Under Side. Tongue indistinct. Breast and legs red brown. Abdomen and posterior wings clay- 

 coloured. Anterior ones brown orange, without any marks or lines thereon. Wings a little dentated ; 

 especially in the anterior wings. 



The larva of this insect is long, smooth, and shining, of a black colour, with eight 

 longitudinal continuous yellow lines, with the base of the legs and a spot on the neck red. 

 When alarmed it throws up its head and tail into the air. From the structure of the larva 

 it is therefore nearly allied to Ptilophora and Petasia, Steph., and not to the buflf tip-moth 

 (Pygsera buce])hala). Its food, according to Abbot, consists of the Andromeda mariana, 

 vulgarly called the male hackleberry, which grows round ponds and on the margins of 

 running streams ; it eats also several species of walnut and oak. One went into the ground 

 on the 31st of July, and the moth came out the SSrd of August ; another went in the 8th of 

 June, and came forth the 3rd of July. They likewise sometimes go into the ground in 

 autumn, and come out in the spring. The whole brood of caterpillars feed together in 

 society. Abbot also states, that when they eat walnut leaves they are always black, with 

 white hairs ;* when their food is the oak, they are more yellow.

• Neither in Abbot's figure, nor in my specimens of this larva, is there any appearance of hair upon the body, and it cannot be 

 supposed that a variation in the nature of the food could have the effect of clothing some specimens with hair whilst the rest 

 are naked.
