tremely fine short pubescence. Head with vertex finely, sparsely punc- 
tured and pubescent, a well-defined triangular impression between the eyes, 
the eyes convex and of moderate size, muzzle short, no beak, antenne 
over one half length of body, second joint about one half as long as the 
third which is shorter than the fourth, outer joints moderately compressed, ~ 
about twice as long as wide, distal side slightly oblique. Pronotum quad- 
rate, three fourths as long as wide, front angles rounded, posterior angles 
acute though rounded at extreme apex and divergent, sides thickened and 
reflexed, not impressed at middle, with a strong ridge running from the 
middle of the sides obliquely and slightly forwards on to the disc which 
is only feebly channeled near the base, apical margin thick and strongly 
reflexed, the basal thinner and less reflexed. The scutellum black and 
truncate behind. The elytra elongate, with sides parallel and narrowly 
margined, but little wider than the prothorax, closely but indistinctly striate 
and with punctures not evidently defined, the alternate intervals percepti- 
bly more prominent, especially posteriorly, but not costiform, not reticu- 
lated. Middle and hind tibia slightly curved. Length 9 mm., breadth 3 mm. 
6 smaller, antennz reaching to beyond middle of body, seventh ventral 
segment broadly and deeply semicircularly emarginate. . 
? larger, 12 mm. in length by 4 mm. in breadth, antenne not reaching 
middle of body, posterior angles of pronotum right and less prominent, 
seventh ventral segment with small apical incisure closed at apex by mem- 
brane and with triangular impression extending forwards. 
Type male and female in my own collection, collected September 10, 
1916, at Gilroy Hot Springs, by Mr. L. S. Slevin. These, together with a 
third specimen, were kindly presented by the captor, after whom I take 
pleasure in naming it. 
This species, according to its physical characters, would) follow 
C. fervens Lec., as indicated by the latest table,* but according to 
its coloration would come closest to C. dimidiatus Lec. From the 
latter, which is confined to the Sierras.and northern California, 
it differs by having the pronotum and base of elytra of a scarlet 
rather than an orange color, by having the apical blue-black color 
not extending forwards as far as the middle of the elytra and by 
meeting the crimson squarely, whereas in the other it extends 
fully to the middle and to a greater extent at the suture than at 
the margins, by not having the side margin of pronotum impressed 
at the middle, and by having the posterior tibia slightly curved.
