722 Coleopterolocjical Notices, VI. 



sparse!}' punctate, witli the usual inipunctate line wide toward the front; an- 

 tennne not as long- as the head and in-othorax, rather slender, gradually and 

 scarcely perceptibly incrassite, the tenth joint but slightly -wider tliaji long. 

 Proihomx very slightly narrower than the head, about as long as wide, nar- 

 rowly rounded but not at all angulate at apical fourth , the sides thence ob- 

 lique and straight to the base; apex broadly arcuate; disk convex, not coarsely 

 but deeply, very closely punctate. Elytra large and long, three-fourths longer 

 than wide, fully twice as wide as the prothorax, senii-circularly rounded be- 

 hind, very slightly wider behind the middle than at base; humeri broadly and 

 transversely exposed at base; post-scutellar impression broad and feeble, the 

 omoplates obsolete; punctures close, deep and moderately large. Abdomen 

 somewhat strongly shining, minutely, closely punctate, finely pubescent, the 

 legs moderate in length and very slender. Length 2.1-2.2 mm.; width 

 0.7-0.75 mm. 



California (near San Francisco and in Humboldt Co.); Nevada 

 (Reno). 



Evidently allied to nanus, but much larger, -with distinct 

 cephalic structure, denser sculpture, longer el3'tra and difl'erent 

 coloration. I have seen onl}' a single female from each of the 

 three localities. 



At each side of the front, near the point of antennal insertion, 

 there is a small pale impunctate spot of doubtful significance, but 

 possibl}^ a point where the condyle of the basal joint thins out 

 the upper surface; it is, however, at a considerable distance from 

 the antennal foramen, and does not appear to be connected in 

 auy vfay with that organ. 



47. A. aiiioeiius n. sp. — Moderately stout, somewhat shining, piceo- 

 testaceoiis, the head and abdomen frequently darker; elytra generally with a 

 broad and nul)ilate median fascia; pubescence of the head long but sparse and 

 inconspicuous, of the pronotum shorter, decumbent, pale cinereous, dense 

 and distinct, of the elytra similar but less dense. Head rather small, slightly 

 wider than long, transversely truncate but scarcely at all impressed at base, 

 the angles broadly rounded; eyes moderate, not very convex and not quite as 

 long as the tempora, the latter parallel and feebly arcuate, gradually curving 

 into the l)ase; punctures coarse, deep and only moderately sparse, the wide 

 median smooth line somewhat irregular; antenn:u not quite as long as the 

 head and prothorax, feebly incrassate, the tentli joint sub<iuadrate. Proihomx 

 very slightly narrower than the head, a])Out as long as wide, rather narrowly 

 but not angularly rounded at apical fourth, the sides thence oblique and straight 

 to the base; disk somewhat finely but deeply and densely punctate. Elytra 

 three-fourths longer than wide, twice as wide as the prothorax, circularly 

 rounded at apex, the sides parallel and feebly arcuate; humeri widely and 

 transversely exposed at base, rounded externally; scutellar impression very 

 broad and feeble, the omoplates obsolete; punctures rather fine and close-set.
