 W. H. ruGWELL, Esq., Ph.C, Pr sident, in the Chair. 



Mr, W. H. Tugwell exhibited a series of Bryophila perla, 

 W.V., showing great variation — all Kent examples. Those 

 selected from Deal showing orange coloration ; others collected 

 by Mr. Austen, at Folkestone, being all very dark ; the usual 

 white ground colour of the wings being replaced by a dark 

 greenish grey shade, giving the specimen a peculiarly dark 

 appearance. 



Mr. Tugwell also exhibited on behalf of Mr. J. E. Robson 

 of Hartlepool, a series of Lyccsna astrarche, Bgst. {agestzs, 

 Hb.), collected this season in Durham, and showing the 

 species in all its forms from one district, from the southern 

 form of agestis to the intermediate generally known Durham 

 form salinacis, St., and then to the artaxerxes. Fab., form. 

 He remarked that at one time these were looked upon as 

 three distinct species, but were now known as one. In one 

 of the specimens the usual white rings round the black spots 

 or the ocelli were entirely wanting. 



Mr. Turner exhibited a bred series of Hypsipetes sordidata, 

 Fb. [elutatd), fed on a mixed diet of hazel, whitethorn and 

 willow ; showing the red, pale, dark, and banded forms ; also 

 a living larva of Stauropus fagi, L. 



Mr. S. Edwards exhibited examples of the genus Charaxes ; 

 and read the following note : — 



"The genus Charaxes from its wide distribution forms one 

 of the most interesting genera of the Nymphalinse. One 

 species is found in Europe, on the Mediterranean shores ; it 

 also inhabits eastern, western, and southern Africa ; Mada- 

 gascar has some species, and the genus is common in 

 Continental India, Ceylon, and the Andaman Islands, through 

 Burma and the Malay Archipelago; very limited in the Pacific 

 Islands, but occurs in Australia, and in single species in 

 Fiji and New Caledonia. About fifty out of eighty known 

 species occur in the Ethiopian region, eight being peculiar to 

 Madagascar, and fifteen to South Africa, out of which the coast 

 of Natal produces ten. They are the fastest flyers of the 

 Nymphalinae. The larvse are finely granulated, thickened about 

 the middle, attenuated towards the tail, spineless, head large, 

 wide, flattened, crowned with four spinose horns, anal segment 

 more or less bifid. Pupa very thick, rounded, smooth ; back 

 convex ; head bluntly bifid ; anal segment with two small 

 tubercles inferiorly, and four others at its extremity, round 

 base of pedicel ; back of thora,x globosely prominent. The
