DAN MS. 



First Group. — Radf.na. " Fore wing moderately long, triangular ; first subcostal nervule 

 emitted at al)OUt one-third before end of the cell, and anastomosed to the costal in the middle ; 

 second nervule emitted before end of the cell. Hindwing broad, somewhat triangular ; costal 

 mar"in long, nearly straight ; abdominal margin long ; costal nervure very convex from the 

 base, and then extending straight along the edge of the margin; cell broad, long; subcostal 

 and median nervules very wide apart. No scent-pouch in the male. ^«/e;/«(Z- longer than in 

 allied genera, and with a more gradually thickened and blunt club. Larva {R. jtiventa) 

 with two pairs of fleshy filaments. Type, R. similis, Linnceus, from China." (Moore, Lep. 

 Ceylon, p. 3, 1880). 



Only three species of this group occur vsrithin Indian limits ; another occurs in Siam 

 (Z>./-?m»«7/V), and another in Java (Z?.y?/w«/a), and it is possible that these may one and 

 all be merely fixed geographical varieties of the type D. similis. The absence of the sexual 

 spot in the male is a very distinctive feature found in no other group of Indian Danais, and 

 linking this group with the foregoing genera. In the absence of the sexual spot the males 

 can be distinguished by the pointed tip of the tarsus of the imperfect foreleg, which in the 

 females terminates in a brush ; and by the narrower and less rounded wings. 



Ze^to the Indian species of Badena. 



A. a. Males with no scent-pouch on the hindwing ; both wings blackish, with subhyaline markings, 

 a'. The white streaks from the base narrow ; no defined black border to the wings. 



8. D. (Radctia) vulgaris, Burma. 



b^. The whitish spaces on the basal area greatly predominating, leaving a well-defined dark border 

 beyond. 

 a^- The cell in the hindwing with two broad black streaks. 



9. D. (Radena) exprompta, Ceylon. 

 I D. (^a</f«a) PERSIMILIS, Siam.
