 feeble, oue-third as wide as the disk; the latter transversely and ver^' mod-

 having a very small feeble impression near the base. Ehjlra at base distinctly

Santa Clara Co., 1 6 . 



The liftli ventral segment is broadly cmarginate in its 

 middle, three-fourths at apex, the oniargi nation being 

 broadly rounded and six times as wide as deep; in the mid- 

 dle there is a short and very broad porrected process at the 

 bottom of the notch, Avhicli is broadly and feebly sinuate at 

 its apex, each side of the emagination having elsewhere a 

 porrected fringe of short, robust, very closely-})laced spin- 

 ules, about eleven in number; sixth segment deeply cmargin- 

 ato at apex, the notch being parabolic in outline and sliglitly 

 "wider than deep, exterior angles slightly rounded; seventh 

 narrowly divided. 



This species is distinguished froin all the others in tliis 

 division of the genus by its rather large and very minutely 

 punctate head. Tlie anterior tarsi are rather strongly di- 

 lated and clothed beneath with very short, pale, densely- 

 placed i)apill;o.
