Descriptions of Nymphs. 



All the nymphs described are raonodactyle. 



The descriptions all refer to the appearance of the full-grown 

 nymph. 



All the nymphs have the abdomen more or less soft. 



The full-grown nymph is always a little smaller than the adult, 

 except in the inert stage, when it is sometimes a trifle larger. 



Unless stated to the contrary the larva resembles the nymph, 

 except in its smaller size, and in having only six legs instead of 

 eight.

I found a few specimens at Epping Forest, and bred it from 

 the singular nymph, as to which 1 can confirm the correctness of 

 Nicolet's plate and description, except that I think the former 

 rather too red.

Nic. 432. 



I found a few specimens of this creature at Epping Forest. 

 The stigmatic hairs are a little longer and more pointed, and the 

 interstigmatic are further apart than in Nicolet's drawings.
