 and Macaridse, among which are a great number 

 of the " Wave " and other Moths, and to pro-

 female are simple, as seen in the illustration.

 has finished feeding, it envelopes itself in a silken 

 hammock fastened to the stems of the plant on 

 which it fed. The Moth flies at the end of the 

 summer and beginning of autumn.

 grey, peppered with tiny dark dots and crossed 

 diagonally with light brown stripes, three on
