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

really quite different. 
In the coalescence of 
the branches of ra¬ 
dius of the fore wings 
veins III, and III 4 
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 Satur- 
niina (Figs. 417 and 
419).

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;
