LITHOSIID.E. 179 



brown transverse lines, the two outer ones near together and 

 parallel with the hind margin, the other nearer the base, with a 

 sharp angle in its middle. On the costa is a small double 

 streak of the same colour. The hind-wings are brownish- 

 white. The head, antennae, and body arc white. It is a 

 somewhat rare species in England. 



Exotic Genera of Lithosiid(B. 



The LithosiidcE. are a very numerous Family, and I cannot 

 here attempt to do more than briefly notice a few of the more 

 interesting and important foreign genera. 



/osiodes, Felder, includes a number of Tropical American 

 species, which are very much alike, and share a style of colora- 

 tion which is frequently met with in various Families of Butter- 

 flies and Moths inhabiting the same countries. They gene- 

 rally measure rather less than i j^ inch across the fore-wings, 

 which are much longer than the hind-wings, with the costa 

 slightly curved, and the hind margin very obliquely rounded ; 

 the hind-wings are two-thirds as long as the fore-wings, but 

 not broader, and the hind margin is rounded. The colours 

 are black, with one or two tawny transverse bands or large 

 blotches on the fore-wings, and sometimes one on the hind- 

 wings also. 



Bizone, Walker, is a very pretty and rather extensive genus 

 of Moths, chiefly found in India and the adjacent countries, 

 though not unrepresented in Africa, Madagascar, the Moluccas, 

 &c. They generally measure from one to two inches in expanse: 

 The fore-wings are oval, and not much longer than the hind- 

 wings, which are almost equally broad. Most of the species 

 can be recognised at a glance, for they have white fore-wings, 

 with two transverse red lines in the middle, and tiie iiind margin 

 narrowly bordered with red; between the central lines is a con- 

 spicuous rouiid black dot (sometimes more), and sometimes
