completely unconstricted neai* the apex ; this character appears 

 however to be quite variable in some species, and especially /"ror*- 

 talis, in two specimens of which, taken by Mr. Wickham at Gree- 

 ley, Colorado, one has the prothorax entirely unconstricted and the 

 other — a larger female — very distinctly so. 



There are several points in the original description of vittatus 

 Kirby, which render it quite certain that the vitlatiis of LeConte is 

 not in reality that species, but an entirely different one. The de- 

 scription alluded to states that the body is narrow, clothed with 

 decumbent hoary pile, that the prothorax is punctured with rather 

 large scattered punctures, and that the elytra have three stripes. 

 None of these characters will apply to the vittatus of LeConte, 

 which is rather oval of body, sparsely clothed with very short 

 robust hairs, and having the punctures of the pronotum subcon- 

 fluent; they all apply strictly however to a series of specimens be- 

 fore me, taken at Puget Sound and in various parts of California, 

 and also to the published characters of poricollis Mann. They 

 also suit the description of virgatus in all but a few minor particu- 

 lars, such as the apparently longer prothorax with straighter sides 

 of that species. 



Some of the names suggested by LeConte will probably have to 

 be changed, because of previous employment, when the genus 

 Cleonus is monographically revised, unless the assignment of the 

 various species to different subgenera be considered sufficiently 

 distinctive. The new forms indicated in the table may be de- 

 scribed as follows : — 



C. graiidirostris. — Siiboval, moderately robust, convex, densely clothed 

 throughout with very short, recumbent squamiform and cinereous pubescence, 

 the punctures not at all concealed. Head rather finely, the beak more coarsely, 

 punctate, the punctures rather sparse ; beak subequal in length to the pro- 

 thorax, distinctly carinate, the carina terminating abruptly bt^hind in a large 

 fovea between the eyes. Prothorax rather short, one-third wider than long, 

 the apex broadly arcuate, much narrower than the base, the latter rather 

 acutely cusped in the middle, but slightly oblique thence to the basal angles ; 

 sides almost parallel toward base, convergent and slightly sinuate anteriorly; 

 disk with a deep, slightly elongate excavation toward base, not carinate ante- 

 riorly, very coarsely, sparsely punctate with the pubescence partially denuded 

 in a broad dark oblique submarginal vitta. Elytra twice as long as wide, about 

 one-fourth wider than the prothorax ; sides parallel and nearly straight, 

 oblique and nearly straight in apical third or fourth, the apex rather nar- 

 rowly subtruncate ; humeri obliquely rounded to the base of the prothorax ; 

 disk with unimpressed series of coarse, very deep, rather distant punctures.
