Four examples. 



We previously only possessed two s])ecimens of this species, 

 which, owing to their general similarity to C. damasijjpe^ I 

 was unwilling to describe. There can now be no doubt that 

 the species does not vary. 



Family Lycsenidae. 

 Genus Danis, Fabricius. 



16. X'f/???'.? close to D. davn's ', perhaps a variety. In j)oor 

 condition.
