at Para, Verlumnus keeps itself perfectly distinct from, although existing in the 

 same forest with the lorni there represeniing P. I'mteus, viz. liie P. tlieioclei. 

 Gray. VeititimKtu is found in the hiunid forests near Para, j;enerally in company 

 with P. ^J^fieus, flying slowly : on the Upper Anjazon it delights to settle on the 

 moist margins ot the rivulets which there flow tlirougii every lavine in the lorest, 

 where in the cheiiuered shade many of the nPiOst beautiful forest butlei flits love to 

 congregate, as P. Ciamtis, Pieris Loieua, Euhugis Penh and many others. 



Local var. Cutora, Ciray, ioc. cit. 'J his foim has a veiy diU'erenl aspect from the 

 type, on account of the peculiar coloui of the spot of the fore wing, which is 

 yellowish-olivaceous instead of green. In tlie example before me tlie opalescent 

 crimson spots of the hind wing are only two in number, and, beneath, are yellow in 

 colour ; tlie fringe also is yellowish. Had it occurred in numbers in its locality, 

 to the exclusion of the type, I should have treated it as an independent or fixed 

 form of its group. It is found on the Upper Amazon only, at Kga and St. Paulo, 

 in company with the type but inucli raiei. I have an example of a J from P^ga, 

 which 1 consider to be ihe J of Cutora ; I add a diagnosis of it. P. Culova J . 

 Size and form of P. Diceros, dentations of the hind wing much less acute. Foie 

 wing immaculate above and beneath, and of a fuscous colour. Hind wing with a 

 sub-opalescent crimson belt, similar in form to that of P. Diceros, h\i\. wanting the 

 outermost spot : the belt beneath pale rose colour.

The $ is tolerably constant to the type as figured by Gray. It varies, as do 

 all the species of the group, in the greater or less piominence of the dentations of 

 the hind wing: the opalescent crimsoii macular belt of the hind wing vaiies in 

 breadth, and the number of spots of which it is composed varies from three to 

 five. In some individuals the belt is in the same position as it is in examples of 

 the P. ProU'Ui of Rio Janeiro. The J varies more than the ^, The white 

 spot of the fore wing varies in size, but it is always of a cWar white. The crimson 

 belt of the hind wing consists of five or six spots (the anal one sometimes gemi- 

 nated) rather widely separated ; sub-oval in shape, varying in size, the second and 

 third always the largest, the tifth often large and rounded: it crosses thewin;^ 

 in the same position as the macular bell of the $ . I'he range of the species is 

 restricted to Para. It will probably be found also in the other northern provinces 

 of Brazil, and must be looketl upon as the representative in these regions ot the P. 

 Proieus of Rio Janeiro. It flies in the same forest as its ally P. Vertumnus, but 

 pi-efers the dryer areas, where the soil is light and sandy, Vertumnus being lound 

 moie in the lower and muisler disliicts. They keep themselves perfectly distinct, 

 and no instance of hybridity has come under my notice. Ihe ioniisot this group 

 lesembling Proteus are numerous, and taken together have a wide range. At 

 Corrientes, on the Plata, beyond the tropics, a magnificent form occurs, P. Orhig- 

 j/i/u/i (IS, Lucas ; in Bolivia and in the forests of Peru, east of the Andes, P. Ertares, 

 Gray (Cat. B. iNI. pi. 8, f. 9). In Venezuela there is a beautiful representative, 

 viz. P. Eriihalion, iioisd. (Gray, 10*, f. 3 and 4) ; in New Granada, P. Serupn, 

 lioisd. (Sp. Gen. t. 1 B. f. 2), which comes nearer our P. Hierocles. In Hon- 

 duras there is P. Iphidumas, F. (Gray, pi. B, f. 1 and 2), and in Mexico, P. 

 Panares, Gray (pi. 10, f. 4), of which P. ALeclor, Bdv, MSS., is probably the $ . 

 Lastly, in the east, probably in the Island of I'rinidad, there occus P. Cynmchles, 

 Dd. (Gray, pi. 10, f. 6). No representative has as yet been found in Guiana,* or 



• Since writing the above I liave acquired a specimen of a Papilio from Deme- 

 rara, which resembles P. Tetmosis (Cram. 211 C), but also approaches rn many 

 points P. Hierocles of Para, and P. Erillmliou of Venezuela. 1 add a brief de-
