testaceous towaril hase; pubescence luteo-cinereous, moderately lonj^ aiut 

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

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

 and not very closely punctate, the imi)ressions obsolete; epistoma short, with 

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

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

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

 fully as long as wide. Prothorax two-thirds A\ider than long, the sides sub- 

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

 ward bcase, the edges feebly serrulate; basal angles very broadl}- obtuse; apex 

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

 side to side, finely but strongly and rather closely ])unctate, the marginal 

 fringe rather long, dense and conspicuous. Eh/Ira 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 

 strongly serrulate, not at all dehiscent at apex, the sutiiral 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 

 jnibescence. Length 1.9 mm.; width 0.75 mm.

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 evenly and broadly truncate at tip. It 

 is probable that there is some specific difference which cannot be 

 advantageously defined at present. 



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

 strongly shining, the integuments very obsoletelj^ and minutely rugulose^ 

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

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

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

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

 punctate, the impressions ol)solete; epistoma rather long and narrow, truncate, 

 the labrum short and subtruncate; ej'es small and convex; antenna; rather 

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

 incrassate, the penultimate joints slightly Avider 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, moi-e closely
