cate at tip; eyes small and ])voniiiient; antennic rather short, not as long as the 

 head and prothorax, slender, feebly i ncrassate toward tip, the penultimate joints 

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

 the sides convergent anteriorly and feebly arcnate throngh<mt, broadly rounded 

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

 snbequally 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, snbparallel 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.'2-2A mm.; width 0.85-1.0 mm. 



California (Los Angeles Co.). 



The t3'pe has the fifth ventral segment short, broadh^ trapezoidal 

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

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

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

 seems to be wholly congeneric in structural characters. Three 

 specimens. 



DASYTASTES n. gen. 



I have applied this name to certain small species resembling 

 Dasytes 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 abruptl}' defined mar- 

 ginal rugose area, which constitutes so constant and characteristic 

 a feature in Dasytes as limited above. In addition to this it may 

 be stated that the antenni>^ 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: — 



Body uniformly black or piceous-black in color. 

 Elytra! vestiture cinereous throughout. 

 The pubescence short. 



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



bicolored 1. cataliiiae 



Head large; sides of the pronotum evenl}^ convex and declivous; legs 



pale rufo-ferruginous throughout 2. reilliSSUS 



The pul)escence long, fulvo-cinereous; legs bicolored 8. otiosus 



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

 ward base and at the apex 4. dispar 



Bwly bicolored, the head and prothorax pale and rufous.
