ON THE LARVA OF D1PETHERA DERIDENS, GuSnie. 



BY W. SAUNDERS, LONDON, ONT. 



A single specimen of the larva of this insect was taken crawling on a fence 

 on the 1st of October, 1866. It must be very rare in this locality as I had 

 never seen it before, nor have I observed it since, nor ever captured a speci- 

 men of the imago, which is very handsome. Food plant unknown. 



Length 1-20 in. cylindrical.
