they may serve as signals between individuals, as the creatine 

 is apparently mute. Also a small Caloptenus italicus, L., <$, 

 together with a Sphingonotus caerulans, L... y. which were

Mr. Rowland-Brown inquired whether the Macedonian 

 insects of other orders than Lepidoptera were predominantly 

 Western. He had been struck by this characteristic of the 

 butterflies sent to him from Salonica. Capt. Burr replied 

 that this was so, and that the fauna of the northern Balkans 

 was much richer than that of Macedonia, especially in the 

 plains. He added that one rarely saw a bird either that one 

 might not as well have met with in England. 



Chalcid in undigested seed. — The President exhibited 

 a Chalcid, Torymus elegans, Borkh., sent to him by the Rev. 

 E. A. Woodruffe-Peacock. which had emerged from a hawthorn 

 seed which had passed through the alimentary canal of a 

 blackbird, together with the seed from which it had emerged. 

 He said that it had been parasitic on some insect, probably 

 a Cecidomyid, which had been feeding in the seed. 



Mr. Green asked whether there were not Chalcids that fed 

 directly upon seeds, and the President replied that this was 

 the case, but that this species was parasitic. 



Dr. Neave remarked that there were Chalcids that fed 

 within the stones of almonds and plums. 



Butterflies of the Genus Castnia and a mimetic 

 Hesperid. — Mr. L. B. Prout, on behalf of Mr. J. J. Jokey, 

 exhibited the following species : — 



Cast a ia erycina, Westw. (P.Z.S., 1881, p. 141, pi. xii, fig. 4), 

 paratypes out of the Druce collection, together with an 

 apparently very rare Erycinicl butterfly (genus Xenandria '.) 

 erroneously described by Druce as " Castnia " pelopia (E.M.M. 

 xxvi, p. 69). Druce was evidently misled by the marvellous 

 resemblance between these two, and did not examine the 

 structure. A careful discussion of these forms by Houlbert 

 (Oberth., " lilt. Lep." xv. pp. 651-8) is in part stultified by 

 the fact that Westwood's figure is unrecognisable, showing a 

 red band which is really wanting, in consequence of which 

 he has thought to have discovered a new species pehpioides, 

 which will really sink to erycina; in pari also by Druce's
