Upper Side. The antennae are pectinated. The head, thorax, and abdomen are white, striped 

 and spotted with black. The superior and inferior wings are also white, striped and freckled with 

 black. 



The under side is similar to the upper ; the legs and antennae are spotted. 



The caterpillars feed on oak, elm, &c. : they differ from each other in colour, as well as in 

 exterior form ; some being of an hazel, others very dark brown ; some have protuberances on the 

 various parts of the body, others have none. They are full fed about the beginning of September, 

 as at (b) ; when they go into the ground, and change into a black shining chrysalis, shewn at (c), 

 having a sharp pointed tail ; and about the end of May the moths appear. The female is shewn 

 Hying at (e), and the male at (/). 



Expansion of the wings two inches and a half.

Upper Side. The antennae are like threads. The thorax is crested. The abdomen is fur- 

 nished with tufts of hair, one on each annulus. The body and superior wings are of a dirty grey : 

 the latter having double lines, and undulated bars crossing them in several places, and a remark- 

 able spot on the bar tendon, in the middle of the wing, formed like a human ear ; the mark is seen 

 in many other species. The inferior wings are of a fine scarlet, having two broad bands or bars of 

 black. The upper side is seen at (T), the under side at (/), which differs from the upper side. The 

 body and legs are of a buff colour. The superior wings are of a dirty buff, having three dark 

 clouds crossing each. The inferior wings are red, having two dark bands. This moth has a spiral 

 tongue, and all the wings are dentated. 



The caterpillar seen at (#), feeds on willow ; is about two inches and a half in length ; in 

 colour so like the bark, that it is very difficult to see it. It becomes full fed about the beginning 

 of July, when it changes into chrysalis under the bark, within a spinning. The chrysalis is red, 

 covered with a fine bloom, as shewn at (z). The moths appear in August, and fly in the day. 



Expansion of the wings three inches. 



This is the most abundant of all the British species of Catocalse ; its large size 

 and varied colours rendering it very conspicuous.
