stated that he had taken Papilio merope and P. cenea, in coimld, and had 

 obtained eggs and young larvae therefrona. 



Mr. Roland Trimen observed that, to the best of his knowledge, Papilio 

 cenea, StoU, was a form of the female peculiar to the South, and that the 

 female intended by Mr. Rutherford was probably either Hippocoon, Fab. 

 (the prevalent West African form), or Trophonius, Westw., var., or possibly 

 the somewhat intermediate form named Dionysos by Doubleday, also in- 

 habiting Western Africa. In any case the observation was important as 

 confirming the statements as to the polymorphic condition of the female of 

 merope. 



Prof. Westwood exhibited a globular gall on the surface of a sallow-leaf, 

 made by a species of TenthredinidiB ; also a Dipterous larva [Syrphus), found 

 closely adhering to the stem of a pelargonium. 



Mr. W. F. Kirby exhibited, on behalf of the Rev. J. K. Brown, of 

 Maidstone, a remarkable variety of Epunda lutulenta ; and, on behalf of 

 Mr. Ralfe, a specimen of Apatura ilia, which this gentleman stated he had 

 captured in Pinner Wood last July. 



Sir John Lubbock exhibited some interesting larvae which Mr. Calvert 

 had forwarded to him from the Troad, through Sir J. Hooker. He stated 

 that these larvse had recently appeared there in great numbers, and were 

 likely to prove most useful, as they fed on the eggs of locusts. The larvae 

 were, in his opinion. Coleopterous, probably those of a beetle allied to 

 Cantharis. Mr. Riley had recently described the transformations of certain 

 insects belonging to this group, and natives of the United States. The 

 young larvae on first hatching are thin, active little creatures, which eat 

 their way into the cases of locust's eggs, where they rapidly grow into fat, 

 fleshy grubs. Mr. Calvert states that in his neighbourhood a large pro- 

 portion of the locusts' eggs have this year been destroyed by these larvae. 

 Sir John Lubbock suggested that if the species does not exist in Cyprus 

 it might be worth while to introduce it there. 



Mr. Roland Trimen exhibited the wingless female Hymenopteron, of 

 which he had recently sent a sketch and brief account to the Society (see 

 Proc. Ent. Soc, July 7th, 1880, p. xxiv), and which, from all the circum- 

 stances attending its discovery near Cape Town by Mr. C. A. Fairbridge, 

 he had strong grounds for regarding as the female of the well-known Dorylus 

 helvolus, Linn. He also showed a second specimen of the same female, 

 presented to the South-African Museum by M. C. L. Peringuey, which was 

 stated to have been found near Cape Town on the surface of the ground ; 

 whereas Mr. Fairbridge 's example had been taken at a depth of about 

 eighteen inches at the bottom of the nest of a small red ant, believed to 

 belong to the genus Anomma, of which Mr. Trimen exhibited three workers 

 found attached to the large female. The latter seemed clearly referable to 

 Gerstaecker's genus D ichthodia {Qtett. Entom. Zeit., xxiv., p. 76 ff, t. I.,
