Southern Californiu. Mr. H. C Fall. 



The female described above has the fifth ventral rounded be- 

 hind, the apex subtruncate in the middle, the genital segment 

 being perfectly flat and even and strongly-, evenly rounded at the 

 apex. In general form and vestiture this species more nearly 

 resembles macer, of the next group, than any member of the 

 breviu senilis section of the genus, but difiers in its coarser and 

 sparser elytral punctures and bicolored legs. 



7. D. fastidiosilS n. sp. — Elongate and subparallel, rather depressed, 

 shining, l)lack with a feeble seneous lustre; legs blackish, the anterior and 

 Intermediate tibi* slightly rnfescent especially toward base; antenna) black; 

 piibescence rather long, suberect, cinereous, moderately dense, intermingled 

 ■with stiff sparse erect black setce anteriorly, which become pale, abundant and 

 scarcely distinguishable from the ordinary pubescence on the elytra. Head 

 about two-thirds as wide as the prothorax, transverse, polished, the punctures 

 strong, rather close and slightly unequal in size; frontal impressions very 

 feeble; epistonia rather long, the labrum broadly rounded; eyes prominent; 

 antennse subfiliform, not quite as long as the prothorax, the penultimate 

 joints slightly wider than long. Prothorax fully two-thirds wider than long, 

 the sides rounded, a little more convergent anteriorly, feebly serrulate; basal 

 angles obtuse but not rounded, minutely prominent and sliglitly reflexed; 

 disk polished, finely Ijut strongly, rather closely punctured, broadly rugose 

 near the sides. Elytra a little more than one-half longer than wide, one-third 

 wider than the prothorax, the sides feebly arcuate and just visibly dilated 

 behind; apex broadly and evenly rounded; disk finely but strongly and 

 rather densely punctured. Abdomen minutely and closely punctulate, sparsely 

 pubescent. Length 2.9 mm.; width 1.15 mm. 



California. 



This species is distinct in having the scattered erect setffi quite 

 well developed anteriorly but subobsolete on the elytra; it is de- 

 scribed from a female from an unrecorded part of the State, and 

 is apparently' unique. 



8. D. macer n. sp.— Parallel, rather narrow, moderately convex, pol- 

 ished, black, the legs and antennas black throughout; pubescence cinereous, 

 moderate]}' dense and somewhat short, not very coarse, suberect and inter- 

 mixed toward the sides with a few erect black sette on the pronotum, subde- 

 cumbent, even and without erect hairs on the elytra. Head but slightly Avider 

 than long, only a little narrower than the prothorax, polished and smooth 

 throughout, minutely and sparsely punctate, the impressions very feeble; 

 epistoma and labrum moderately elongate, the latter arcuato-truncjite at apex; 

 eyes rather small and iirominent; antenmc long and thick but filiform and 

 loose, nearly two-fifths as long as the bodj' and much longer than the head and 

 prothorax, the joints rounded. Prothorax nearly three-fifths wider than long,
