Cyphosticha. Meyrick, Proc. Linn. Soc. X. S. \\ 7 ales, p. fii (1907). - Type : C. f>yrochroma, Turner. 



Characters. - Head smooth. Antennas over 1, basal joint moderate. Labial palpi long, 

 curved, ascending, with appressed scales, terminal joint as long as second, pointed. Maxillary palpi 

 moderate, filiform, porrected. Middle tibia' elongated and thickened with dense scales; posterior tibiae 

 with row of bristly hairs above. Forewings very narrowly elongate lanceolate ; 3 sometimes absent, 

 6 and 7 sometimes stalked, 11 from near base. Hindwings about one half, linear-lanceolate, cilia 5; 

 3 sometimes absent, 5 and 6 stalked. 



The relationship of the three species placed here is at present obscure; they may be more nearly 

 allied to Acrocercops. 



Early stages unknown. 



Geographical distribution of species. — Indian and Australian regions.
