 eighth. Prothorax rather long and well developed, scarcely one-half wider 

 than long; apex ahont two-thirds as wide as the base, the latter transverse, 

 broadly, feebly bisinuate, the basal angles acute but not very prominent 

 posteriorly ; sides rather strongly arcuate anteriorly, becoming parallel and 

 nearly straight in basal three-fifths ; disk very finely, sparsely punctate, the 

 punctures becoming more distinct but still fine and rather sparse toward the 

 sides ; lateral margins coarsely beaded. Elytra but very slightly more than 

 twice as long as the prothorax, not very strongly declivous and rather acutely 

 rounded behind, very feebly subrugulose especially toward apex, the punc- 

 tures sparse but rather large, deeply impressed and very distinct, each bearing 

 a very fine elongate recumbent seta, the vestiture not at all conspicuous. 

 Abdomen sparsely but unusually coarsely and distinctly punctured. Femora 

 coarsely but sparsely punctate. Length 13.0 mm. ; width 5.4 mm. 



California (Lake Co.) Mr. Fuchs. 



This species in general form can be compared only with elongata, 

 but is distinguished from it not only by its longer elytral setae, but 

 by its distinctly different antennal structure, the third joint in elon- 

 gata being less than twice as long as the second, and the tenth joint 

 a little wider than long. In the type the two inner of the three 

 eroded grooves are just traceable. 



C. parallela n. sp. — Oblong-elongate, parallel, with the sides straight, 

 rather depressed, the elytra slightly shining, the pronotum very strongly 

 alutaceous. Head rather densely, somewhat finely punctate, the antenna? 

 moderate. Prothorax rather long and well developed, scarcely one-half wider 

 than long, the apex nearly three-fourths as wide as the base, the latter 

 broadly, rather strongly bisinuate, the median lobe broadly arcuate, the 

 basal angles acute and not rounded but not projecting posteriorly beyond the 

 median lobe ; sides moderately arcuate anteriorly, nearly parallel and straight 

 in basal two-thirds ; disk cotirsely, very conspicuously and moderately densely 

 punctured, more sparsely and finely but still very distinctly so toward the 

 middle ; marginal bead rather fine. Elytra about twice as long as the pro- 

 thorax, feebly rugulose, quite distinctly so toward apex, rather strongly, 

 unevenly and moderately densely punctate, the punctures rather coarse, each 

 bearing a long, subrecumbent, fulvous seta, the vestiture slightly conspicuous. 

 Abdomen sparsely, very finely and feebly punctate. Length 11.0 mm. ; width 

 5.0 mm.

There is a very feeble trace of the approximate elytral ridges 

 mentioned under imncticollis, but otherwise there is no resem- 

 blance between these species ; in fact parallela is quite an isolated 

 form, there being none other with which I can compare it, the 

 rather depressed parallel form, distinct pubescence and coarse pro-
