The species of this distinct genus are known to prey upon 

 ZygcBuid and Pyi-alid moths, and in tlie United States, Ashmeail 

 has bred one from a species of Apatara ; they spin a blackish 

 cocoon within that of their host and closely adherent thereto {cf. 

 Bridgman, E. M. M. 18S9, p. 185) ; but the Indian species appear 

 to construct pendulous cocoons, a habit hitherto unobserved in 

 this genus. Walker has described one species, which he doubt- 

 fully ascribes to this genus from Japan, under the name C. lateipes 

 (Cistula Entom. i, 1874, p. 307); the type is now lost.
