Elongate, shining, black, the antennce (the club excepted) and tarsi ferruginous. Head somewhat exserted, 



deeply foveate between the very prominent eyes, and without definite constriction behind them, the 

 exposed basal portion and the interocular space closely punctate; rostrum short, strongly, transversely, 

 subquadrangularly dilated at the apex, closely, coarsely punctate. Prothorax somewhat convex, a little 

 broader than long, rounded at the sides, feebly bisinuate at the base, constricted and much narrowed in 

 front ; closely, coarsely punctate, except along the smooth, mesially dilated, cariniform median line, 

 without definite basal depression. Scutellum very small, transverse. Elytra slightly wider than the 

 prothorax, long, parallel to beyond the middle, flattened on the disc ; punctato-sulcate, the interstices 

 narrow, raised, and faintly uniseriate-punctate. Ventral segments 1 and 2 narrowly sulcate down the 

 middle in the <$ . 



Length 5-64, breadth li-lf millim. 



Eab. Mexico, Omilteme in Guerrero 8000 feet (E. E. Smith). 



Three examples from Omilteme; a fourth (immature) from Las Vigas {Edge) 



probably belongs to the same species. More elongate and less rugose than the 



■ 



Guatemalan C. rugosus, the exposed basal portion of the head not so coarsely punctate, 



* 



the prothorax relatively wider and with a conspicuous smooth, raised, median line, 

 the elytra very little broader than the prothorax, with faintly punctate interstices. 

 The rather convex, subcarinate, closely punctured prothorax and the longer and strongly 



dilated rostrum separate C. puncticeps from C.

3. COSSOIIUS rUgOSUS, sp. n. (Tab. II. figg. 15, 15 a, 6 .) 



Moderately elongate, shining, black, the elytra with the humeri and a very faint subapical patch (extending 

 forwards towards the shoulders) indeterminately rufescent, the base of the antennae and the tarsi more 

 or less ferruginous. Head exserted, slightly depressed down the middle between the prominent, rounded 

 eyes, and without definite constriction behind them, the exposed basal portion and the interocular space 

 densely, coarsely punctate ; rostrum short, stout, strongly, transversely, subquadrangularly dilated at 

 the apex, coarsely, densely punctate ; antennae stout. Prothorax somewhat convex, a little broader 

 than long, rounded at the sides, feebly bisinuate at the base, constricted and narrowed in front ; coarsely, 

 densely punctate, sharply carinate posteriorly, without definite basal depression. Scutellum small,

transverse. Elytra much wider than the prothorax, moderately long, subparallel, flattened on the disc, 

 the humeri subangular ; coarsely punctato-sulcate, the punctures subtransverse and closely packed, the 

 interstices narrow, raised, and strongly uniseriate-punctate. Beneath closely punctate; ventral segments
