280 THE ZOOLOGIST. 



1 



Entomological Society of London. 



June 3, 1891.— Mr. Frederick DuCane Godman, M.A., F.R.S., 

 President, in the chair. 



Mr. J. M. Ayde, of Somerford Grange, Christchurch, Hants, and the 

 Rev. John Seymour St. John, B.A , of 42, Castlewood Road, Stamford 

 Hill, N., were elected Fellows ; and Mr. R. A. Dallas Beeching, was 

 admitted into the Society. 



Mr. E. B. Poulton exhibited living larvae of Endromis versicolors and 

 commented on their habits. 



Mr. W. F. H. Blandford called attention to the fact that the larvae of 

 Liparis monacha remained in small groups on the bark of the tree for 

 about a week after emerging from the eggs, and that this fact was taken 

 advantage of by the German foresters to destroy them. Also that he had 

 himself verified the statement that uric acid can be detected in the mal- 

 pighian tubes of insects. Mr. M'Lachlan agreed that the demonstration that 

 the malpighian tubes were of the nature of renal organs was now satisfactory. 



Mr. C. J. Gahan exhibited two species of Coleoptera that he considered 

 to possess a mimetic resemblance, viz. Estigmena chinensis, one of the 

 Hispidce, and a nondescript Lamiid allied to Pemptolasius. He called 

 attention to a peculiar structure of the antennae in the latter by which the 

 resemblance was increased. 



Mr. J. W. Tutt exhibited a hybrid between Amphidasis prodromaria and 

 A. betularia, obtained by Dr. Chapman. Mr. Stainton commented on the 

 fact that the two insects appeared at different times ; and Mr. Tutt stated 

 that the A. betularia had been subjected to forcing, so as to cause it to 

 emerge at the same time as A. prodromaria. 



Mr. Tutt also exhibited forms of Caradrina, some of which he said 

 were considered distinct on the Continent, though they were not recognised 

 as such in this country, viz. Caradrina taraxaci (blanda), C. superstes, Tr.,^ 

 from Sligo, and C. superstes, H.-S., considered as synonymous with' 

 superstes, Tr., but apparently more closely allied to C. ambigua. 



Mr. B. A. Bristowe exhibited varieties of Arctia menthastri, some of 

 which had been fed on mulberry and others on walnut; no difference was 

 observed in the variation. 



Mr. G. Elisha exhibited larvae in their cases of Coleophora vibicigerella 

 and C. maritimella. 



Mr. A. G. Butler communicated a paper entitled " Additional notes on 

 the synonymy of the genera of Nocluid Moths."— David Sharp, V.P., 

 Acting Secretary. }
