MICROLEFIDOPTERA OF NEW GUINEA 
63 
grey along middle. Hind wing snow-white, somewhat glossy, a blackish- 
grey marginal line in apex and along termen, broadest above, very narrow 
below, its inner edge suffused and preceded by black irroration, before 
apex reaching halfway towards cell. Cilia snow-white, basal third with 
small groups of grey scales in apex and along upper half of termen. 
Genitalia as in preceding, but with uncus subquadrate, top less rounded, 
distinctly emarginate. Socius only with four-five bristles. Gnathos very 
strong, hook long, broad. Transtilla and peniculus approaching those in 
auripes spec. nov. Juxta stronger corrugated. Vinculum more narrowed 
below. Aedoeagus with apparently shorter point (Slide No. 352 D). 
Sigi Camp, 1500 m, February 20, 1939. One specimen. 
Chionothremma combusta spec. nov. (figs. 47, 53) 
? 18 mm. Head, palpus and scape of antenna bright fulvous, terminal 
segment of palpus darker, infuscated at base. Thorax white, bright 
fulvous anteriorly. Abdomen whitish-ochreous, venter light ochreous, 
corethrogyne large, jet-black. Legs fulvous-ochreous. Fore wing rather 
narrow, costa gradually curved anteriorly, less curved posteriorly, apex 
rounded, termen straight and vertical above, broadly rounded beneath. 
Fore wing snow-white; base of costa with a short bright fulvous streak, 
posterior -/ 6 of costa with a narrow jet-black streak, somewhat dilated 
around apex, continued along termen in a series of five triangular black 
dots on veins, connected by a narrow marginal black line; a faint pale 
citric-yellow terminal suffusion, reaching one-third towards cell. Cilia 
white (imperfect). Hind wing white, a blackish-grey suffusion in apical 
seventh of wing, continued along upper part of termen, very narrow below 
and reaching to anal angle. Cilia snow-white. 
Lirnen moderately broad, lateral emarginations narrow, lateral pro- 
jections moderate, acute, with broad base. Ostium cylindrical. Cestum 
narrow, coiled terminally, terminal fold long. Signum broad. Anal 
segments weak (Slide No. 353 D). 
Mist ( amp, 1800 m, January 17, 1939. One specimen. The colouring of 
the hind wing suggests that this may be the other sex of the peeeding 
species, caelestis', however, the differences are so great that without 
additional material we prefer to regard this female specimen as belonging 
to a distinct species. 
Chionothremma ocellata spec. nov. (figs. 43, 64, 72)
