maculate in middle and on hind margin conspicuously so, semi trans- 

 parent, a little more than twice as long as broad, broadly rounded at 

 apex and apical half of wing distinctly narrowing toward apex; first 

 marginal cell larger than second; radial sector long and curved ; ptero- 

 stigma long, large at base. 



Genitalia. — Male. — Genital segment very large, about half as large 

 as rest of abdomen ; forceps moderately long, stout, roundly acute at 

 tip; anal valve very large, larger than forceps, with a large, lobate 

 protuberance on hind margin; pubescence short. 



Described from one male from Claremont, California (Crawford), on 

 OeanotJius crassifolius. This form is manifestly distinct from A. 

 ceanothsB, but was taken on the same tree and together mth the 

 specimens of the other species. 



Type in author's collection.

Figs. 60, 234, 286, 446. 



Length of body 1.9 mm.; length of forewing 2.4; width of head 

 0.88. General color light brown, abdomen darker. 



Head not strongly deflexed, not quite as broad as thorax, punctate. 

 Vertex with a fovea on each side of median Ime, arcuate on posterior 

 margin, with a swollen area on each side of front ocellus. Genal 

 cones short, rounded, broad, contiguous at base, divergent, somewhat 

 descending from plane of vertex. Anteimse rather short, slender. 



Thorax not strongly arched, coarsely punctate. Pronotum rela- 

 tively rather long, with lateral fovese prominent; prsescutum short. 

 Wings small, slender, about two and a half tunes as long as broad, 

 hyaline, maculate apically, roundly acute at apex; marginal cells 

 subequal; radial sector long, straight; pterostigma long, narrow, 

 yellowish. 



Genitalia. — Male. — Genital segment large, rounded; forceps mod- 

 erately short, simple, curved ; anal valve obtriangular, large, with the 

 long axis anterior; pubescence sparse. Female. — Genital segment 

 much longer than rest of abdomen, which is usually rather short, 

 acute at apex; dorsal valve longer than ventral. 



Described from one male and seven females collected at Claremont, 

 California (C. F. Baker); several from Los Angeles, California 

 (Koebele), (Coquillett), on Ceanothus sp., in May.
