sides strongly arcuate ; disk ratlier finely bnt strongly, sparsely punctate, more 

 densely so and somewhat scabrous toward the sides. Elytra short, not quite as 

 long as wide, equal in width to the prothorax, broadly rounded behind, the 

 asperities moderate in size, feeble toward base, closer and stronger toward 

 apex. Length 5.5 mm. ; width 3.4 mm. 



California (San Francisco). 



In ciliatus the prothorax is less strongly narrowed from base 

 to apex, not more than twice as wide as its maximum length and 

 is scarcely more than twice as wide as the head, and the elytra 

 are much more densely asperate. The proportions of the typical 

 ciliatus are 6.5 by 3.8 ram. I have carefully collected large colo- 

 nies of ciliatus, and believe that there are several forms which 

 are at least racial or varietal, some localities jdelding specimens 

 of a very much larger average size than others, with differences 

 in color, relative size of the head, sculpture and other minor fea- 

 tures. 



EUSATTl'S Lee. 



The following species is allied to duhius Lee, differing in its 

 smaller size and dull integuments : — 



Ell. nanus u. sp. — Oblong-oval, strongly convex, dull, the pronotum 

 more shining and simply alutaceous, deep black, the antenna?, labrum, trophi 

 and tarsi dark rufous, subglabrous, each puncture bearing a very small de- 

 cumbent hair more noticeable near the sides of the pronotum, the hypomera 

 with long projecting hairs near the edges. Head one-half as wide as the pro- 

 thorax, strongly but not very densely punctate, the occiput impunctate; epi- 

 stoma moderately sinuate in the middle, the margin abruptly reflexed; antennae 

 slender. Prothorax twice as wide as long, the apex deeply emarginate and 

 three-fifths as wdde as the base, the latter deeply bisinuate, with the angles 

 posteriorly acute and prominent: apical angles advanced and narrowly rounded; 

 sides evenly and rather strongly rounded; basal margin with a fringe of very 

 short yellowish hairs; disk finely and sparsely punctate, narrowly reflexo-ex- 

 j)lanate at the sides, the punctures very minute and feeble toward the middle. 

 Elytra quite distinctly longer than wide, slightly more than twice as long as 

 the prothorax and barely as wide, subovate, the sides arcuate; apex broadly 

 rounded, the apical margin feebly subexplanate; disk slightly uneven, finely 

 simrsely and submuricately punctured. Epiplciirx narrow throughout, glab- 

 rous, sparsely wrinkled, deeply imi)ressed near the apex, the outer margin de- 

 scending. AhdoDien finely granulato-reticulate, convex, alutaceous, very finely 

 feebly and sparsely punctulate, each puncture l)earing a small decumbent hair; 

 legs sparsely and coarsely sculptured, the femora sparsely and coarsely pubes- 

 cent. Length 6.0-8.0 mm. ; width 3.4-4.8 mm.
