MICROLEPIDOPTERA OF NEW GUINEA 
55 
posteriorly. Greyish-lilac, rather regularly transversely strigulated, and 
blotched with dark brown which is broadly edged with light ochreous, 
colouring giving a rather regular marbled and irrorated effect. Basal patch 
indicated by a narrow dark brown line, straight and oblique above, curved, 
less oblique, and sinuate below, with a rounded moderate patch in middle, 
and by a short blackish suffusion of base of dorsum neither reaching base 
of wing nor fold; central fascia indicated by a small mark at x / 4 of costa 
and a little oblique, strongly clavate irregular transverse band from 
middle of dorsum to below costa at 2 / 5 ; costal patch as in male, costal dots 
and a rounded spot on top of costal patch darker, blackish -brown ; an 
irregular interrupted sinuate dark brown striga from below top of patch 
to tornus; apical and terminal markings about the same as in male, but 
dark brown. Cilia greyish-fulvous, becoming more mixed with pale ochreous 
towards tornus, in tornus greyish ; a basal row of dark fuscous blotches. 
Hind wing and cilia somewhat darker than in male; cilia with two pale 
lines. 
Ostium broad. Limen, a broad band interrupted in middle. Colliculum 
strong, moderately long, fused with ductus bursae which is sclerotised 
throughout, forms a thick-rimmed longitudinal split along lower two- 
thirds, and has a rounded projection in bursa. Bursa copulatrix erect- 
ovoid, without signum (Slide No. 614 D, allotype). 
Mist Camp, 1800 m, January 11, 1939 (holotvpe, male), January 16, 
1939 (allotype, female). Two specimens. Allied to preceding. Female insect 
in this and preceding species reminds much of an Epagoge, but differs from 
that genus by the position of vein 2 in fore wing which originates from 2 / 3 
of lower edge of cell. 
Rhomboceros iridescens spec. nov. (fig. 262) 
13 mm. Head with a flattened tuft on vertex, face excavate, a flattened 
tuft below; deep bronze-brown, vertex fuscous mixed with ochreous- 
greyish. Palpus brown, terminal segment dark brown, extreme tip pale 
ochreous. Antenna slightly serrate, greyish, ringed with blackish-brown, 
basal seventh dilated by scaling, blackish below. Thorax dark fuscous 
(damaged), abdomen dark greyish-fuscous, anal tuft lighter. Legs fuscous, 
anterior darker. Fore wing without costal fold, edge of basal patch below 
costa with roughly projecting scales, smooth on edge of costa, roughly 
projecting again on under surface of wing; costa abruptly strongly curved 
at base, straight posteriorly, curved before apex, apex subacute, termen 
hardly concave above, rounded beneath, rather oblique. Basal patch 
moderate, roughish, ferruginous-brown, mixed with bright ochreous, edge 
almost straight, oblique, with a ridge of raised blackish-brown scales; 
costal patch extending along third fourth of costa, conspicuous, semi- 
circular, deep ferruginous-brown, including a postmedian rounded dark 
grey dot below costa; top of costal patch not reaching to middle of disc, 
connected by a somewhat curved irregular moderate deep ferruginous-
