called attention to the unusual abundance of Plusia gamma on the last few evenings. 

 Mr. Dobson, Mr. J. A. Cooper, Mr. Frohawk, Mr. Adye, Mr. Winkley, Mr. Tutt, 

 and Mr. Barrett also made some observations thereon. Mr. Jenner Weir delivered | 

 a Zoological lecture, in which he drew attention to some remarkable cases in which ! 

 mammalia and birds having been in remote geological times differentiated for one \ 

 mode of life had adopted entirely different habits.— H. W. Barker, Hon. Sec. ; 



Entomological Society of London : June 1st, 1892.— Kobert McLachlan, , 

 Esq., E.R.S., Treasurer, in the Chair. | 



The Hon. Walter Rothschild sent for exhibition Neptis mimetica, n. sp., from ! 

 Timor, mimicking Andasena Orope, one of the EuploeidcB, and Cynthia equicolor, n.sp., 

 a species remarkable for the similarity of the two sexes, from the same locality ; 

 also a hybrid between Saturnia carpini and S. pyri, and specimens of Callimorpha i 

 dominula, var. Romanovii, var. italica, and var. donna, bred by a collector at Zurich ; ] 

 he further exhibited a very large and interesting collection of R/iopalocera made by \ 

 Mr. W. Doherty in Timor, Pura, Sumba, and other islands, during October and ■ 

 November, 1891. Col. Swinhoe remarked that the various species of Neptis were 

 usually protected, and were imitated by other insects, and did not themselves mimic 

 anything, and that the pattern of the Neptis in question was very common among 

 the butterflies in the Timor group. Mr. Jenner Weir, Prof. Meldola, Mr. Trimen, 

 and others continued the discussion. i 



Mons. A. Wailly exhibited about fifty species of Australian Lepidoptera, mostly \ 

 from Queensland, and fertile ova of Trilocha varians, which are arranged in small ] 

 square cells, fastened together in large numbers, and present an appearance quite 1 

 different from the usual type of Lepidopterous ova. j 



Mr. F. Merrifield exhibited a series of Drepana falcataria, half of which had j 

 been exposed for a week or two, in March or April, to a temperature of about 77°, ■ 

 and the other half had been allowed to emerge at the natural outdoor temperature. : 

 The latter insects were in all cases darker than the former, all being equally healthy, i 

 Mr. McLachlan, Mr. Barrett, Mr. Jenner Weir, and others took part in the dis- \ 

 oussion which followed. 



Mr. C. Gr. Barrett exhibited a curious variety of the male of Arctia mendica, 

 bred by the E-ev. W. F. Johnson, of Armagh. 



Canon Fowler exhibited the egg case of a species of Mantidce from Lake Nyassa, 

 and specimens of Bledius dissimilis, Er., from Bridlington Quay, Yorkshire. i 



Mr. McLachlan called attention to the re-appearance in large numbers of the : 

 diamond-back moth, Plutella criiciferarum, which was very abundant in gardens j 

 near London, and expressed his opinion that the moths had been bred in the country i 

 and had not immigrated. | 



Mr. Jenner Weir, Mr. Bower, and Prof. Meldola stated that they had recently 

 seen specimens of Colias Edusa in different localities near London. j 



Mr. Jenner Weir and others also commented on the large immigration of Plusia j 

 gamma, and also on the appearance of a large number of Cynthia cardui and other j 

 Vanessidce. 



The Hon. Walter Rothschild communicated a paper on two new species of 

 Pseudacrcea.—W . W. Fowler, Son. Sec.
