Encarsia angelica n. sp. 
Male. — Length, 0.74 mm.; expanse, 1.7 mm.; greatest width of fore- 
wing, 0.25 nun. . Pedicel as broad as long, less than half as long as joint 
1 of fnnicle; fnnicle joint 1 as wide as or slightly wider than pedicel, 
rounded at base, more truncate at tip, appearing swollen in compari- 
son with next joint; joint 2 a little longer than joint 1 and narrower, 
cylindrical; joints, 3, 4, and 5 each a trifle longer than its px^edecessor, 
otherwise resembling it. Terminal joint a little shorter than its prede- 
cessor, rounded at base and tapering to somewhat pointed tip. Thorax 
and abdomen smooth. General color brownish yellow, darker on pro- 
notum and anterior portion of mesoscutnm at sides of parapsides and 
inetanotum, and on dorsum of abdomen; a dark line between the eyes 
and under ocelli. Tegnlae brown: all legs uniform pale straw-yellow. 
Described from one male specimen reared from Aleyrodes on willow 
September 17. at Los Angeles, CaL, by Mr. D. W. Coquillett. 
Genus ASPIDIOTIPHAGUS Howard.

Fondle. — Antenna' S- jointed; scape long, slender; pedicel a little 
longer than its apical width; fnnicle joints 1. 2 and ;i increasing in 
width, but each approximating pedicel in length: elnb long, distinctly 
3-jointed. basal joint shortest, apical joints subeqnal, terminal joint 
pointed. Lateral ocelli equidistant from each other and margin of 
compound eyes. Parapsides of mesoscutnm widely separated, very 
narrow posteriorly, broadening out rapidly toward tegulae; mesoscu- 
telluni like that of Aphelinus, its scapulae longitudinally elongate and 
extending forward to lateral widening of the parapsides; metanotum 
very narrow. Abdomen short, broadly sessile and broadly rounded at 
tip. Spur of middle tibia' very slender, as long as the short first tarsal 
joint. Forewings long, narrow; Bub marginal and marginal veins sub- 
equal in length; postmarginal lacking; stigma] very slight and parallel 
with costa. situated at half the wing length and exactly opposite to the 
termination of thickening of hinder margin of wing, this being also 
the widest point of the wing; cilia of wing surface rather sparse, a 
clear rounded space immediately below stigma, and a narrow clear line 
around margin; marginal vein bristly; marginal cilia very long, longer 
than wing width, those on costal margin just beyond stigma nearly as 
long as those on hind margin. Hind-wings very narrow, with long 
marginal cilia and but one row of discal cilia on outer third: marginal 
vein ending abruptly and extending up apparently beyond costa. 
Differs from Coecophagus in wings and from Encarsia in antennae 
and wings.
