NYMPHALID.E. DANAIN^. DANAI3. 35 



" One male and three females, the latter agreeing exactly with one another, from Great 

 Nicobar." No notice of its occurrence elsewhere has been recorded. The figure shews the 

 upper and underside of a female in the Indian Museum, Calcutta. 



Second Group. — Parantica. " Foie7vinq long, narrow ; inner margin lengthened ; first 

 subcostal nervule emitted at one-fourth before end of the cell and touching the costal nervure 

 near its end ; the second emitted immediately before the end of the cell ; cell long, narrow. 

 Hindwiug somewhat elongated ; exterior margin very convex ; abdominal margin short ; 

 costal nervure arched from base and thence extending along edge of the margin ; cell very long 

 and narrow. Male with two spatular-shaped scent-pouches, one (the largest) being on the 

 first median nervuie, the other (about one-fourth its size) on the submedian nervure, near their 

 end, each being visible on the underside by the slender swelling of these nervures at that part. 

 AntenncB with lengthened slender tip. Larva with two pair of fleshy filaments. Type, D. aglea, 

 Cramer." (Moore, ' Lep. Ceylon.' p. 7.) 



This group is further divisible into two sections, the first of which has for its type 

 D. cleona, Cramer ; the Butterflies of this section comprise the smallest species of the genus, and 

 are distinguished from all other species of Danais by having beautiful pure yellow tints on the 

 hyaline markings of the wings ; they are Malayan Butterflies, and within Indian limits are 

 extremely rare. Four species are included in the Indian list, but the claims of two of them 

 for inclusion rest on somewhat obscure data, especially those of D. aspasia, which is recorded 

 from south India. The Butterflies of the second section, type D. aglea, are rather larger in 

 size, and have no trace of the pure yellow tints ; their head-quarters too are in Malayana, but 

 they extend over the greater part of India, and some of the species are common where they 

 occur. Of the five Indian species, one is found in Ceylon only ; another, which is doubtfully 

 distinct from the Ceylon species, occurs throughout peninsular India ; another in north India 

 extending into Burma ; another in Burma extending to the Nicobars ; and the last is confined to 

 the Andaman Islands. They are all comparatively delicately-formed Butterflies, with rather 

 elongate wings, and having the hyaline markings usually preponderating over the blackish 

 ground-colour. 



Zey to the Indian species of Farantica. 



A. b. Males with two scent-pouches on the hindwing, visible on the underside by dilatation of the first 

 fKedian nei-^'ule and submedian nervure. Wings blackish, with hyaline markings. 

 a'. Of small size ; some of the hyaline markings tinged with pure yellow. 

 a'. With yellowish tints on both wings. 



a'. With only one, or two, very small discal spots between the third and 

 second median nervules. 



11. D. {Parantica) cleona, N. India (?), Java. 



h^. With two spots, the inner one filling the base of the interspace. 



a*. Outer margin of forewing convex and scarcely emarginate ; 

 the streaks between the discoidal nervules short and broad. 



12. D. (Parantica) PHILOMELA, Nepal (?), Java. 



b*. Outer margin of forewing highly emarginate ; the streaks 

 between the discoidal nervules long and narrow. 



13. D. [Parantica) CROCEA, Burma, Java, 

 i'. With yellowish tints on hindwing only. 



14. D. (Parantica) aspasia, Tranquebar (?). 

 ^'. Of rather larger size ; no pure yellow tints.

 very fine and white spaces wide. 



15. D. (Parantica) melanoleuca, Andamans. 

 b^. Fuscous, with dull hyaline bluish-white markings. 



a^. Forewing with the hyaline streak between the discoidal nervules almost 

 touching the disco-ceilular nervule. 



16. D. (Parantica) aglea, N. India, Burma, 



b". Forewing with the streak between the discoidal nervules not nearly reach- 

 ing the disco-cellular nervule. 



a*. Forewing lengthened and emarginate on outer margin, 

 hyaline markings large, prominent. 



17. D. (Parantica) cevlanica, Ceylon. 



18. D. (Parantica) grammica, S. India.
