198 Records of the Indian Museum. [Vol. Ill, 



hyaline with brown cross-veins, stigma yellow, diffuse, but con- 

 spicuous. Fore and hind wings of nearly equal length, but the hind 

 wing somewhat narrower. In the cubito-anal loop of the fore wings 

 there is but one cross-vein beyond the level of the cubital fork. 

 Legs yellow, with hoary hairs intermixed with slender black spines. 

 Abdomen wanting. 



I judge from the description that the (?) Idricerus albardanus 

 of Mclyachlan from Mesopotamia, belongs also to this genus.
