Dr. LeConte in his table which can i-eceive this species, on account 

 of the structure of the fourth joint of the niaxilhiry palpi; it can, 

 however, for the present be placed after higuhre. 



C proxiltmm n. sp. — Form moderately slender, depressed. Color 

 throughout lathor dark brownisli-red ; head very slightly darker, castane- 

 ous ; femora paler, yellowish-testaceous ; pubescence of head and pronotum 

 very coarse, setiform, sparse, erect, that of elytra and abdomen slightly more 

 dense, finer, erect, fulvous. Head much longer than wide ; sides behind 

 the eyes parallel and very slightly arcuate, broadly rounded behind ; base 

 broadly and very feebly emarginate ; eyes small, truncate behind, slightly 

 prominent ; width across the eyes scarcely as great as at their own length 

 behind them ; epistomal region adjoining them anteriorly about two-thirds 

 as wide as the head, sides parallel and straight, broadly truncate and very 

 feebly sinuate anteriorly, angles rounded ; antennal tuberculations strongly 

 marked, intermediate surface feebly declivous, slightly more strongly im- 

 pressed near them and slightly more sparsely punctate than the occiput ; the 

 latter broadly convex, polished, coarsely deeply evenly sparsely and sub- 

 variolately punctate, punctures round, separated in the middle by about two 

 and one-half times their own widths, at the sides smaller and slightly closer; 

 large punctures at one and one-half times the length of the eye l)ehind the 

 latter, the upper one the larger and elongated ; under surface finely and 

 sparsely punctate, polished, finely rugulose ; maxillary palpi long, second 

 joint very feebly arcuate, distinctly shorter than the third which is conical, 

 rather abruptly narrowed near the base, about two and one-half times as 

 long as wide, fourth flattened, olilique, conical, very slightly longer than 

 wide at base, two-thirds as wide as the third and one-fourth as long, color 

 pale ; mandibles nearly black ; antennae much longer than the head, 

 slender, pubescence toward tip rather coarse, very close and dense, bright 

 fulvous, basal joint as long as the next three together, second nearly three- 

 fourths as long as the third, equal to the fourth, joints four to eight increas- 

 ing very slightly in length, the latter conical, twice as long as wide, ninth 

 longer than th<» tenth, equal to the last, the latter very slightly longer than 

 wide. Prothorax much shorter and \n\i slightly narrower than the head ; 

 sides about parallel, rather strongly arcuate ; apex slightly longer than the 

 base, broadly and very feebly arcuate, angles obtuse, narrowly rounded, base 

 transverse in the middle, angU's rather broadly rounded ; disk extremely 

 highly polished, scarcely one-sixth longer than wide, l)roadly convex, coarsely 

 and rather densely punctate, i)unctures roundly impressed, without trace of 

 serial arrangement; broad mt>dian area, and on each side a narrower oblique 

 line beginning near the apical angles and continuing to the base, iiii]>uuc- 

 tate ; two setigerous punctures of scutelluni very widely separated. Elytra 

 at base as wide as the head ; sides parallel and very feebly arcuate ; together 

 broadly and rather strongly sinuate behind; apical angles rounded; disk 

 nearly one-third longer than the pronotum, depressed, flat, rather coarsely 

 evenly and very closely punctate, very highly polished. Abdomen about 

 as wide as the elytra; sides parallel and straight; border very strong on 

 the llrst four segments, slightly stronger toward base ; surface polished.
