together almost quadrangular, their apices individually rounding and 

 exposing two stout curved hooks. 



Described from eight examples from San Francisco, California.

Paropuhpa arborea, n. sp. — Resembling Mexicana in form and 

 colour. Smaller and slenderer ihan /riscana. Pale castaneous. Length, 

 3.5 mm. 



Vertex very short, evenly rounding, margins parallel, nearly five times 

 as broad as long. Pronotum convex, elevated behind. Elytra long, 

 slender, the costa only weakly convex, venation distinct, usually two and 

 often three transverse nervures between the sectors, in the latter case there 

 are usually two complete sets of anteapical cells. 



Colour pale castaneous, traces of three fuscous points on anterior 

 margin of vertex, the apices of the claval nervures marked with light. 

 Sometimes the apical portion of elytra is faintly mottled with milky. 



Genitalia: Female segment short, slightly roundingly excavated on 

 the posterior margin, a pair of lateral plates appear beneath in one speci- 

 men. Male valve short, transverse, nearly parallel margined, plates long, 

 almost parallel margined, longer than their combined width, their apices 

 individually, roundingly pointed. 



Described from four examples from Colfax, California. Collected by 

 the author. 



Paropulopa Californica, n. sp. — Resembling interrupta in size and 

 form, slighily longer and narrower and with more definite dark nervures. 

 Length, 3 mm. 



Vertex slightly shorter and more evenly rounding than in interrupta, 

 especially in the female. The margin inclined to be thick, as in Mexicana. 

 Pronotum not as strongly pitted or as much depressed anteriorly as in 

 interrupta. Elytra moderately long and narrow. The costa only slightly 

 curved, venation strong and distinct on apical portion of corium. 



Colour : Pale straw, coarsely and irregularly irrorate with fuscous, 

 the nervures on apical portion of elytra almost entirely fuscous, on 

 anterior portion pale or milky. 



Genitalia : Female segment long, the lateral margins straight, the 

 posterior margin slightly roundingly emarginate from the sharp lateral 

 angles, the middle deeply notched. Male valve short, broad, posterior 

 margin broadly rounding. Plates extremely large, longer than their com- 

 bined width, their apices together broadly rounding.
