(cf 9, Ceylon, Bhotan, Natal, Venezuela, French Guiana).— Clarke, 1955,<br />

Catalogue . . . Microlepidoptera . . . Meyrick, vol. 1, p. 304.<br />

Distribution: Recorded by Meyrick from Ceylon, India, South<br />

and West Africa, South America, Bismarck Is., Northeast Australia,<br />

China, Malaya. Probably several distinct species and subspecies<br />

are concerned.<br />

Material examined: Luzon, Mt. Makiling (Baker), 3 cf ,<br />

genit. slide<br />

5285; 1 9, genit. slide 5272 (USNM). Luzon, Benguet Subprov.,<br />

Klondyke, 800 ft., 16.III.1912 (A.E. Wileman), 1 9 (BM).<br />

Male genitalia: Tegumen, a broad and simple plate with a rounded<br />

edge. Tuba analis as long as tegumen, sclerotized, with a ventral<br />

split, extended far capitad as a sclerotized oval plate, so forming a<br />

large subscaphium. Vinculum, a narrow ring. Saccus short and<br />

pointed. Valva elongate, strongly concave longitudinally, ventral<br />

angle pointed. Cucullus long, finger-shaped. Processus basilis moderate.<br />

Juxta small, oval, du^cted backwards (rostrad). Anellus<br />

short, tubular. Aedeagus slender, moderately long, apical third<br />

attenuate, edge with sparse serrations.<br />

angles. Ostium, a simple, rather wide funnel. Colliculum indicated,<br />

a hyaline tube. Ductus and corpus bursae simple.<br />

Ischnuridia Sauber, 1902<br />

Ischnuridia Sauber, 1902, in Semper, Schmetterlinge Philippiuischen Insein,<br />

vol. 2, p. 704—Fletcher 1929, Mem. Dept. Agric. India, Ent. ser., vol. 11,<br />

p. 119 (Lyonetiidae?)<br />

Type species: Ischnuridia virginella Sauber, 1902 (Philippine Is.).<br />

This mysterious genus has been attributed by Meyrick to the family<br />

Lyonetiidae, according to his unpublished notes, preserved in the<br />

British <strong>Museum</strong> (Natural History). Fletcher followed him (1929)<br />

but recorded the family name with a question mark. Apparently<br />

the species has never been restudied.<br />

With the kind help of Dr. Heinz Schroder, Senckenberg <strong>Museum</strong>,<br />

Frankfurt am Main, Germany, I was able to place the insect<br />

exactly. The unique type specimen of the type species is preserved<br />

in that museum. I was allowed to dissect the distal portion of the<br />

abdomen, while Dr. Schroder kindly provided me with a photograph
