since detected. I hope, however, by the dissections with which I 

 shall always illustrate the subjects, that I may be able to interest 

 entomologists sufficiently to induce them to attend to the structure 

 of this beautiful Order. 



A doubt was expressed by Haworth whether the following insects 

 might not be merely varieties ; but the numerous specimens which 

 have since then been collected, do not strengthen such a conjecture, 

 and the addition of the novelty figured renders it still more probable 

 that they are distinct. Mons. Duponchel, however, does not seem 

 to doubt their being varieties, but until they are reared from one 

 brood of caterpillars I must be allowed to retain my opinion.

 greyish, 2 faint strigae across the middle, the space between more or less castane-

The most abundant species, and occurs from July to December in

 on Salix caprea in July ; it lives between the leaves, which it unites in 

 a bundle at the extremity of the branches; it is green and hairy ; an 

 outline from Hiibner is added to our plate as well as the cocoon, 

 which is attached to a branch clothed with Lichen punastri^ Plum-
