 the third. Length 3.2 mm. ; width 1.25 mm. 



New Mexico (Las Yegas). 



Closely allied to cribrata, but well distinguished by its much 

 narrower and more convex form, less truncate elytra, more elongate 

 prothorax, and especially by the much longer, still more robust and
