204 BULLETIN UNITED STATES GEOLOGICAL SURVEY. 



ish-hyaline ; stigma oblong, pale brownish-gray ; subcostal cross- vein a 

 little distance back of the tip of the auxiliary vein. 



Rab. — Grafton's Retreat, near San Bernardino, Oal., in March. Three 

 males and six females. 



The ovipositor of the female has nearly straight, ferruginous valves, 

 smooth on the under side. Length 6-7 mm . 



Phyllolabis encausta n. sp.— Head gray ; antennae brown, two 

 basal joints yellowish; palpi brown. Thorax gray, the dorsum with a 

 brownish-yellow tinge ; knob of halteres infuscated. Abdomen brown- 

 ish-black ; in the female, the two last segments are remarkably turgid 

 above and below; upper valves of the ovipositor short, curved, dis- 

 tinctly serrate on the under side. Legs brownish-yellow, tarsi darker 

 toward the end. Wings subhyaline; veins brown, except at base and 

 near the costa, where they are pale yellow ; subcostal cross- vein close 

 by the tip of the auxiliary vein. Length 6-7 mm . 



Rab. — Lagunitas Creek, Marin County, California, April 15-20 ; San 

 Mateo, Cal., April 9. Four females. 



Trichocera trichoptera n. sp. — Antennae brown, second joint 

 slightly paler; thorax dull grayish-pollinose, without any distinct 

 stripes; halteres with a brown knob; abdomen brown above, yellowish 

 below ; wings subhyaline, immaculate ; veins very distinctly pubes- 

 cent ; venation in the main like Monogr., iv, tab. ii, f. 13, but the 

 discal cell smaller ; posterior cells 2-4 longer ; the cross-vein at the 

 proximal end of the fourth posterior cell is placed obliquely, and thus 

 does not correspond with its posterior end with the great cross-vein 

 (this may, however, be merely adventitious). Feet pale yellowish. 

 Length 3-4 mm . 



Rab. — Lagunitas Creek, Marin County, California, April 15. One 

 female. 



This is the only specimen of the genus Trichocera which I came 

 across in California. The species will be easily distinguished by its dis- 

 tinctly pubescent wing-veins. 



Section Y. — Anisomerina. 



Eriocera californica n. sp. — Male. — Antennae more than twice as 

 long as the body; basal joints reddish; flagellum reddish-brown, beset 

 on its under side with two rows of small spine-like bristles ; head red- 

 dish above ; palpi brown ; thorax brownish, with a grayish pollen, es- 

 pecially on the pleurae; three brown stripes on the dorsum, the inter- 

 mediate one geminate; a faint brownish stripe on the pleurae ; halteres 

 with a brownish knob ; abdomen brown, lateral edges yellowish; geni- 

 tals reddish ; legs reddish ; tips of femora and of tarsi brown ; wings 

 with a strong brownish-yellow tinge, more saturate in the costal cell ;! 

 five posterior cells. Length about 15 mm . 



Rab. — Marin County, California (EL Edwards). Two males.
