punctate. Legs rather slender, front coxse distant from the front margin of the 

 presternum by a little more than their own length, middle coxse separated by 

 fully one-fourth the coxal width ; metasternum very little longer than the first 

 ventral. 



Male. — Front and middle tibiae rather feebly, but obviously bent and nuicro- 

 nate internally at tip ; first joint of front tarsi dilated; last ventral not longer 

 than the preceding, the tip elevated and subacuminate. 



Female — Not seen. 



Length 2.5 mm. 



Hab.—New Mexico (Coolidge). One example sent by Mr. 

 Wick ham. 



This species is nearest pubescens, but is at once separable by the 

 shorter metasternum, very coarsely punctate prothorax, finer elytral 

 punctuation, pale color (perhaps not constant) and sexual characters. 

 The male tibia? are here fashioned as in all other members of the 

 genus except pubescens, but are less strongly sinuate and mucronate 

 internally at tip than usual. The structure of the tip of the fifth 

 ventral is nearly as in pubescens, and is not seen elsewhere. 



C fiilva Com. — Fulvous or yellow-brown, rather slender, moderately eon- 

 vex, pubescence fulvous, long, plentiful, the hairs of the intervals longer and 

 more erect. Head about as wide as the base of the prothorax, very finely 

 sparsely punctuUte; tempora moderate, parallel; eyes rather small, not much 

 moit' prominent than the tempora. Antenna? with the first joint of club as broad 

 as long, second a little transverse, all the other joints longer than wide, the 

 eighth but slightly so. Prothorax cordate, sides rather distantly serrulate, some- 

 times subangulate near the middle; punctuation distinct and moderately close 

 but not coarse, posteriorly foveate. Elytra rather finely seriately punctate, the 

 intervals nearly as strongly punctate. Beneath subobsoletely punctate ; meta- 

 sternum subequal in length between the coxse to the post-coxal part of the first 

 ventral, but distinctly shorter than the first ventral along the median line. Mid- 

 dle coxa? separated by nearly one-third the coxal width; last ventral in both 

 sexes not quite so long as the two preceding united. Legs slender. 



Mule. — Front and middle tibia? sinuate and mucronate internally at tip; last 

 ventral evenly rounded at tip, the apical margin slightly reflexed ; surface 

 scarcely at all impressed. (PI. IV, fig. 40). 



Female.— Tibise simple, last ventral nearly as in the male, the apical margin 

 less visibly reflexed. 



Length 1.7-2 mm. 



Hub. — A cosmopolitan species of which I have seen specimens 

 from Massachusetts, Virginia, Kentucky, Michigan and Lower Cali- 

 fornia (San Jose del Cabo). 



The small size, pale color, feebly punctate inferior surface and 

 wider ninth and tenth antenna] joints will readily separate from all 

 other similarly pubescent species. 



C. varicolor ap. nov. — Color varying from yellowish brown to piceous, 

 often uniform throughout, but more commonly piceous brown, with the elytra
