THE BRITISH NATURALIST. 



[July 



identical, and of which Acuta, Walker is another synonym. He 

 states it is a species with a very wide range and that specimens are in 

 the British Museum from many parts of Asia, from Africa, and from 

 Australia. A Specimen of this insect, recorded as Acuta, Walker, 

 (" E.M.M.," vii, p. 8,) was taken at Tunbridge Wells, in June, 1870. 

 It was then stated that a single specimen from Congo, Africa, repre- 

 sented the species in the British Museum. We find Bimaculata, 

 Stephens, in the list of Canadian Lepidoptera, so that it would 

 appear to occur in North America also. It seems to be one of those 

 species which has been blessed with several names, and recorded 

 under each, to the mystification of all concerned. 



Report of Society. 



ENTOMOLOGICAL SOCIETY OF LONDON. 



'June 3rd, 1891. — Mr. Frederick Du Cane 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 versicolova, and commented 

 on their habits. 



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

 monaclia 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 malpighian tubes of insects. Mr. M'Lachlan agreed that 

 the demonstration that the malpighian tubes were oi 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 Hispido', and a nondescript 

 Lamiid allied to Pemptolasius. He called attention to a peculiar structure of the 

 antennse in the latter by which the resemblance was increased. 



Mr. 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. snperstes, Tr., from Sligo, and C. superstcs, H.-S., 

 considered as synonymous with snperstes, Tr., but apparently more closely allied to 

 C. ambigua. 



Mr. Bristowe exhibited varieties of Arctia mentJiastri, 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 syn- 

 onymy of the genera of Noctuid Moths." — David Sharp, V.P., Acting Secretaary.
