Metembia flava Ross, new species 
(Figures 1 to 5) 
Holotype male (on slide): Color — pale yellow throughout, 
head and thorax somewhat darker, wings light brown, abdom- 
inal terminalia with tenth tergite and basal segment of left 
cercus tan. Dimensions — length 7.5 mm.; fore-wing length 
3.57 mm., breadth 1.0 mm. 
Head (fig. 1) with form as illustrated, very weakly pigmented 
throughout except the mandibles which have golden-brown 
apices. 
Wings with hyaline stripes very broad, margins ragged. R ± 
nearly attaining wing apex, slightly curved toward R 2+3 and R 4 . 
Hind basitarsi (fig. 5) with two conspicuous sole-bladders. 
Terminalia (figs. 2 to 4) with left tergal process (10 LP) 
small, short; form as illustrated (fig. 3). Right hemitergite 
(10 R) with a cone-like caudal projection (10 RPi) which 
terminates as a minute sclerotic point; secondary process 
(10 RP 2 ) represented as a long, longitudinally folded, submem- 
branous area closely paralleling inner side of 10 L and terminat- 
ing as a small rounded lobe. Hypandrium (H) scarcely pig- 
mented, outline inconspicuous, quadrate; caudally produced 
medially as a short, broadly rounded lobe (HP). Composite
