yellowish in color. Sead only slightly wider than long, paraholic behind the 

 eyes, the latter moderate in size and rather convex and prominent ; occiput 

 scarcely vertical and obtuse in profile. Antennae long and slender, gradually 

 incrassate toward tip, more thap )^ as long as the body, the basal joint cylin- 

 dric, twice as long as wide and nearly as long as the next two ; second slightly 

 thicker than the third and % longer than wide ; three to six equal in thick- 

 ness, slender, cylindric ; seventh a little thicker ; third %, fourth ^, fifth %, 

 sixth %, seventh %, longer than wide ; eighth slightly thicker, feebly obconic, 

 % longer than wide and distinctly longer than the seventh or ninth, the latter 

 subequal to the tenth, but little longer than wide ; eleventh elongate, grad- 

 ually pointed, nearly as long as the two preceding but not thicker. Prothorax as 

 long as wide, conic, the sides feebly arcuate ; apex subtubulate, truncate and 

 }4 as wide as the base, the latter broadly arcuate ; disk even and not in the 

 least impressed ; base scarcely 3^ wider than the head. Elytra nearly % longer 

 than wide, twice as long as the prothorax and about % wider, ovoidal, widest 

 near basal third, gradually narrowed behind, the apex narrow but somewhat 

 obtuse ; disk feebly impressed near the suture toward base ; humeral plica 

 distinct and elongate ; subhumeral impression large and pronounced ; suture 

 not at all beaded. Abdomen pubescent. Legs moderately long, the femora 

 strongly clavate, the posterior less strongly so, with the club occupying apical 

 half. Length 1.65-1.8 mm. ; width 0.65-0.75 mm. 



Texas (Colorado River). 



The description refers to three male examples, two other speci- 

 mens taken at the same time, which are undoubtedly the female, 

 being decidedly smaller in size, still paler and more ferruginous 

 in color and with the antennae scarcely ^ as long as the body, and 

 more strongly and less gradually incrassate through the last four 

 joints ; the femora are equally strongly clavate. 



This species is rather closely allied to longicorne, but may be 

 distinguished by the paler coloration, rather less elongate antennae, 

 and shorter, stouter and more rhombic form. 



12. C. den tiger n. sp. — Rather stout, polished and subimpunctate; 

 piceous-black, the entire elytra rather pale ruf o-testaceous ; legs and antennae 

 rufous throughout; pubescence moderate in length and abundance, rather pale 

 on the elytra. Head relatively large, slightly wider than long, semicircular ly 

 rounded behind the eyes, which are moderately developed and not noticeably 

 prominent; pubescence coarse, abundant and flavate ; clypeal tooth long and very 

 conspicuous, parallel, convex, obtuse at apex. Antennas rather short and stout, 

 % as long as the body, the club decidedly abrupt but with its joints increas- 

 ing in width; second subcylindric, almost as thick as the first and much 

 thicker than the third, % longer than wide, as long as the next two; three to 

 seven almost exactly equal and about as long as wide, the fifth rather more; 

 eighth }4 wider than the seventh and }4 longer, oval, not quite as long as 

 wide; ninth similar to the ei hth but a little larger, the tenth tiistinetly wider
