MICROLEPIDOPTERA OE NEW GUINEA 
7 
Tegumen strong, rectangular. Uncus strong, top mostly broad. Socius 
small, pending. Gnathos mostly very strong, arms scobinate below. 
Transtilla unpaired, broad, scobinate at the sides. Valva moderate, simple, 
slightly elongate. Aedoeagus strong, often with a distal thorn. Cornuti, a 
sheaf on spines. 
Ostium cup-shaped. Ductus bursae narrow, long. Bursa copulatrix 
small, spheroid. Colliculum and cestum absent. Signum, a moderate thorn 
without capitulum. Ovipositor lobes rather narrow. 
Moths of moderate size and distinct facies: with elongate wings, with 
costa gradually curved, apex projecting, terinen moderately sinuate; often 
with the following characteristic markings: edge of basal patch, and 
anterior edges of central fascia and of costal patch forming parallel 
transverse bands; costal patch large, wedge-shaped, reaching almost to 
torn us; a dark small dot on end of cell. Correlated with the Asiatic 
Leontochroma Walsingham and 
perhaps also with Ulodemis Me y - 
rick, and, judging by the male 
genitalia, also with Adoxophyes 
Meyrick. Capua parorthota Mey- 
rick, 1928 (Ex. Microl., vol. 3, 
p. 453), from the Bismarck Archi- 
pelago, and Catamacta dihamma 
Diakonoff, 1941 ( Treubia , vol. 
18, pp. 416—417), from Borneo, 
belong to this genus, and possib- 
ly also the Australian Aniso- 
gona placoxantha Lower, 1896

Fig. 209: Choanograptis didyma Meyrick, v ° 1- 20, P* *60), and Acroceu- 
female, wing neuration and head. thes oxygranwiana Meyrick, 
1881 (Proc. Linn. Soc. N.S. Wa- 
les, vol. 6, p. 460); however, we do not possess any material of the 
two last mentioned species at present, to make sure.
