110 On Rhopalocera from Brazil. 



on R. Tocantin?, between Porto Redl and Pard. Westwood 

 described this as a " Cethosia [Carolina^) red buff with 

 brown bars and white spots on margin of h. w." lie placed 

 it, as A. 15, among the Acrajina?. 



Metamorpha dido^ Linn. 



12. 3. 2^. = 1261. Rio de Janeiro. " Aqueduct." 

 17. 3. 26. = 1262. Rio de Janeiro. Along the Carioca 

 Aqueduct. (See 917.) ^'■Papilio'. The green species 

 frequents tiie tops of trees are [and] flies generally high 

 above reach." [This evidently refers to this species, 

 though the specimen bearing the date 17. 3. 26 does 

 not bear the no. 103T. Tiie latter, however, is borne 

 by a specimen of Vapilio aga'vus, Drury.] Westwood'a 

 list gives one specimen bearing 1057 and two with 

 17. 3. 26. The former and one of the latter are now 

 missing. 

 Bz. 20. 3. 26. = 1263. Rio de Janeiro. " Along the Cari- 

 oca Aqueduct." 



1. 1. 26. = 1264. Rio de Janeiro. " In the valley of 



Catumbi.^' 

 This specimen bears Westwood's number A. 19. 

 Bz. + 1316. 17. 2. 29. = 1265. Porto Real. " Feeding on 

 the flowers of the Waltkeria bushes (v. H. 66<3i?X )•" 

 (See 663.) 

 1316. 17. 2. 29. = 1266. As above. 



Westwood made two lists of this species, in one of which 

 he mentions only one specimen on this date, while four are 

 recorded on the other. 



2. 3. 29. = 1267. Porto Redl. 



7.3.29. =1268. Porto Redl. "The green papilio loses 

 much of the beauty of its green color within a day 

 or two after being caught." It is certain that the 

 "green papilio" is Metamorpha dido^ Linn., as Burchell 

 gives the above note on a specimen dated 6. 3. 29. 

 The specimen is now lost, but is mentioned by West- 

 wood in his list of this species. See also 1262^ 

 where this Papilio is described as "the green species." 

 The green pigment is not contained in scales, but exists 

 between the two membranes of the wing, being almost 

 certainly the blood or hasmolymph in a solid state, and 

 the colour due to mefachlorophyJl or some other modified 

 plant-pigment. Green markiugs caused in this manner 

 are also found in Victorina stelenes and several true 

 Papilioninse of the sarpedon group, also in the Pierine
