what less incrassate dlstally, the third joint slightly longer than the 

 first; prothorax notably narrower and more elongate, very much nar- 

 rower than the head, the sides broadly rounded anteriorly, similarly 

 moderately converging and straight to the base, the punctulation still 

 finer and sparser than in occidua and not evidently asperulate; elytra 

 narrower though about four-fifths wider than the prothorax and mach 

 longer; abdomen similar but much more sparsely punctulate. Length 

 2.25 mm.; width 0.53 mm. California (Monterey Co.) — laclda n. sp. 



Form more elongate and narrower than in occidua, i\xQ prothorax more elon- 

 gate, rufo-piceous in color, the abdomen darker; legs pale, the antennae 

 fuscous except at tip and toward base; vestiture short but close and 

 rather distinct; head as in occidua, minutely and sparsely punctulate 

 but having the punctures strongly asperate on the occiput; antennae 

 nearly similar, the three penultimate joints decidedly transverse ; pro- 

 thorax very evidently elongate, not quite as wide as the head, the base 

 four-fifths as wide as the disk, the sides rounded anteriorly; punctula- 

 tion minute, rather sparse, very slightly asperulate ; elytra but slightly 

 transverse, four-fifths wider and two-fifths longer than the prothorax, 

 the punctulation rather sparse and asperulate; abdomen distinctly nar- 

 rower than the elytra, parallel with broadly arcuate sides, the sculpture 

 close-set and distinctly asperulate, finely so posteriorly, coarsely 

 and more sparsely toward base, the impressions differing from those of 

 the allied species in having numerous somewhat coarser but feeble 

 punctures, irregularly scattered and not in close contact. Length 2.5 

 mm. ; width 0.55 mm. California (Los Angeles Co. — Pomona Mts.), — 

 H. C Fall aspernla n. sp. 



Form still more slender and darker in color, blackish-piceous, the legs tes- 

 taceous, the femora in large part piceous; antennae fuscous, paler at 

 tip and toward base; pubescence inconspicuous; head wider than long, 

 parallel at the sides behind the eyes, thence broadly rounded through 

 the base, unimpressed, obsoletely and remotely punctulate; antennae 

 nearly attaining the middle of the elytra, normally incrassate distally, 

 the second and third joints long, equal, the first somewhat shorter and 

 stouter; prothorax only very slightly longer than wide, somewhat nar- 

 rower than the head, nearly as in occidua but rather more depressed and 

 more finely, sparsely and obsoletely punctulate; elytra about three-fifths 

 wider and two -fifths longer than the prothorax, only slightly wider 

 than long, sparsely and very minutely punctulate; abdomen parallel with 

 arcuate sides, as wide as the elytra, the sculpture scarcely at all asper- 

 ulate, very sparsely punctulate throughout, extremely minutely so poste - 

 riorly, somewhat asperulately toward base, the first impression with 

 but few widely spaced coarse punctures, the second with still fewer, 

 the third impunctate. Length 2.25 mm. ; width 0.5 mm. California 

 (Los Angeles Co. — Pomona Mts.), — H. C. Fall picina n. sp. 



4 — Form slender, coloration as in asperula; head of the usual form, 

 nearly as long as wide, broadly rounded at base, the sides becoming 

 parallel for some distance behind the eyes; punctulation extremely 

 fine, sparse, not muck more distinct at base; antennae attaining the 

 middle of the elytra, moderately incrassate distally, rather slender 

 toward base, the two penultimate joints distinctly transverse, the first
