larva, pnpa 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. Xyleutes litnratits, Donov., a pair, 

 showing great disparity in size of the sexes, also a pupa of male 

 and one of female. 



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

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

 orni/thum, 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. orni/thiou which is apparently a rare insect. There 

 are two specimens in the Godman collection now at South Kensing- 

 ton, one from Mexico, and one from Guatemala ; also a drawing 

 of Boisduval's type specimen in the Bordeaux Museum. When 

 Eothschild and Jordan published their Rei-isinn of the American 

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

 It approaches rather closely the central American form of P. hjco- 

 pliron, known as pallaa, but it has several points of distinction, one 

 of which is the very much narrower yellow median bands, and 

 there is an additional row of spots in the black band on the 

 underside of the forewing which is well seen in my example. Below 

 it is a specimen of /'. iycophron var. pallas for comparison. 



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

 on the same journey. 



P. coluwbns, H.Sch. {iiitndlachianmt, 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 be- 

 lieve, to the eastern end of it. 



P. sesostris var. zestos, Gray. This is a fairly common species in 

 the northern half of Central America and may be distinguished 

 from more southern sub-species by the red patch on the inner 

 margin of the hindwing. 



P. lyciiiienes, two of which I show (<? and ? ), is another Papilio 

 which comes in numbers from Guatemala and other Central 

 American countries. 



P. torquatus, Cr., is a Brazilian insect. 



P. homerus, F. This fine species is, I believe, found only in
