long as broad; marginal cells subequal; veins not sinuate; radial 

 cell large. 



Genitalia. — Male. — Anal valve long, slender, simple, a little longer 

 than forceps, posterior edge concave, pubescent; forceps long, 

 widening slightly toward apex, rounded at apex; posterior view 

 shows forceps thin and subspatulate apically, densely fringed with 

 hairs on inner margin. Female. — Genital segment moderately long, 

 dorsal valve longer than ventral, margin regular, both acutely pointed. 



Described from 12 males and females from Placer County, Cali- 

 fornia (paratypes), collected by A. Koebele on ArctostapJiylus pun- 

 gens, September and October; several from Marble Valley, California 

 (Koebele), July; Siskiyou County, California (Koebele); Oracle, 

 Arizona (Hubbard and Schwarz) ; Colorado (Gillette) ; Easton, Wash-

EUPHYLLURA ARCTOSTAPHYLI NEVEIPENNIS Schwarz. 



Euphyllura arctostaphyli var. neveipennis Schwarz '04:235. 



Form and structure similar to species ; color variable, as in species ; 

 wings snow-white, sometimes with brown spots on apical margin, 

 surface rather white-pulverulent in appearance, venation somewhat 

 obscured. Genitalia somewhat similar, but forceps with the inner 

 ridge and fringe of hairs much less conspicuous. 



Described from nine specimens from Placer County, California 

 (paratypes), collected by A. Koebele together with the typical speci- 

 mens of the species, and several from Marble Valley, California 

 (Koebele) ; Los Angeles, California (Koebele) ; and Pasadena, Cali- 

 fornia (Grinnel).

 Fig. 6. 



Euphyllura arbuti Schwarz '04: 237. 



Length of body 2.3 mm.; length of forewing 3.2; width of head 1.3. 

 General color reddish brown to yellowish brown, venter and legs

 claval suture. Body moderately large, robust. 



Head strongly deflexed, as broad as thorax or broader, rugose,

 genal lobes thick, slightly shorter than in arctostaphyli, not depressed 

 below vertex, a little lighter in color than vertex, very sparsely and 

 briefly pubescent on front margin. Antennae a little longer than in 

 preceding species, slender. Eyes very recessive. 



Thorax very broad and strongly arched, less rugose than vertex,
