a small one on the upperside of the forewing in the submedian inter- 

 space ; sometimes there is a large narrow mark ; sometimes a large broad 

 mark as in Mr. Moore's group B. In some hundreds of specimens which 

 I have examined I have found every intergrade between these four forms, 

 which goes to prove that in some groups of Euploeas the " male-marks " 

 cannot be used in even a subgeneric sense. Dr. Hagen as late as 1S89 

 noted that E. distautii is everywhere very common around the feet of 

 the traveller. It may here be mentioned that all the brown Eupleeas: — 

 bremeri, moorei, distantii and segyptus (which follows) "were all more or 

 less plentiful in Deli so long as there were forests. But owing to the 

 cultivation of tobacco all the forests have been cut down, the brown 

 Euploeas have become rarer and rarer in the true tobacco districts? but 

 may still be found as plentifully as in former years only on the boun- 

 daries of Deli, Langkat andSerdang, where again the forests commence. 

 Even E. distantii is now decidedly rare in Deli and Langkat proper.

 Moore. The commonest species of Euploea both iu the plains and hills in 

 Sumatra. It is found all the year round and always in fresh generations. 

 Of all the species of Euploea it is the most mimicked, in the female by 

 the female of Eh/muias laisidis, de Niceville ; in the male by the third 

 form of the female of Euripns halitherses, Doubleday and Hewitson ; 

 in the male by the first form of the female of Hypolimnas anomala,
