MICROLEPIDOPTERA OF NEW GUINEA 
moderate or large, pending. The cestum is moderate or absent. In this 
group fit rather well the remaining genera of the tribe, except the rather 
separated group of Choanogra/ptis, and the allied genera (this group will 
be dealt with in the second part of this paper).

This genus is an intermediate between the present tribe and the Zaco- 
riscini. Socius not separated: a row of bristles above base of gnathos 
(cf. l.c. fig. 31). Dorsal coremata of seventh sternite in male (scopa dorslis) 
extremely large, formed by dense broad scales which in situ (studied with 
a magnification of 0 — 10 times) appear as a shining smooth cap over the 
anal segment. Corethrogyne absent.

Distribution: North New Guinea, Hunsteinspitze, 1350 m. 
$ 22 mm, allotype. Palpus with median segment strongly triangularly 
expanded by roughly projecting long scales above. Fore wing elongate- 
subovate, rather broad, broadest in middle; costa strongly curved an- 
teriorly, slightly curved posteriorly; apex little rounded, slightly pro- 
jecting; termen slightly concave above; broadly rounded and projecting 
beneath. Costal half of basal patch densely suffused with dark ferruginous- 
grey, space between this and central fascia broader than in male, without 
a brownish transverse strigula, pale ochreous. Otherwise similar to male. 
Limen narrow, in middle membraneous. Ostium cup-shaped. Colliculum 
very short. Cestum reduced to a terminal rather weak part, terminal fold 
ill-defined. Signum moderate, curved, short-dentate (Slide No. 452 D).

Head with loosely appressed dense scales. Antenna moderately ciliatein 
male, minutely pubescent in female. Ocellus posterior. Proboscis rather 
weak. Palpus moderate or moderately long, porrect or slightly sub- 
ascending, median segment mostly somewhat sinuate, strongly dilated 
posteriorly by roughly projecting scales above and beneath, often forming 
a small tuft towards apex beneath; sometimes rather slender, less sinuate, 
with appressed scales below, roughly scaled towards apex above, terminal 
segment short, subacute, sometimes almost concealed. Thorax with a 
more or less distinct double posterior crest. Fore wing elongate or sub- 
triangular, seldom with a costal fold in male, costa often ciliated through- 
out, or with small projecting patch of cilia in middle, sometimes smooth.
