Compare Geoffe. St.-Hilaiee Ann. du Mus. xx. 1813, pp, 251 — 260; 

 Temminck Monogr. 11. pp. i — 39.— This genus is altogether peculiar to 

 the Eastern hemisphere and does not extend far towards the North, most 

 of the species being found in warm countries. The females of the European 

 species and also of most (though not all) of the exotic have at the posterior 

 part of the abdomen, close to the region of the pubic bones, two short, 

 flat, nipple-shaped appendages, of which the use is unknown. By day 

 these animals hang clinging by theii" hind feet with the body rolled in the 

 wings as in a mantle.
