 Insect., fasc. 179, pp. 2, 3. — Clarke, 1963, Catalogue of the type specimens of 

 Microlepidoptera in the British Museum (Natural History) described by 

 Edward Meyrick, vol. 4, p. 6.5. 



Type-species. — Trepsitypa cardinata Meyrick, 1913. Original 

 designation and monobasic. 



Adult. — Forewings (fig. 29) with vein 10 arising from discal cell 

 at or very near origin of 11; 7 and 8 stalked for approximately half 

 their length; 3 and 4 stalked less than half their length. Hindwings 

 with 6 famtly present; discal cell shortened, extending less than half 

 the length of wing; 2 arising from outer fourth of cell. 



Female genitalia. — Ovipositor relatively long and slender; 

 posterior apophyses approximately twice the length of anterior pair. 

 Antrum and ductus bursae with thickened, densely papiUose walls 

 extending entire length to corpus. Corpus bursae completely mem- 

 branous, with a pair of deeply forked signa. 



Discussion. — The stalked condition of veins 7 and 8 in the primaries 

 immediately separates this subgenus from the other members of 

 Carposina as well as from all other genera of the family.
