MICROLEPIDOPTERA OF NEW GUINEA 
73 
furcate at base, lc strong throughout, cell much narrowed anteriorly, 
edges almost touching each other along the basal J / 4 ; 2 from before angle, 
3 remote from angle, 3 — 6 separate, tolerably parallel and equidistant, 7 to 
costa, 8 out of 7 at middle, 9 out of 7 at one-fourth, 11 from beyond 
middle. Hind wing 1 /' 2 , lanceolate, with a costal shoulder, cilia 3; 2 — 6 
separate, tolerably parallel, distances between these veins gradually 
becoming smaller posteriorly, 6 and 7 closely approximated at base. 
Genotype Melaneslhes disema spec, nov., male. 
An interesting novel form, structurally correlated only with Agonismus 
Walsingham, from Hawaii, but widely differing in the shape of the 
labial palpi. No other genera of Cosmopterigidae, except these two, have 
veins 9 and 8 both stalked with vein 7. 
Melanesthes disema spec. nov. (figs. 615, 625) 
Si = two, orj/jut = mark 
15 mm. Head, palpus, scape of antenna and thorax fuscous-black, 
slightly tinged purplish, flagellum of the antenna sordid pale ochreous 
finely dotted with blackish, less than its third fourth black, the apical 
third snow-white. Abdomen dark fuscous. Legs fuscous-blackish, paler 
towards the base, tibiae and all segments of the tarsi with white rings, 
posterior leg also with a median w hite ring on the tibia, and a small dot 
on the apex of the femur, spurs snow-white. Fore wing lanceolate, costa 
very gently curved, apex acute, termen very oblique. Bronze-fuscous- 
black, markings white, faintly tinged yellowish, rather well-defined. A 
slightly inwards-oblique transverse fascia from 1 / 5 of the costa, gradually 
becoming moderately dilated below, with the anterior edge minutely 
serrulate, its base on the dorsum almost rounded; a transversely ovate 
moderately inwards-oblique dot on the dorsum at 2 / 3 of the wing length, 
reaching halfway across the wing. Cilia grey-fuscous, rather dull. Hind 
wing light fuscous-bronze, becoming subhyaline towards the base and the 
basal part of the costa, cilia grey-fuscous, along the basal half with faint 
green opalescense. 
Tegumen narrowed, at the base tightly soldered with the valvae proper. 
Uncus either asymmetrical or damaged in the type specimen; strong, 
bipartite, right part short, pointed (broken?), left ending in a tortuous 
filament. Valva entirely separated in a dorsal valva proper of the usual 
elongate shape, densely and finely bristled, and in a strong sacculus which 
is narrow', curved, with a twisted, flattened and dilated top. Anellus, a 
small plate. Anellus process very large, long, slightly curved, densely 
bristled, on a slender stalk. Vinculum, a transverse band. Aedoeagus 
slender, long, sinuate, narrow and curved posteriorly. (Slide no. 1072 D, 
type.)
