" Xenos, the genus serving as the type of this singular order of in- 

 sects, was discovered by Rossi, who referred it without hesitation to 

 the Ilyinenoptera, and placed it next to Ichneumon. Another ge- 

 nus of the same order was f(jund by Kirby, and was described in his 

 celebrated JMonoi^rapliia /(piiin Anglitc under the name of Slylops, 

 with expressions of doubt as to its systematic situation. Latreille 

 soon after received trom I)e iJrcbisson a species of .Stylops, and at 

 the end of his Genera Inaeelormn ct Cnistaccorum, observes, that it 

 seems to disturlt our entomological systems, not being referable to 

 any of the estalihshcd orders. Professor Peck detected a new spe- 

 cies of this group in America, and counnunicated it to Kirby, who 

 considered it to constitute with his St\'lops a peculiar order of in- 

 sects, on which he gave a dissertation to the Linnean Society of Lon- 

 don, whioli was published in the eleventh volume of their 2runsac~ 

 tionx. I adopted the characters that were laid down by this learned 

 entomologist, as well as the name Strepsipteru, by which it was de- 

 signated. Since then Latreille has convinced me that the supposed 

 elytra are but moveable processes attached to the anterior part of 

 tlie thorax ; whereas true elytra arise from the second segment of 

 the trunk, and always more or less cover the wings, which these 

 j>arts do not touch. Anxious to become acquainted with all the 

 characters of the order, I commenced an examination of the mouth, 

 and was soon convinced that the parts of it were far from being ob- 

 .solete ; but tearing to undertake the dissection, I submitted the spe- 

 cimen to tlie inspection of Savigny, from whose exact and almost 

 infallible hand and eye I felt confident of gaining the desired infor-
