 of two specimens, differing somewhat ia size. 



ScoPELoprs iNOPs, Stephens (Phytometra scopulaepes, Haworth), is omitted, as being a probable native of 

 Georgia, in North America. It is remarkable on account of its hind legs producing brush-like fascicles of long

 stigmatiferous ; they are weak, and comparatively of large size to the body, which is slender and linear ; the 

 palpi nearly horizontal, with the terminal joint very small ; the antennte slender and setaceous ; the thorax not
