Brazil (Trail). One specimen. 



From the mutilated condition of the specimen (the last two joints

 invisible, but I think I can see the bases of three.

 have been published in "Psyche," July, 1879, and the " Scientific

" 1st— Certain features belonging to the larva, and cast off with 

 its skin : 2nd — those belonging to the chrysalis ; and to intelligibly 

 explain the process, it is necessary to more fully characterize and 

 homologize these parts than has hitherto been done. 



" In the former category, in addition to the natural adhesiveness 

 of the moist, mucous, and membranous corium, there are three physi-
