After arranging the tine combined series of the Museum and 

 (lodman and Salvin collections, I have 1 been forced to the con- 

 clusion that, at most, the genus Nycldtona consists ot two \cry 

 variable species -JV. medusa (African) and X. tfiplim (Asiatic): 

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

 at all, distinguishable. In Kirby's Catalomie Cramer's incorrecl 

 locality 'Coast of Bengal' is adopted for A. nu-dnsn \ 1ml the 

 insect ligured is of a purely African variety and was probably 

 received from Sierra Leone.
