 latter apparently three-branched ; while in the Lasiocampidae 

 cubitus appears to be four-branched. 



This superfamily includes the Bombycidoe 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 : — 



A. Vein V 2 of the fore wings arising midway between veins V! and 



V 3 . p. 340 . Bombycidoe. 



AA. Vein V 2 of the fore win^a arising nearer to vein Vi than to vein 

 V 3 . 

 B. Hind wings with two anal veins. 

 C. The stalk of veins Vj and V 2 of the fore wings separating 

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

CC. Vein Vi of the fore wings separating from radius beyond the 

 apex of the discal cell. 

 D. Veins Vi and V a of the hind wings joined to radius by a dis- 

 tinct Stalk (Fig. 417, C. V.). p. 343 ClTHERONIIDiE.
