Njmplialid butterflies of the genus Euthalia, of wliicli lepidea, Andersonii, Diardli, 

 Ambalika, etc., are representatives. 



Key to the Indian genera of Elyiiniin^. 



1. Forewing rather short, subtriangular. 



Section A. Forewing of male possessing a glandular patch situated between the base 

 of median and submedian vein. Hindteing with a very slight 

 caudate- angle to exterior margin. 



Section B. Forewing of male not possessing the glandular patch. Hindwing 



caudate Elymnias. 



2. Forewing elongated, triangular. Hindwing somewhat more or less caudate . . Melynias. 



3. Forewing elongated, subtriangular, exterior margins very slightly sinuous. Hindwing 



not caudate Bruasa. 



4. Wings short, very broad, exterior margins uniformly scalloped. Forewing of male 



with a longitudinal fold on poderior margin covering a glandular 



patcJi and 071 erectile tuft of hairs. Hindwing convex . . . Mijiadelias. 



5. "Wings very short and broad, exterior margms extremely-slightly sinuous . . . Agrosia.

Imago. — Male. Wings moderately broad. jPo?*erf;i?i(7 subtriangular ; costa very 

 convex, apex acute, exterior margin very slightly oblique and sinuous, posterior 

 margin slightly convex towards the base ; costal vein much swollen at the base and 

 terminating near middle of the costa ; subcostal arched near its base, the first and 

 second branches emitted before end of the cell ; the cell short and very broad ; 

 discocellulars inwardly oblique, upper angled close to the subcostal, lower radial 

 from slio-ht ano;le above the middle ; the two upper median branches emitted from 

 end of the cell, the upper median much arched ; submedian bent close to the median 

 at the base, thence slightly recurving to the posterior angle. On the upperside 

 between the basal interspace of the lower median and the submedian is an incon- 

 spicuous rounded hlach glandular patch, which, as seen under the microscope, is 

 clothed with laxly-raised short black scales,* with many-toothed tips, and by longer 



* AVe possess three specimens, from different localities, in which these scales nave been removed from 

 the patch on both wings daring the life of the insect, thus leaving the entire patch quite bare.
