extremely dark-banded forms of Ennonun c/uercinaria, and some 

 melanic forms from Kegent's Park, together with a pair of extremely 

 light forms from the Chiltern Hills. A bred series of Leiicania 

 ritellina from a female taken in N. Cornwall, in September, 1920. 

 A specimen of Papilio niachaon, taken in Whittlesea Mere on Jnly 

 23rd, 1819, in perfect condition, and of very good coloration con- 

 sidering its age. A fine silvered variety of Brenthu aelene from 

 Sussex. Haiiiearis Incina with the usual tawny markings replaced 

 by ochreous. A remarkable specimen of liinuicia j/hlaeaa with the 

 hindwings coppery, and showing the usually suppressed black spots. 



Prof. Poulton called attention to the fact that E. /ihlaeas of the 

 same facies as the coppery hindwinged example just exhibited, had 

 recently been recognised coming from Central Africa. 



Mr. Hammond exhibited an extremely dark specimen of the 

 calliDuie form of [Msiocanipa (jiiern'ts, the band being absent. 



Mr. A. A. W. Buckstone exhibited a series of Vcowssa in bred 

 last July from full fed larvae taken at Headley, Surrey, on June 

 25th. It was pointed out that there was a dark shade, and in some 

 specimens even a black spot, in the centre of the forewing. It was 

 suggested that these aberrations had been caused by the extremes 

 of temperature to which the larvae were undoubtedly subjected. 

 During mid-June the days were abnormally warm and the nights 

 exceptionally cold, several degrees of frost being recorded on five 

 successive nights. Forty-two specimens emerged, only twelve of 

 which were typical V. io. 



Mr. Buckstone also exhibited living larvfe of Paranie meijera, 

 and stated that on several occasions ants were observed running 

 over and about a number of these larvas which were confined in a 

 cage. He suggested that they may have been endeavouring to 

 obtain a substance from the protuberances situated on the anal 

 segments of the larvae. 



He also showed a series of Bnaniiin coiisortaria varying in colour 

 from dirty yellow to dark smoky grey. They were bred from ova 

 obtained from a moth captured at Wimbledon, in May, 1920, which 

 was somewhat similar in appearance to a specimen now exhibited. 

 Emergence took place during last February, the pup^ having been 

 forced and subjected to considerable variation of temperature. 

 More usual forms were shown for comparison. 



Mr. A. V. Pickett exhibited a large number of aberrations of 

 A<iri(iili'fi roi idon obtained by him during the last season. 



Mr. 0. R. Goodman exhibited six cases containing typical speci-
