MICROLEPIDOPTERA OF NEW GUINEA 
Hermenias serrula spec. nov. (fig. 350) 
$ 17—18 mm. Head light ochreo us-brown i sh , face whitish. Antenna dark 
fuscous. Palpus moderately long, somewhat curved; pale ochreous, basal 
segment and median segment except upper edge and apex more or less 
suffused with blackish-fuscous. Thorax anteriorly fuscous-tawny, in middle 
blackish-fuscous, apical fourth whitish-ochreous, tegula whitish-ochreous, 
basal half fuscous-tawny. Abdomen pale greyish -ochreous-whitish. Legs 
whitish, anterior and median tibia and tarsus blackish -fuscous, pale 
ringed. Fore wing elongate, rather narrow, dilated, costa curved towards 
extremities, straight in middle, apex moderately pointed, termen faintly 
rounded, oblique. Pale ochx-eous, dorsal third suffused with light ochreous- 
brown or fulvous -brown, costal two-thirds densely suffused with dark 
fuscous, markings fuscous-black. Anterior half of costa with a row of small 
blackish dots of inequal size, some of them produced across wing by short 
suffused transverse strigulae, largest at 1 / 4 ; posterior half of costa with 
six somewhat suffused larger subtriangular clots, ultimate dot largest, 
rounded, apical; a longitudinal series of fuscous-black discal markings, 
faintly edged below with pale ground colour; these markings shaped as 
follows: an erect-ovate inwardly oblique transverse spot beyond base, 
not reaching dorsum, extending well above fold; another similar patch 
larger, more inwardly oblique, traversed in middle by fold, reaching below 
fold halfway towards dorsal edge, sometimes upper half (above fold) 
obliterate; third dark marking along fold, hardly reaching above second 
marking, from slightly before middle of wing to before end of cell ; this 
third marking elongate-triangular, with anterior edge vertical, upper edge 
horizontal, lower angle of marking halfway between fold and dorsum, 
posterior angle of marking continued by a moderate gradually curved 
semicircular streak, being concave above, encircling lower angle of cell from 
below, and reaching posteriorly well beyond this angle; a transverse 
moderate vertical blotch on end of cell, sometimes interrupted in middle; 
often abovementionecl discal markings less definite, more or less inter- 
connected by dark fuscous suffusion, so as to form an irregular longitudinal 
streak with strong serrate lower edge; dark fuscous suffusion of upper 
part of wing, becoming denser below middle third of costa and towards 
apex, becoming glossy -bronze in apex; a faint irregular sinuate streak of 
still darker blackish-fuscous irroration before termen, more or less con- 
nected with fuscous-blackish suffusion along termen. Cilia sordid pale 
ochreous, tips grey around apex; a blackish -fuscous interrupted ante- 
median band. Hind wing pale grey, suffused with light fuscous except 
towards base; cilia concolorous. 
Lirnen, a moderate subovate plate, broader than in H. conglomerata 
spec, nov., with pointed extremities. Cestum with a few small subchitinous 
folds. Bursa copulatrix small (Slide No. 792 D, holotype).
