12 MEMOIRS ON THE COLEOPTERA 



at the middle of the front, the impressions feeble; prothorax unus- 

 ually short, fully a third wider than long, widest near apical fourth, 

 the sides only very moderately oblique and rather feebly arcuate 

 thence posteriorly to the base (c?), or nearly to the base, where 

 they become strongly oblique (9), the acute margin attaining the 

 base, which is transverse, broadly, feebly bisinuate; surface distinctly 

 and evenly vermicularly rugulose throughout; elytra (cf ) evenly and 

 obtusely oval, widest at the middle, or ( 9 ) more acutely and ob- 

 liquely tapering apically and sometimes widest a little before the 

 middle, the punctures rather strong and deep, well separated, 

 coarser and dense laterally. Length (cf 9 ) 15.5-17.5 mm.; width 

 6.1-6.5 mm - California (Big Trees, Calaveras Co.) . sequoiarum Cr. 

 A Similar but a little larger and rather more elongate, the prothorax 

 similar throughout, except that it is less abbreviated, being about 

 a fourth wider than long; elytra (cf) not evenly and obtusely oval 

 but widest well before the middle, thence arcuately tapering to 

 the acute apex, the punctures similarly strong and deep and 

 everywhere closer; labrum similarly with a pronounced narrowly 

 truncate median lobe. Length (cT) 17.5 mm.; width 6.3 mm. 



California, Levette lugubris Csy. 



B Similar to lugubris throughout but with still somewhat less trans- 

 verse prothorax, in which the acute side margin does not attain 

 the base as in the two preceding, but abruptly terminates at a 

 considerable distance from the base; elytra (cf ) evenly and very 

 obtusely oval, widest at the middle, the punctures not so coarse, 

 more nearly as in sequoiarum but more close-set, subcontiguous, 

 the fovese very few, small, widely dispersed and inconspicuous. 

 Length (cf) 17.0 mm.; width 6.4 mm. California, Levette. 



sierricola Csy. 



C Similar to sequoiarum but more parallel, less ventricose and less 

 convex; head relatively a little larger; prothorax nearly a third 

 wider than long, as in sequoiarum throughout but with the sides 

 evenly converging and subevenly and distinctly arcuate from apex 

 to base, very little more converging near the base, the acute 

 margins attaining the base; elytra more oblong-oval and more 

 elongate, slightly more than one-half longer than wide, more 

 gradually pointed at apex though similarly widest at the middle, 

 the punctures much finer and feebler than in any of the three 

 preceding, substellate and sparse, but little larger or closer laterally ; 

 hind tarsi much longer, being nearly one-half longer than the 

 tibiae. Length (cf) 16.0 mm.; width 6.0 mm. (Big Trees, 



Calaveras Co.) longitarsis n. subsp. 



Body much smaller, less stout and not so convex 3 



3 Male and female differing greatly, the former more slender, the latter 

 very stout, with much larger and more transverse prothorax and 

 decidedly shorter antennae. Surface rather shining; head much 

 narrower than the prothorax, the labrum rather strongly lobed; 

 prothorax (c?) barely a fifth wider than long, the sides converging, 

 distinctly and subevenly arcuate from apex to base, the acute 

 margins strongly reflexed and attaining the base; surface rather
