 latter apparently three-branched ; while in the Lasiocampid^ 

 cubitus appears to be four-branched. 



This superfamily includes the Bombycidce which are 

 represented in this country only by the Chinese Silkworm 

 and three families of native moths. These can be separated 

 by the following table : —

 C. The stalk of veins Vi and V2 of the fore wings separating 

 from radius before the end of the discal cell (Fig. 420, c. v.),
