Ala posterior area costali venulis nullis gradatis; area 

 apicali serie venularum gradatarum, ramo obliquo cubiti 

 parallelo postcubito; area postcubitali simplici, angusta. 

 The following species is the type, 



On comparison with Cryptoleon nebulosus Oliv., type of the 

 genus Cryptoleon Banks, it is evident that it cannot be included 

 in the same genus. Cryptoleon can be readily differentiated 

 from this genus by the wing structure. The costal area has 

 many gradiform veinlets in both wings, in the anterior wing 

 nearly in its entire length. The apical area has only one series 

 of gradiform veinlets in both wings.
