Arizona (Peach Springs). 



The wings are moderately developed, rather distinctly hyaline 

 and iridescent, slender, a little more than three times as long as 

 wide, distinctly veined, about one-half longer than the prothorax 

 and nearly three-fourths as long as the elytra. 



This species is not closely allied to any other here described and 

 may be easily recognized by its parallel depressed form, very fine 

 elytral and coarse abdominal punctuation, and structure of the hind 

 wings. From rvfij^es, which it most nearly resembles in size of 

 the wings, it may be at once separated by its more depressed form, 

 shorter prothorax, feebler, finer elytral striaB and darker legs. 



ItJ It. cribricollis n. sp. — Oblong, rather strongly convex, moderately 

 shining, black ; legs rufous ; pubescence rather long, fine, somewhat sparse, 

 dark piceo-fulvous and not conspicuous. Head strongly transverse, feebly 

 convex, very deeply, rather coarsely and densely punctate ; upper lobe of eye 

 moderate ; antenufe ratlier robust, gradually but very moderately incrassate 

 through the four outer joints, third rather less than twice as long as the 

 second and very much shorter than the next two together. Prothorax moder- 

 ately transverse, scarcely two-thirds wider than long, feebly narrowed from 

 base to apex, the sides evenly and strongly arcuate throughout ; base trans- 

 verse, the sinuations rather feeble ; basal angles distinctly obtuse and very 

 narrowly rounded ; apex very feebly emarginate in circular arc, the apical 

 angles narrowly although quite distinctly rounded ; disk evenly convex, 

 coarsely, very deeply and extremely densely punctate throughout, the punc- 

 tures but slightly coalescent toward the sides. Scutelluni moderate, rather 

 transverse. Elytra scarcely three times as long as the prothorax and, behind 

 the middle, very slightly wider, broadly, parabolically rounded behind ; sides 

 feebly arcuate ; disk finely striate, the strife rather broadly but moderately 

 impressed, much more strongly so toward the sides and apex, somewhat finely 

 but deeply and very distinctly punctured, the punctures generally separated 

 by a little less than twice their own diameters ; intervals very feebly convex, 

 much more strongly so laterally, very finely and rather sparsely punctate. 

 Ahdoiuen polished, rather coarsely and moderately sparsely punctate, the 

 pubescence ratlier short and sparse but pale tiavo-cinereous and distinct. 

 Legs robust. 



Male. — Anterior tarsi moderately dilated, the second and third joints sub- 

 equal, the latter with the apical emargination rather broad and feeble ; inter- 

 mediate very feebly dilated; both pairs rather coarsely but densely squamu- . 

 lose beneath ; abdomen broadly and very feebly impressed in the middle 

 toward base. 



Length 5.8 mm. ; width 2.5 mm.

This species is quite distinct from any other known to me in its 

 coarse deep and very dense, but at the same time not greatly coales-
