Mylophila. 155 



with three obh'que silvery-white stripes, the costa being of this 

 colour also. The abdomen and hind-wings are yellowish-white, 

 darker in the male than in the female. The antennae are red- 

 dish brown. The costa, inner margin, and tips of the fringes 

 of the fore-wings are purplish-red in the male, yellow in the 

 female. 



The larva is light green, with a yellow lateral line and two 

 red streaks behind. It feeds on a variety of common trees, 

 and changes into a reddish-brown pupa, which is enclosed in 

 a dense boat-shaped cocoon. 



The Moth flies early in the evening, and, like Callarciia 

 pudica (Esper ; vide anted, p. 152) stridulates during flight. 



Concerning this species, Mr. Meyrick writes : — " Although 

 showing relationship to the group of Callimorpha and the exotic 

 family AgaristidcB (which also originate from Callimorpha), the 

 actual ancestry of this curious form is obscure." We abstain 

 from commenting on this rema^-kable utterance.
