<$ . Eostrum stout, moderately curved ; femora closely set along their lower edge with short, fulvous, hair- 

 like scales ; ventral segments 1 and 2 broadly and deeply excavate down the middle, and each with two 

 very small, transversely placed, rugulose fovese in the excavation (the foveae on 1 widely separated, those 

 on 2 subcontiguous and placed near its anterior margin), 5 with a very large, transverse fovea in 



the middle (fig. 27 a). 

 2 . Eostrum with the anterior portion polished, a little longer, arcuate, and more slender, appearing more 



abruptly thickened at the base.

A common insect in Central America and apparently replaced southward by C. fallax. 

 The elytra usually have the sides broadly and indeterminately rufescent, but the entire

 suture. The peculiar ventral and femoral characters of the male have hitherto

Very elongate, narrow, subfusiform, alutaceous, moderately shining, piceous, the elytra with the sides broadly 

 rufo-fulvous and the sutural region black, the antennae (the club excepted), tip of the rostrum, and tarsi 

 ferruginous. Head closely, finely punctate, deeply transversely sulcate between the eyes : rostrum com- 

 paratively slender, cylindrical, widened towards the base and apex, somewhat closely punctate; antennae 

 with a rather slender funiculus and a moderately stout club. Prothorax oblong-oval, much longer than

broad, strongly constricted in front ; closely, somewhat coarsely punctate, with an abbreviated impunctate 

 median line. Scutellum strongly transverse, smooth. Elytra scarcely wider than the prothorax, gradually 

 narrowing from the base, the apices bluntly and separately rounded ; somewhat coarsely seriate-punctate, 

 the punctures placed in faint striae, the two inner striae divergent at the apex, the interstices flat, minutely 

 uniseriate-punctate, the second and third raised and convex on the apical declivity, the third and ninth 







confluent just before the tip. Legs short ; femora unarmed ; tarsi rather narrow.
