nent causing side of head as a result to become suddenly con- 

 stricted to base of rostrum. Vertex with a moderately deeply 

 impressed almost circular puncture slightly above the eyes, di- 

 ameter of head across eyes not quite twice as broad as greatest 

 breadth of rostrum. Rostrum about half the length of the thorax, 

 basal portion about equal to apical, broader than long, with 

 straight and parallel sides, apical portion but slightly dilated, 

 quadrilateral and broader than long. Joints of funicle of antenna 

 gradually increasing in width outwards, the outermost greater in 

 breadth than one half diameter of club. 



Prothorax slightly longer than broad, base bisinuate, sides 

 from narrow basal constriction gradually rounded and widened 

 to one fourth distance from base, then straight and but slightly 

 convergent to one fourth distance from apex where broadly 

 rounded to distinctly constricted apex. Surface convex on sides 

 and dorsally in front but flattened in a basal and median triangular 

 area, coarsely, regularly and moderately closely punctured at sides, 

 somewhat more finely and distinctly at outer portion above and 

 still more coarsely and closely at median basal portion. Basal 

 portion just perceptibly depressed and without carina. 



Elytra distinctly wider than thorax, surface slightly convex, 

 deeply striate^, coarsely punctured, punctures coarser and deeper 

 at base, intervals almost flat, very minutely uniseriately punctured. 



Body beneath sparsely punctured, more closely in front. 



Length 6 mm., breadth 1.5 mm. 



Type in my collection, paratypes in U. S. Nat. Mus. and Cal. 

 Acad, of Science. 



This species is described from a small series of specimens re- 

 ceived from Texas through Mr. Beyer, some years ago. It was 

 given me as C. piniphilus^ probably because C. ponderoscc, which 

 it closely resembles, then passed in most collections as that species. 

 It is however, very distinct from C. piniphilus and distinguishable 

 from C. ponderosce, its closest relative in our fauna, by its more 

 prominent eyes and shorter rostrum. Its thorax is also more 

 bulbous, suggesting C. concinnus, but the eyes of this species are 

 even more prominent and the apex of the rostrum much more 

 dilated, besides having other distinguishable characters. It may 

 possibly be the same as one of the species described from Mexico
