After arranging the fine combined series of the Museum and 

 G-odman and Salvin collections, I have been forced to the con- 

 clusion that, at most, the genus Nychitona consists of two very 

 variable species — N. medusa (African) and N. xlpliia (Asiatic) : 

 but, even then, several of the forms of each species are barely, if 

 at all, distinguishable. In Kirby's Catalogue Cramer's incorrect 

 locality ' Coast of Bengal ' is adopted for N. medusa ; but the 

 insect figured is of a purely African variety and was probably 

 received from Sierra Leone.
