ECNOMIDEA PITHECIUM. 185 



head, and a rather larger pair over the tail. The 

 individual figured by Madame Merian (Surin. Ins. 

 pi. 28) has the lateral appendages rounded at the 

 extremity, and the body is mottled. She affirms that 

 it is venomous, and that the parts of the body which 

 it touches become stiff and inflamed ; a statement 

 which the history already given of the larva of Dora- 

 ticampa tends directly to confirm. The caterpillar of 

 E. Hipparchia (according to Stoll) is of a uniform 

 light brown colour ; when it changes to a chrysalis 

 the lateral flaps are folded round it. The moth is 

 reddish-brown, the upper wings variegated with a 

 lighter colour, each having a round white spot be- 

 yond the middle and a narrow curved band of the 

 same colour not far from the anterior margin. 



The moth here figured, E. Pitkecium, has the 

 upper wings bluish, with transverse waved bands of 

 yellowish-brown, and more or less clouded with 

 dusky : hinder wings entirely brown, with a narrow 

 yellow line within the fringe ; body of the female 

 rather thick, thorax and abdomen bluish, the former 

 brown on the side, and the latter with brown rings. 

 The body of the male is wholly light brown with 

 clouds of a deeper colour, the abdomen tufted at the 

 apex. The female expands an inch and three lines, 

 the male somewhat less. 



The caterpillar (Plate XXI. fig. 3) is wholly 

 brown, the head alone being yellow. It feeds on 

 persimmon and the various kinds of oaks. Abbot 

 states that it is found both in Georgia and Virginia, 

 but it is very rare. His specimen spun on the 10th
