cate at tip: eyes small and prominent; antennae rather short, not as long as the 

 head and prothorax, slender, feebly incrassate toward tip, the penultimate joints 

 slightly wider than long. Prothorax scarcely more than one-half wider than long, 

 the sides convergent anteriorly and feebly arcuate throughout, broadly rounded 

 into the base, the basal angles obsolete; apex nan-ower than the base, the two 

 subequally and distinctly arcuate; lateral edge finely serrulate and with a 

 short dense and distinct fringe; disk rather strongly and closely punctate, 

 broadly and abruptly reto-rugose laterally, the rugose area more sparsely pu- 

 bescent, not delimited by an impressed line. Elytra not quite one-half longer 

 than wide, barely one-third wider than the prothorax, subparallel and nearly 

 straight at the sides, the apex obtusely rounded; disk finely and rather closely 

 punctate. Under surface and legs densely clothed with short even cinereous 

 pubescence. Length 2.2-2.4 mm.; width 0.85-1.0 mm. 



Cfilifornia (Los Angeles Co.). 



The type lias the fifth ventral segment short, broadly trapezoidal 

 and rather broadly truncate at tip. The tibite and tarsi appear 

 to be very slightly pieescent occasionally. This is a very remark- 

 able species in the nature and disposition of the vestiture, but 

 seems to be wholl}' congeneric in structural characters. Three 

 specimens. 



DASYTASTES n. gen. 



I have applied this name to certain small species resembling 

 Das3'tes quite closely in general organization, but differing invari- 

 ably and radically in having the entire disk of the pronotum sim- 

 ply punctate and devoid of all trace of the abruptly defined mar- 

 ginal rugose area, which constitutes so constant and characteristic 

 a feature in Dasytes as limited above. In addition to this it ma^' 

 be stated that the antennse are shorter as a rule than in Dasytes, 

 and are more definitely incrassate toward apex. 



The six species known to me may be thus defined in brief: — 



T 



Body uniformly black or piceous-black in color. 

 Elytral vestiture cinereous throughout. 

 Tlie pubescence short. 



Head small; sides of the prothorax broadly subexplanate ; legs feebly 



bicolored 1. catalinae 



Head large; sides of the pronotum evenly convex and declivous; legs 



pale rufo-ferruginous throughout 2. reiuissus 



The pubescence long, f ulvo-cinereous ; legs bicolored 3. otiosiis 



Elytral vestiture dark and inconspicuous, becoming paler and coarser to- 

 ward base and at the apex 4. diiiipar 



Body bicolored, the head and prothorax pale and rufous.
