MICROLEPIDOPTERA OF NEW GUINEA 
brown and fulvous-brownish. Basal patch moderate, ferruginous-brown, 
edge slightly convex, somewhat oblique, a broad ferruginous-brown fascia 
originating from its middle, running along lower edge of cell, with two 
angular projections below, wdiich are connected with dorsum by a fulvous 
suffusion; this fascia is narrowed on lower angle of cell, and connected 
with top of a large invert-triangular suffused patch from below' costa, 
which is connected above with costal edge by four short projections and 
reaches from 3 / 6 of wing to before apex; two narrow oblique ferruginous- 
fulvous transverse lines on 2 / 5 of costa, connected along upper edge of cell 
by a ferruginous longitudinal streak; a row' of rounded fulvous dots along 
dorsum, in tomus and along lower part of termen; preterminal area 
suffused with bright ochreous-fulvous. Cilia brownish -fulvous (damaged). 
Hind wing pale ochreous, very faintly dotted with greyish; cilia whitish. 
Genitalia much like those in the preceding species. Hook of uncus more 
rounded. Hook of gnathos larger. Transtilla more dentate. Valva longer 
(Slide No. 494 13). 
Sigi Camp, 1500 m, February 24, 1939. One specimen, somewhat rubbed 
off but distinct by typical markings. Allied to preceding.

The following species (females) doubtlessly belong to the present genus, 
but differ slightly from the genotype, T. periorma (Meyrick, 1910) by 
having veins 3—5 in fore wing only slightly approximated, and by having 
veins 3—4 in hind wing separate.

18.5 mm. Head pale ochreous, tinged pale greyish. Antenna greyish- 
fuscous, scape pale ochreous. Palpus light ochreous, median segment with 
a very oblique subbasal transverse band, a longitudinal patch towards 
apex above; apical edge and terminal segment throughout fuscous-grey. 
Thorax pale tawny-greyish, tegida wbitish-ochreous, suffused towards 
apex with light ochrcous-brownish. Abdomen dark fuscous-grey, anal tuft 
and venter light ochreous, sides with long light ochreous hairs. Legs pale 
yellowish-ochreous. Fore wing elongate-subovate, dilated, costa moderately 
curved anteriorly, straight in middle, more curved towards apex, apex 
somewhat curved, rather pointed, termen strongly sinuate, rounded and
