This Adolias may be at once distinguished from its allies 

 by the violet inner half of the external ai'ea of the hind- 

 wings ; in A. Bnmnda it is bright l)lue, and in A. Salia 

 green : the close resemblance which the female bears to 

 Tanaecia Pvlautra i.^ very striking; indeed, before I dis- 

 covered the structural differences T)etween AdolidH and 

 Tanaecia, the two iusects were united as one sjiecies in our 

 Collection.
