THE BRITISH NATURALIST. 



[May 



mimetic species of CEdemerida belonging to the genus Pseudolycus, Guer., and the 

 corresponding Lycida, which were found with them ; also specimens of both sexes of 

 Lamprima nitilans, Er. 



Mr. N. M. Richardson exhibited a specimen of Zygtxna filipendulcB with five wings; 

 a second specimen of the same species with the middle legs on the right side much 

 dwarfed ; four specimens of Gelcchia ocellatella, including a pink variety, bred from 

 Beta maritima ; four specimens of Tinea subtilella, a species new to Britain, taken last 

 August in the Isle of Portland ; also specimens of Nepticnla auromarginella, a species 

 new to Britain, bred from larvae taken near Weymouth on bramble. Dr. Sharp and 

 Mr. M'Lachlan commented on the structural peculiarities of the two specimens 

 of Zygana. 



Mr. C. Fenn exhibited a series of Taniocampa instabilis, which had been bred out of 

 doors during the recent severe Vv'eather. They were all bred from ova laid by the 

 same female, and many of them were of an abnormally pale colour. Mr. Fenn said 

 that, according to Mr. Merrifield's theory, these pale specimens, in consequence of 

 the temperature to which they had been subjected in the pupal state, ought to have 

 been very dark. Mr. Jenner Weir, referring to the pale specimens, said he had never 

 before seen any of so light a colour. 



Mr. W. Dannatt exhibited a butterfly belonging to the genus Crenus, recently 

 received from the Lower Congo. He said he believed the species was undescribed. 



Mr. G. A. J. Rothney sent for exhibition several specimens of an ant (Sima nifo- 

 nigraj, from Bengal, together with specimens of a small sand wasp {Rhinopsis 

 nificovnis) and a spider (Salticus), both of which closely mimicked the ant. It was 

 stated that all the specimens exhibited had lately been received from Mr. R. C. 

 Wroughton, Conservator of Forests, Poona. Mr. Rothney also communicated a 

 short paper on the subject of these ants and the mimicking sand wasps and spiders, 

 entitled " Further notes on Indian Ants." 



Mr. G. C. Champion read a paper entitled " A list of the Heteromerous Coleoptera 

 collected by Mr. J. J. Walker, R.N., in the neighbourhood of Gibraltar, with des- 

 criptions of four new species." At the conclusion of the meeting a discussion ensued' 

 % which Mr. Kirby, Capt. Elwes, Mr. M'Lachlan, Mr. Jenner Weir, Dr. Sharp, and 

 Mr. Crowley took part. — H. Goss, Hon. Sec.

 Mr. Skinner, of Putney, was elected a member. 



Mr. C. Fenn exhibited a long series of Taniocampa instabilis, bred from ova ob- 

 tained from a female at Lee, Kent, and remarked that the forms were mostly of a 

 very pale grey or brownish tints, banded with dark grey and purple, and showed a 

 strong tendency towards the form of the female ; out of nearly 100 that were bred, 

 two-thirds followed the type ; the pupai had been expcjsed to the intense trost of the 

 winter, and the moths emerged within a fortnight after the frost breaking up, and in 

 his opinion the preponderence of the pale forms did not corroborate Mr. Merrifield's
