mimicry. — Pi'ofessor E. B. Poulton, F.R.S., exhibited the male and 

 female imago, the presei'ved larva, and the cocoon of an interesting 

 new Lasiocampid discovered by Mr. E. L. Clark near Durban ; a set 

 of butterflies captured on a patch of zinnias on February 21st, 1906, 

 at Jinga, on the north of the Victoria Nyanza, by Mr. C. A. Wiggins, 

 showing seventeen specimens of Danais chrysippus, L., of the type, 

 and alcipinis forms together with the intermediate examples, but no 

 single specimen of dorippus (kliujii), although of three females of 

 Hypolimnas misiiJims, L., two were of the inaria, Cr., form mimicking 

 dorippus. — Professor Poulton also read a letter from Mr. S. A. Neave, 

 describing the habits of a mimetic species of Euphadra. — Dr. F. A. 

 Dixey exhibited specimens of Heliconius amphitrite, Eiff., and H. 

 charithonia, Linn. ; also a coloured drawing of H. hermathena, Hew. 

 He remarked that each of the first tw^o species showed a distinct and 

 well-marked aposeme or warning character ; each of them, and 

 especially the first, belonging to an extensive mimetic assemblage. 

 In the third species these two distinct aposemes were combined. The 

 specimens showed how a conspicuous and distasteful form might 

 acquire a new aposeme without relinquishing its old one, such an 

 intermediate form presumably sharing in the protection afforded by 

 the aposematic forms on each side of it, while the separate aposemes 

 which it exhibited were not mutually protective. — Dr. G. G. Hodgson 

 exhibited a series of Polyomviatus bellargus from Surrey localities, 

 including a partially gynandromorphous female, two-thirds of the 

 hind wings with the typical male coloration and markings ; a series 

 of var. ceronus taken in 1907, and specimens showing a variant under 

 side recurrent in the same locality. He also exhibited a series of 

 Zygana trifolii and Z. liippocrepidis from one locality, including 

 twelve melanic examples of the former, with other common forms 

 and aberrations, probably of the latter, the sixth spot being obsolete, 

 or represented by a mere dot. — Mr. J. C. Kershaw communicated a 

 paper on " The Life History of Erianthus versicolor," Brunner, an 

 orthopteron of the family Mastacidae.— H. Rowland-Brown, M.A., 

 Hon. Secretary. 



The South London Entomological and Natural History 

 Society.— Octo&er ^2nd, 1908.— Mr. Alfred Sich, F.E.S., President, 

 in the chair. — Mr. McArthur exhibited a long series of Argynnis 

 aglaia and fine specimens of Asteroscopus nubeculosa, from Aviemore. 

 — Mr. Tonge, bred specimens of Pieris hrassicce with partial black 

 margin to hind wings, Cerura bifida bred from a Eeigate female, a 

 very varied series of Agrotis cursoria from Low^estoft, and a long 

 series of Hydroecia nictitans from the same place. — Messrs. Harrison 

 and Main, a bred series of Nemeobius lucina from ova, Horsley ; and 

 tiro larvae of Limenitis sibylla in their curious hybernacula, on 

 sallow, from the New Forest. — Mr. Hodgson, a large number of Pieris 

 rapce, illustrative of the experiments he was making on the species. — 

 Mr. R. Adkin, series of Bhodophcea suavella and B. marmorea, with 

 branches of blackthorn showing their larval w^ebs, from Eastbourne, 

 and read notes on the species ; a specimen of Peronea permutana 

 bred from a larva taken on Bosa spinosissima at Beachy Head ; and 

 unusually light and dark forms of Tortrix heparana from tlie same
