pointed out that the $ was almost an exact copy of Planema 

 pogyei, Dewitz ; also another new Mlmacraea which he proposed 

 to name costleyi, after its discoverer Mr. Costley-White at 

 Mlanji, Nyasaland, and which appeared to be allied to M. 

 marshalli, Trimen, a specimen of which Avas also shown for 

 comparison. 



Mr, S. A. Neave described the capture of these specimens. 

 This species in common with several others flies very high, 

 and he said that it was often necessary to employ small native 

 boys perched at the top of the trees and armed with nets. 



Several Fellows commented shortly on this exhibit. 



Butterflies from British Honduras and Guatemala. — 

 Mr. A. E. GiBBS exhibited a drawer of butterflies from these 

 localities, and made the following observations : — I recently 

 received from Dr. Davis, of Belize, a small collection of butter- 

 flies collected in British Honduras and the neighbouring 

 Republic of Guatemala, and I have brought up a few of the 

 most interesting of them, with regard to some of which I have 

 received valuable notes from the sender. 



Papilio philolaus, Bsdv. — There are four specimens of this 

 Fapilio which exhibit considerable differences, two of them 

 having the yellow transverse bands, common to both wings, 

 very much more pronounced than in the other two specimens, 

 which were altogether darker. It is well known that this 

 variation exists in this species, and Rothschild and Jordan, 

 in their " Revision of the American Papilios," suggest that 

 the dark and pale specimens belong to different broods, and 

 that it is a parallel case to the seasonal variations exhibited 

 by the allied Papilio marcelhis, Cr. (ajax auct.), of North 

 America. It is an interesting point, and I wrote to Dr. 

 Davis to see if he could clear the matter up, and he replied 

 that he hardly thought that the differences could be seasonal, 

 for, as far as he knew, the perfect insect only appears during 

 the dry months of the year, Feb.-April. He had never seen 

 a specimen when the rains became well established, i. e. at 

 the beginning of June. "In this colony," he says, "it is a 

 somewhat local species, but, where found, always in abund- 

 ance, the favourite locality being the drying sands of rivers, 

 close to the water's edge. Here they settle in myriads, each
