Psyche 
[June 
with outer series, not so strongly zig-zagged. Anals not 
forked, run in a smooth curve to margin of wing. Jugal 
lobe prominent, one jugal vein present. Hind wing: 
jugal process small, costal area narrow. MP fused with 
Rs for a short distance, basal Banksian cell unusually 
large. Two gradate series; Psm weakly differentiated 
from inner gradates, not so strongly zig-zagged as in 
fore wing. Psc merges with outer gradates as in fore wing. 
Generotype: Pimachrysa grata n. sp. 
This genus is similar in its venation to Triplochrysa 
Kimmins, from which it may be distinguished by its 
having the first intra-median cell closed apically by a 
cross-vein, and by the occurence of only two gradate series 
in both wings. 
Pimachrysa grata n. sp. 
Figs. 1-5 
Head straw yellow, a shallow groove between bases of 
antennae black; maxillary and labial palpi pale at base, 
penultimate segment fuscous, last segment black. Anten- 
nae stout; scape pale, with medial, ventral, and lateral 
surfaces infuscated distally; condyle appears as dark 
longitudinal line on medial surface; pedicel short, black; 
flagellum black. Pronotum wide, anterior margin straight; 
whitish yellow with three fuscous stripes slightly con- 
vergent anteriorly. Meso- and metanota yellow, scuta 
infuscate posterolaterally. Cervical sclerites black; meso- 
and metapleurae bright yellow, with many areas fuscous. 
Legs ivory white; femora with a wide fuscous band 
before the knees. Tibiae slightly infuscated on lateral 
surface just beyond knee; tarsi a uniform light brown, 
last segment much darker than preceding. Legs uniformly 
clothed with short, dark, setae.
