June 1, 1892. — R. McLachlan, Esq., F.R.S., Treasurer, in the chair. 



The Hon. Walter Rothschild sent for exhibition Neptis mimetica, n.s., 

 from Timor, mimicking Andasena orope, one of the Euplceidae, and Cynthia 

 equicolor, n. s., 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 dominula, var. romanovii, var. italica, 

 and var. donna, bred by a collector at Zurich ; he further exhibited a very 

 large and interesting collection of Rhopalocera 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 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. 



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 different from the usual type of Lepi- 

 dopterous ova. 



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

 had 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 

 out-door temperature. The latter insects were in all cases darker than the 

 former, all being equally healthy. Mr. McLachlan, Mr. Barrett, Mr. Jenner 

 Weir, and others took part in the discussion which followed. 



Mr. C. G. Barrett exhibited a curious variety of the male of Arctia 

 mendica, bred by the Rev. W. F. Johnson, of Armagh. 



Canon Fowler exhibited the egg-case of a species of Mantidae from Lake 

 Nyassa, and specimens of Bledius dissimilis, Er., from Bridlington Quay, 

 Yorkshire. 



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

 of the Diamond-back Moth, Plutella cruciferarum, which was very abundant 

 in gardens near Loudon, and expressed his opinion that the moths had 

 been bred in the country and had not immigrated. 



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

 recently seen specimens of Colias edusa in different localities near Loudon. 



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

 of Plusia gamma, and also on the appearance of a large number of Cynthia 

 cardui and other Vanessidae. 



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

 of Pseudacraa. — W. W. Fowleh. lion. Sec.
