top of sacciilus and laying along its edge; dentate portion of harpe 

 smaller, but its base much more extended across disc of valva and 

 forming a strongly sclerotized dorsal lobe. Juxta elongate and 

 asymmetrical. Caidis very long and slender. Anellus, a broad ring. 

 Aedeagus narrow, attenuated towards top. Signum, a sclerotized 

 and dentate ridge. 



Female genitalia: Sterigma indefinite. Collicidum, a large sclerite, 

 dilated doAvnward, t\^^ice as broad along upper half as along lower; 

 inside this sclerite, a band, slightly tortuous and rather narrow, 

 protruding beyond the lower edge of the former. Ductus biu'sae 

 short. Cornuti, a large, elevated, and scobinate knob. 



Type species: Platypeplus erotias Meyrick, 1905 (figs. 58-59, 63-64). 



Apparently a modification of the Olethreutes stock, judging from 

 the tegumen part of the genitalia. The attachment of the valvae, 

 however, is somewhat Laspeyi'esiine, which must be due only to the 

 abnormal development of this part. 



Gatesclarkeana asynihetes, new species
