although at first sight resembling those of the silk-worm, are 



TiTt really quite different. 



In the coalescence of 

 the branches of ra- 

 dius of the fore wings 

 veins III3 and III^ 

 remain separate, 

 while in the Satur- 

 niina these are the 

 first branches to coa- 

 lesce. And in the 

 hind wings there is 

 no indication that 

 vein I becomes joined 

 to the base of vein 

 II as is shown to be 

 the case in the most 

 generalized S a t u r - 

 niina (Figs. 417 and 

 419). 



The members of

val state feed upon leaves, and protect themselves by mak- 

 ing a case of leaves within which they live (Fig. 439).

Melsheimer^s Sack-bearer, Cicinnus melsheimerii (Ci-cin'-

 The adult moth (Fig' 440) is of a reddish gray color, finely 

 sprinkled all over with minute black dots; there is a small 

 black spot at the end of the discal cell of the fore wings ;
