Labial palpi absent. Maxillary palpi absent. Posterior tibioe 

 clothed with long hairs. Forewings with vein 1 simple, 3 some- 

 times absent, 4 absent, 5 absent, 7 to costa, 8 sometimes absent, 11 

 from before middle. Hindwings |-|, narrow-lanceolate, cilia 3-5 ; 

 cell open between 2 and 5, 3 absent, 4 absent. 



Probably a development of the Nematobola group, but no 

 immediate connection can be made out. The genus is of some

 have been overlooked elsewhere. The peculiar larval habits may 

 be compared with those of Nematohola.
