584 Goleopterological Notices, VI. 



testaceous toward base; pubescence luteo-cinereous, moderately loug and 

 coarse, not very dense and closely decumbent, not intermixed with erect hairs. 

 Head large, only slightly narrower than the prothorax, broadly convex, finely 

 and not very closely punctate, the impressions obsolete; epistoma short, with 

 a thin coriaceous extension, the labrum short, transverse, feebly arcuato- 

 truncate at apex; eyes small, basal, convex and prominent; antennae slender 

 and filiform, rather longer than the head and prothorax, the penultimate joints 

 fully as long as wide. Prothorax two-thirds wider than long, the sides sub- 

 parallel, broadly and rather strongly arcuate, somewhat more obviously so to- 

 ward base, the edges feebly serrulate; basal angles very broadly obtuse; apex 

 and base feebly arcuate and subequal; disk evenly and strongly convex from 

 side to side, finely but strongly and rather closely punctate, the marginal 

 fringe rather long, dense and conspicuous. Elytra one-half longer than wide, 

 one-fourth wider than the prothorax, the sides subparallel and nearly straight, 

 obliquely convergent behind, the tip narrow, subtransversely truncate and 

 strongl}^ serrulate, not at all dehiscent at apex, the sutural angles right and 

 not rounded; disk rather finely but strongly punctate, the punctures somewhat 

 close-set. Under surface thinly clothed with rather long and luteo-cinereous 

 pubescence. Length 1.9 mm.; width 0.75 mm. 



California (north of San Francisco). 



Of this interesting form I have before me three specimens from, 

 as many distinct localities ; of these only one satisfies the above 

 description, this example having the fifth ventral broadly trun- 

 cate and being without doubt the male. The other two speci- 

 mens have darker legs, the femora in one being blackish, and a 

 broadly and evenly rounded elytral apex ; the head in one of these 

 two specimens is smaller than in the other and both have the 

 fifth ventral more or less evenl}^ and broadly truncate at tip. It 

 is probable that there is some specific difference which cannot be 

 advantageously' defined at present. 



3. D. otiosus n. sp. — Elongate, rather strongly convex, subparallel, 

 strongly shining, the integuments very obsoletely and minutely rugulose; 

 legs ferruginous, the femora blackish ; antennae piceous-black, testaceous to- 

 ward base, the first joint blackish; pubescence long, subdecumbent, rather 

 coarse, somewhat sparse, pale fulvo-cinereous iu color, without erect hairs. 

 Head transverse, three-fourths as wide as the prothorax, finely and sparsely 

 punctate, the impressions obsolete; epistoma rather long and narrow, truncate, 

 the labrum short and subtruncate; eyes small and convex; antennae rather 

 short, nearly one-half longer than the prothorax, very feebly and gradually 

 incrassate, the penultimate joints slightly wider than long. Prothorax three- 

 fifths wider than long, the sides very feebly convergent, evenly and rather 

 feebly arcuate from base to apex, the edges scarcely serrulate; basal angles 

 very obtuse but not obliterated ; apex truncate, slightly narrower than the 

 base, the latter broadly arcuate; disk finely, sparsely punctate, more closely
