glossed area or patch — extending below the costal vein to the radial veinlet, from 

 the upper base of the cell to below the apex of the wing. A similar broad but less 

 unglossed patch is present in Andrapana (Columella, Cram.), or entirely unglossed in 

 Ard. Jumba. In Kalkasia ( Alwina), and several other genera — ISfeiitis (Aceris ; Varma, 

 etc.), Bimhisara (Sankara), Stabrobatef^ (Radha ; Viraja) this unglossed patch on the 

 hindwing is confined to the medial area below the costal vein. Stab. Viraja, in the 

 dry-season form, has also a conspicuous tuft of laxly-exserted lengthened clavate 

 black (? scent) scales on the underside of the abdomen, disposed laterally along its 

 middle segments. Tliis tuft was not observable in males of wet-season Viraja which we 

 have examined. In Paraneptis (Lucilla) the unglossed patch on the hindwing is 

 restricted to the basal interspaces between the costal vein and lower subcostal. In 

 Bimbisara Aiijana the glossy grey of the costal border extends medially to below the 

 first subcostal veinlet, and encloses an oval pale ochreous-yellow unglossed patch of 

 scales between base of costal vein and first subcostal. In Acca (Venilia, Linn.), in 

 addition to the short unglossed area on the hindwing, there is an elongated 

 fusiform patch of raised (? scent) scales extending along the anterioi'ly-dilated 

 edge of the middle of the costal vein. In Bahinda (Hordonia) and La>iipipa (Helio- 

 dore. Fab.) the glossy grey costal border extends to below the second subcostal in 

 the dry-season form, and isolates a conspicuous unglossed elongated (? scent) patch 

 of brown scales between the bases of subcostals ; this patch, in the wet-season form, 

 pervading the interspace below the second subcostal veinlet. In Bahinda aurelia, 

 the bi'oad costal area extending to below base of subcostals is very conspicuously 

 glossy satiny-white throughout its entire area. In ^{.i'fl^^i'a (Neriphus, Hewits.) an 

 isolated dull brown patch of scales, between the bases of the subcostals, is 

 conspicuously apparent on the medially disposed glossed area. 



Sexual Dimorphism, and Mimicry of species within the Group. — In most of the 

 genera of this group the sexes of the various species are similar in both colouring 

 and markings, but, in the Athymid genus Pantoporia, the sexes of all its species are 

 dissimilar, the males having white markings, the females being mostly differently 

 marked, and the markings of a different colour, and in this respect closely I'esembling 

 certain species of other genera within the group, as follows : — 



In Pantoporia Cama and P. Inara, the females have ochreous-red markings — ■ 

 mimicking probably the red-banded Neptid, Stabrobates Viraja and its allies, whereas, 

 in the closely allied Pant. Selenophora, the female is also entirely dissimilar from its 

 male, but has white markings on the upperside, disposed exactly as in both sexes of the 

 allied Athymid genus Condochales — being an excellent mimic of C. opalina, even to 

 the white band on the abdomen, this band not being present in the male of 

 P. Selenophora. In the allied Pantoporia Zeroca (the male of which on the upper- 

 side is extremely like the male of Pant. Selenophora), the female, on both the upper
