MICROLEPIDOPTERA OF NEW GUINEA 
shaped cell of the fore wing. Actually, the present genus belongs to the 
subfamily Hypertrophinae, and is closely allied with Oxytropha Dlakonoff, 
from which genus it chiefly differs by shorter labial palpi, with the median 
segment not reaching the bases of the antennae, and with the terminal 
segment very short (instead of being longer than the half of the median 
segment, as in Oxytropha)-, furthermore, by the ciliate ante nn ae of the 
male, by the inferior, instead of a posterior, ocellus, and by other minor 
differences. This is the first record of the subfamily outside the Australian 
region. 
Polygiton pachypus spec. nov. (figs. 739, 740, 744, 750) 
Tmyyr; = thick, naic, = foot 
O, $ 15.5 — 16 mm. Head and thorax light yellowish-ochreous, the latter 
becoming ochreous-whitish above. Antenna pale yellowish-ochreous, 
ringed with blackish, rings becoming paler towards base. Palpus ochreous 
in male, pale yellowish-ochreous slightly mixed with fuscous in female. 
Abdomen dark fuscous-grey in male, blackish-fuscous, on basal half 
becoming whitish-fuscous in female. Legs: anterior black, tarsus whitish 
with a broad subapical blackish ring, median dark fuscous, tarsus with 
whitish basal half, posterior leg dark fuscous, basal half and apical tuft of 
tibia and median third of tarsus whitish. Fore wing broadly subtriangular, 
costa moderately curved throughout, apex somewhat obtusely pointed 
in male, more pointed in female, termen sinuate, little oblique. Greyish- 
fuscous, partially suffused with fulvous-tawny, irrorated with dark 
fuscous. A large yellowish-white basal spot moderately suffused with 
deeper ochreous-yeflow, extending over basal third of wing, margin 
moderately convex, almost vertical, edged with a suffused fulvous-tawny 
streak; a semioval dark fuscous patch occupying basal fourth of costa, 
edge, except along costa, rather suffused with fidvous-tawny, on base of 
wing suffused with light ochreous-yellow ; a small elongate spot just 
beyond middle of costa, in female extended across wing so as to form a 
subquadrate small patch ; in both sexes a crescentic whitish-yellow mark 
in centre of disc below preceding spot, open above, in female indistinctly 
connected with the costal spot posteriorly; these markings followed by a 
transverse ill-defined streak of fulvous-tawny suffusion; a yellowish-white 
dot on costa at 1 / 6 ; shining leaden-purple scales arranged as follows: 
a dot in centre of the dark costal patch ; another dot below costa just 
beyond subapical whitish dot ; two transverse streaks : at 1 / 2 and at 3 / 4 , 
tolerably direct, slightly outwards-convex ; third more distinct streak 
from 3 / 4 of costa outwardly concave to before termen below apex, thence 
outwardly convex, tolerably parallel to wing edge, submarginal, to tornus; 
purple streaks more or less separated on upper half of wing by dark fuscous 
suffusion ; dark fuscous irroration forming an ill-defined longitudinal narrow 
streak from before apex to below lower angle of cell, interrupted by
