THE SOUTH LONDON NATURAL HISTORY SOCIETY EXHIBITION. 263 



XantJwrho'c sociata, banded specimen, Isle of Wioht, 1895. 



Mr. G. Talbot exhibited on behalf of Mr. J. J. Joicey, two drawers 

 containing rare Exotic Lepidoptera : — 



Ornithoptera alexandrae, Roths., a pair, and also a pupa case. O. 

 rnthschildi, Kenr., a male. Papilio ireiskei, Roths., a male from New 

 Guinea, and its ally P. macleayanns, Leach, from Queensland. A 

 similar species has just been discovered on Ceram, and described by Mr. 

 Rothschild as P. strescmanni. P. nuuskei probably represents a later 

 development of the older green form. A(/rias phalcidon, Hew., from 

 the Amazon. A(irias ami/don, Hew., from Colombia. Callithea 

 sappldra, Hiibn., a pair from the Amazon. Perimma ewinens, Ob., a 

 very rare species of this genus from Peru. 



Hepialidae from Australia. — Clnirania rainsayi, Scott, a pair, in- 

 cluding a Tineid moth which feeds on the larva of rcDiisai/i. Charagia 

 cijanochlura. Low., a pair. Chanv/ia inirabilis, Roths., a pair. C. 

 lewinii, Wlk., a small species of the genus, a pair. Xijlotypia staci/i, 

 Scott, the largest Hepialid, a pair; the ? measures over 9 inches 

 across the wings. 



Cossidae from Australia. — Xylextes ajfinix, Roths., a pair, also larva, 

 pupa case and the lid which covers hole in tree from which the imago 

 emerges. This lid is cut round by sharp processes found beneath the 

 shoulder flaps of the insect, and when free it is pushed off upon 

 emergence of insect. Xyleuten Uturatns, Donov., a pair, showing great 

 disparity in size of the sexes, also a pupa of S and one of ? . 



Mr. A. E. Gibbs exhibited some new world Papilionidwi recently 

 obtained by him and made the following remarks on them: — P. 

 orni/t/tion, Boisd. Twelve months ago my friend Dr. Davis and I 

 sent our collector to Guatemala. He spent most of his time in a 

 coffee plantation on the Pacific slope, but on his way home he 

 stopped at a place called Gualan on the Atlantic side about half- 

 way between the capital and the coast. From Gualan he sent me a 

 specimen of P. onu/tkion which is apparently a rare insect. There are 

 two specimens in the Godman collection now at South Kensington, 

 one from Mexico, and one from Guatemala and also a drawing of 

 Boisduval's type specimen in the Bordeaux Museum. When Roths- 

 child and Jordan published their Pierision of tite American Papilios 

 in 1906, there were also two Mexican specimens at Tring. It 

 approaches rather closely the central American form of P. bjcovhron, 

 known as pallets, but it has several points of distinction, one of which 

 is the very much narrower yellow median bands, and there is also an 

 additional row of spots in tlie black band on the underside of the fore- 

 wing which is well seen in my example. Below it is a specimen of P. 

 ii/cophrou var. pallas for comparison. 



P. niojiteznina, Westw. This specimen was also taken at Gualan 

 on the same journey. 



P. eolidiibiis, H.Sch. {(jinidlachianuft, Feld.). This is one of the 

 most beautiful of the new world Papilios, the brilliant blue band on 

 the forewing and the red distal area on the hindwing adding greatly 

 to its attractions. It is confined to the island of Cuba, and, I believe, 

 to the eastern end of it. Following the order of priority we must use 

 Herrich-Schaffer's name of coluwbus, bestowed upon it in 1802, rather 

 than Felder's more generally used name of (inndlacJiianus (which he 

 gave it two years' later, notwithstanding the fact that Kollar gave the
