MICROLEPIDOPTERA OP NEW GUINEA 
inwardly oblique moderate transverse dark brown streak, running from 
1 / i of dorsum to lower edge of cell at x / 3 of wing, top adjacent to an elongate 
moderate spot of orange-brownish suffusion in cell, almost reaching 
triangular costal spot; a small triangular dark fuscous spot on 3 / 4 of 
dorsum, a point on middle of closing vein; some four vertical dark brown 
strigulae on termen suffused with orange-brownish, second one on middle 
of termen, continued by a faint orange-brownish line with penultimate 
costal dot; a round spot of orange-brownish irroration in apex. Cilia pale 
golden-ochreous, a narrow interrupted dark fuscous antemedian line; 
apical third of cilia with a row of dark fuscous dots. Hind wing and cilia 
pale golden-ochreous, tinged brownish. 
Ovipositor elongate. Eighth segment moderately erect, cylindrical. 
Ostium wide, dorsal wall with a transverse thickened bar. Limen, simple, 
a thickened short-haired pad at each side. Ductus bursae rather short, 
wide, with strongly plicate wall, upper part cup-shaped, short-dentate. 
Bursa copulatrix small, spheroid, covered throughout with strong thorns 
with dilated bases, opposite opening of ductus bursae becoming long 
spines (Slide No. 8211 D). 
Lake Habbema, 3250 — 3300 m, August 20, 1938. One specimen. Related 
to C. reliquatrix Meyrick, from Java. 
TORTRICIDAE 
Older authors, especially those who specialised in the Palaearctic fauna, 
regarded the tortricoid group of Microlepidoptera, known at the time, as 
belonging to one single family, the Tortricidae. It was Meyrick who 
raised this group to the rank of a superfamil v under the name “Tortricina” 
and separated the families Phaloniidae, Tortricidae (including Ceracidae), 
Eucosmidae (= Olethreutidae auct.), and Chlidanotidae. 
This classification was accepted and for a long time used by many 
entomologists, the present author included. Lately, however, Meyrick's 
views were severely criticised. Especially his separation of the Tortricidae 
from the Eucosmidae was attacked and rejected by several authors, as, 
e.g., by Turner, by Janse, and recently by Obraztsov. 
The relation of these two tortricoid groups is indeed very close and 
there are no “absolute” characters available for their separation. Even 
the most trustworthy feature: the presence in the Eucosmidae of a cubital 
pecten (a pecten of hairs along the lower edge of the cell in the hind 
wings) is not reliable. A cubital pecten is present in several genera of the 
Tortricidae (as, e.g., in a new genus described below), while it is absent 
in some genera of the Eucosmidae. It is true that the tortricid genera 
possessing a cubital pecten in other respects are not closely related with 
the Eucosmidae. Still we are now satisfied that for a more natural classi- 
fication the two groups have to be united as one family, Tortricidae, and 
must be sunk to the rank of subfamilies under the names Tortricinae and 
Eucosminae.
