but does not seem to fit any of the descriptions that are given by 

 Champion in the Biologia CentraH Americana, though it ap- 

 proaches C. depressicolis Boh. but does not quite agree with the 

 figure given* not having the distinct depression and short carina 

 at base of thorax and not such prominent eyes. 



C. ellipticollis n. sp. Shining, piceous with somewhat rufous 

 legs. Head with vertex very finely and sparsely punctured, more 

 coarsely punctured between eyes and moderately coarsely and 

 closely punctured towards apex of rostrum. Eyes moderately 

 prominent, sides of head convergent forwards and bowing around 

 eyes to base of rostrum, a deep and somewhat lengthened punc- 

 ture between the eyes, diameter of head across eyes about one 

 fourth greater than greatest breadth of rostrum. Rostrum about 

 one half length of thorax, basal portion about equal in length to 

 apical, as broad as long, with sides practically straight and paral- 

 lel, apical portion abruptly and quadrilaterally dilated, broader 

 than long and almost one third broader than basal portion. Joints 

 of funicle of antennae very gradually increasing in width out- 

 wards, the outermost joint slightly greater than one half width 

 of club. 



Prothorax fully one fourth longer than broad, base bisinuate, 

 sides constricted for short area at base, thence rather regularly 

 though narrowly arcuate until near apex where slightly con- 

 stricted. Surface convex and very slightly flattened above, mod- 

 erately coarsely, sparsely and somewhat regularly punctured at 

 sides, more finely and irregularly above, and somewhat coarser 

 near middle and basally, base slightly more depressed near median 

 line, giving the point of the median line the appearance of a vague 

 crista. 



Elytra not wider than thorax, surface slightly convex above, 

 deeply striate, coarsely and crenately punctured especially so in 

 basal half, intervals convex, with series of very vague punctures. 



Body beneath moderately coarsely and sparsely punctured at 

 middle, apical segment more closely and prothorax more coarsely 

 as well as closely punctured. 



Length 5 mm., breadth i. mm.
