Am {Wallace). cT?,B.M. 



Mimics several species of Drusilla. It is difficult to separate the 

 various forms figured by Mr. Hewitson, as it is obvious that the 

 female is subject to much variation. 



3. Dyctis melantho.

 Gagie Island {Wallace). 

 A local form of the preceding species. 



4. Dyctis esaca.

 (1851) ; Hewitson, Ex. Butt. iii. pi. Mel. 1. fig. 5 (1863). 



Assam (obtained 1848). Typed", B.M. 



This species is stated by Hewitson and Westwood to be East-Indian. 

 I find, however, that we obtained it through Mr. Warwick, from As- 

 sam. It probably mimics some form of Euploea allied to E. ledereri. 



5. Dyctis hewitsonii. 



Elymnias hewitsonii, Wallace, Trans. Eut. Soc. Loud. p. 327.
