168 AMERICAN COLEOPTERA. 



cnrinatum in the Smith collection, now owned by tiie National 

 Museum. 



93. A. atleniiatuni Smith. — Moderately elonpite, black ; pubescence rather 

 thiu, not appreciably more conspicuous beneath, somewhat condensed at the base 

 of the third elytral interval. Beak equal to or a little shorter than the head and 

 prothorax, rather stout, parallel, scarcely at all dilated, coarsely more or less 

 riigosely punctate, especially at the sides. First joint of antennae scarcely as 

 long as the next two. outer joints transverse, second joint usually not reaching 

 the eye. Front very little wider than the tip of the beak, punctate, not sulcate ; 

 eyes moderate. Prothorax rather more than two-thirds the width of the elytra 

 at humeri, as long as wide; sides subparallel and straight or feebly arcuate in 

 basal half, thence moderately narrowed and constricted. Punctures of surface 

 usually shallow, of moderate size and not very close, but sometimes distinctly 

 deeper, coarser and closer; basal fovea small, linear. Elytra more than one-half 

 longer than wide; humeri moderately prominent; sides feebly, arcuately 

 divergent to behind the middle; intervals about one-half wider than the strise, 

 slightly convex. First two ventral segments moderately punctate, the others 

 almost unpunctate ; legs moderate. Length 1.7-2 mm. ; .07-. 08 inch. 



Hab. — Michigan (Detroit), Ontario (Toronto), Illinois, Nebraska 

 (Knaus), Texas (Brownville, Wickham), Oregon (Wickham), 

 Southern California. 



A species of wide distribution and exhibiting a moderate amount 

 of variation in sculpture and proportion of parts. The Southern 

 California examples especially vary from the above description in 

 the longer, less coarsely punctate beak and more elongate basal 

 joint of tlie antennae. I do not, however, feel warranted in separa- 

 ting them. 



94. A. soliltiini n. sp. — Elongate, parallel, black ; legs red ; pubescence con- 

 spicuous, condensed at the bases of the third elytral intervals. Beak rather 

 stout, parallel, scarcely dilated, about as long as the head and prothorax ( % ), 

 somewhat longer (J); surface finely sculptured nearly to the tij), superficially, 

 more or less irregularly punctate throughout. Antennse moderate, first joint 

 about as long as the next two, second or third reaching the eye. Front substriate ; 

 eyes not prominent. Pi-othorax as long as wide, subcylindrical, moderately nar- 

 rowed and constricted in front, the front margin somewhat thickened ; surface 

 moderately punctate. Elytra nearly twice as long as wide, about one-half wider 

 than the prothorax; sides parallel; interval nearly flat, less than twice as wide 

 as the strife. Beneath not closely punctate; legs rather short, not slender. 

 Length 2 mm.; .08 inch. 



Hftb. — Western Texas, New Mexico. 



Described from three specimens in my own collection, kindlv 

 communicated by Captain Casey, and one each in the collections of 

 Dr. Hamilton and Mr. Fuchs. In all the specimens the metaster- 

 num bears at the middle of the posterior margin a laterally com-
