it is allied ; Satyrus actxa, var. cordula, captured last July at Sierra, having four 

 equal-sized pupilled eyes on the fore-wings, probably a local form peculiar to this 

 warm locality; a short series of Chrysophanus dorilis (type) and C. var. subalpina 

 from the Laquinthal, with P. Hippothoe, var. Eurybia, showing the strong resemblance 

 on the upper surface, which the ? of this latter species bears to the ? subalpina. 

 Mr. A. J. Chitty, specimens of a Proctotrupid which he said approached Poncra 

 constricta, Latr., in appearance, and might be an Isobrachium, Forst. If so, it was 

 new to the Bi-itish list. Mr. H. Willoughby Ellis, Criocephalus jjolonicus, Motsch., 

 a Longicorn beetle new to Great Britain, and also specimens of all stages from the 

 egg to the imago, to illustrate the life-history of the species which he explained. 

 The insects were taken in Scotch fir-trees this year in the New Forest. Also speci- 

 mens oi Asemum striatum, L., with larva and pupa, accounted heretofore rare in the 

 New Forest, but this year occurring in abundance. Mr. Ambrose Quail, cases 

 showing the life-history of some Australian Hepialidse. Mr. Roland Trimeu, 

 F.R.S., some cases of mimicry between butterflies inhabiting the Kavirondo-Nandi 

 district of the Uganda British Protectorate, particularly that in which Planema 

 Poggei, Dewitz, is imitated by an apparent variety of Pseudacrxa Kiinowii, Dewitz, 

 and also by a hitherto undescribed form of the polymorphic ? Papilio Merope, Cram. 

 This he said makes the fourth pronounced known form of the ? Papilio Merope. 

 The usual and generally distributed form of this sex throughout Tropical Africa is 

 that named Svppocoon, by Fabrieius— an excellent mimic of Amauris niavius, L. ; 

 all the other forms appear to be very rare, and two of them — Dionysos, Doubl., and 

 the form from Zanzibar described in the Presidential Address to the Society on 

 on January 19th, 1898— are not direct mimics of any other butterflies, but are least 

 divergent from the non-mimetic coloration and pattern of the male. The form now 

 brought to notice is, on the contrary, a direct and unmistakable mimic of Planema 

 Poggei ; and, as it is inconvenient to refer to the mimetic forms without assigning 

 names to them, Mr. Trimen proposed to style this form planemoides. The President 

 congratulated Mr. Trimen on the exhibit, and the special interest attaching to an 

 interpretation of this remarkable form of the female Merope. At the same time 

 he pointed out that the interpretation so convincingly illustrated that evening had 

 been made out last spring by Mr. S. A. Neave, who exhibited this form of the 

 female Merope together with Planema Poggei as its model at both soirees of the 

 Royal Society in May and June, a time when Mr. Trimen's absence from England 

 unfortunately prevented him from seeing them. Dr. T. A. Chapman, Caenonympha 

 (Edipus, Satyrus Dryas,a.nd Seteropterus Morpheus, taken last summer near Biarritz ; 

 and Erebia evias and Erebia stygne, from the Logroiio Sierra, Spain. These, 

 respectively, he suggested were probable examples of homoeochromatism. Little 

 attention has been directed to homceochromatism in European butterflies, and these 

 were certainly not examples of the detailed mimetism we are now familiar with in 

 Miillerian groups from the African and neotropical regions. Also living imagines of 

 Crinopteryx familiella. These had just emerged at Reigate, where they and their 

 parents, descended from pupa; brought from Cannes in March, 1901, had lived out 

 of doors during their active existence, being brought into the house only during 

 their pupal ffistivation. This seemed noteworthy in so southern (Mediterranean) a 

 species. The experiment seemed quite likely to continue successful for the next 

 generation.
