very promineut. Antennas scarcely reaching the hind margin of the pro- 

 thorax, feebly incrassate, joints four to ten as wide as or (the outer ones) a 

 little wider than long. Prothorax nearly as wide as the elytra across the 

 humeri; sides rather strongly rounded behind the middle, convergent and 

 feebly arcuate anteriorly, rounded posteriorly into the base, the basal 

 angles scarcely defined; margin serrulate and with close set, even fringe 

 of recurved hairs; disk moderately strongly, not closely, punctate, the 

 lateral rugose area not limited by a distinctly impressed line, but well 

 defined by the break in the vestiture. Elytra fully one-half longer than 

 wide, distinctly wider posteriorly, apex obtusely rounded; disk finely and 

 not closely punctate. Beneath with fine, sparser, appressed pubescence; 

 the anterior portion of the body more evidently punctate, the abdomen 

 very finely so. 



Length, 2.2-2.6 mm. 



Described from eight examples taken at Pomona, 

 Pasadena and Riverside. 



D. musculus agrees with D. lineellus in the coarse, 

 closely appressed vestiture without trace of erect hairs, 

 but differs in its smaller size, less robust form, and uni- 

 form disposition of the pubescence. 



64. Dasytes clementse, sp. nov. 



Moderately elongate and convex, polished, black with strong greenish 

 aeneous lustre, legs entirely rufotestaceous; palpi and antennae blackish, 

 the latter with the first three or four joints pale, the basal joint sometimes 

 more or less obscure. Pubescence entirely luteo-cinereous, rather long, 

 suberect, consisting, especially on the elytra, of somewhat uniformly 

 mixed, shorter, more inclined and recurved, and longer, a little less in- 

 clined, hairs. Head narrower than the prothorax, sparsely, moderately 

 finely punctate, and with the usual frontal impressions. Antennas (male) 

 distinctly longer than the head and prothorax, joints all longer than wide; 

 in the female scarcely longer than the head and thorax, the intermediate 

 joints barely longer than wide, the eleventh as long as the two preceding 

 in both sexes. Prothorax about one-half wider than long, widest and 

 rather strongly rounded behind the middle, quite strongly convergent in 

 front, a little less so behind; hind angles obtuse but distinct, front angles 

 rounded, side margins serrulate; disk finely, sparsely punctate, with an 

 abruptly limited rugose area. Elytra less than half wider than the pro- 

 thorax, slightly wider behind the middle; apex broadly rounded, finely 

 distantly serrulate; disk rather sparsely but moderately coarsely punctate. 

 Beneath finely, sparsely punctate and pubescent. 



Length, 2.5-3 mm.
