a small one on the npperside of the fore wing 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 usecl in even a subgeneric sense. Dr. Hagen as late as 1889 
noted that E. distautii is everywhere very common around the feet of 
the traveller. It may here be mentioned that all the brown Euploeas :— 
bremeri , moorei, distautii 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 tobncco districts, but 
may still be found as plentifully as in former years only on the boun¬ 
daries of Deli, Langkat and Serdang, where again the forests commence. 
Even E. distautii is now decidedly rare in Deli aud Langkat proper.

Moore. The commonest species of Euploea both in 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 Elymnias laisidis , de Niceville ; in the male by the third 
form of the female of Euripus halitherses, Doubleday and Hewitson; 
in the male by the first form of the female of tlypolimnas anomala ,
