70 COLEOPTERA RHYNCHOPHORA. 



moderately coarse and close ; prosternum broadly longitudinally im- 

 pressed or concave at middle, separating the coxae by about two-thirds 

 their own width. Length, 3.6 mm. ; width, 1.65 mm. 



The type is a d^ from Cloudcroft, New Mexico, collected 

 by Mr. Knaus. With it I have placed a series from the 

 Chiricahua Mountains of Arizona (Clemence) and others 

 from Nogales, Arizona (Nunenmacher). One c^ from the 

 Chiricahuas agrees almost perfectly with the type; the other 

 examples are slightly stouter with the sides of the thorax a 

 little less convergent though obviously so, and there is a 

 more obvious confusion of the interstitial punctures of the 

 second and third elytral intervals. This species is plainly 

 close to aprica Csy, which is said, however, to be polished, 

 prothorax one-third wider than long, with sides almost 

 parallel and straight in basal two-thirds, and the elytral inter- 

 spaces but slightly wider than the striae. 



jB. tectiisn. sp. — Oblong oval, convex, black throughout, polished ; 

 setae long, white, subrecumbent and very conspicuous. Head finely 

 sparsely punctate, transverse impression broadly angulate in profile. 

 Beak stout, arcuate, not quite three-fourths as long as the prothorax, 

 quite densely punctate. First funicular joint nearly twice as long as 

 wide, second nearly as long as wide, following joints increasingly trans- 

 verse ; club oval, fully as long as the five preceding joints, polished and 

 glabrous in about basal half. Prothorax not quite one-fifth wider 

 than long, sides feebly arcuate, nearly parallel in basal half or two- 

 thirds, apex scarcely two-fifths the basal width ; disk coarsely densely 

 punctate, punctures separated by one-third to one-half their own 

 diameters, median smooth line narrow and incomplete. Scutellum 

 small, subquadrate. Elytra a little wider and three-fifths longer than 

 the prothorax, one-fifth longer than wide, sides parallel, striae moder- 

 ate, intervals about two-thirds wider than the striae, second and third 

 widest, interstitial punctures rather coarse, close set, and more or less 

 irregular or confused on nearly all the intervals, except toward the 

 apex. Beneath moderately coarsely closely punctate ; prosternum 

 feebly concave at middle, separating the coxae by slightly more than 

 half their own diameters. Length, 3.4 mm. ; width, 1.65 mm. 



Type. — From Chiricahua Mountains, Arizona. 



Described from a single example, apparently a male, col- 

 lected and given me by Mr. V. L. Clemence. 



By Casey's table this species would come between vesper- 

 tina and oblongula. Vespertina differs in its piceous-brown 

 color, the setae are said to be semi-erect and arranged with-
