Larvfe fed up under green muslin :— There was a tendency to kill 

 the yellow and orange, the former colour becoming more whitish 

 and the latter more orange yellow. 



During the seventeen years of the experiments there have been 

 112 broods, from 15,955 ova, producing 13,476 larvae and 10,095 

 imagines. 



Mr. Pickett also exhibited very long series of Aririades coridon 

 taken during the last four seasons in the Herts district, and show- 

 ing much extreme variation. There were included lovely specimens 

 of the ab. se^ii.si/iifirapJta, ab. viuqualis, ab. striata, ab. ohsoleta and 

 the newly differentiated asymmetrical gynandromorphic females 

 with one side smaller than the other, the smaller side always con- 

 taining some amount of androconial scales. One extreme aberra- 

 tion was a remarkable albino male whitish over the entire upper- 

 surface without dark margin, and another extreme aberration a male 

 with the black margin extending uniformly and widely round the 

 margins of the hindwings as well as of the forewings. 



The Rev. F. D. Motice exhibited a collection of British Chrysi- 

 didse and a collection of the more conspicuous species of Palaearctic 

 Chrysididie (non-British) and stated that this group of brilliantly 

 coloured Hynienoptera were parasitical on the wood- burrowing bees 

 and sand wasps. It was somewhat remarkable that the British and 

 many Palaearctic species were much more brilliantly coloured than 

 their tropical relatives. 



Mr. B. S. Curwen exhibited series of European parnassiids 

 Doritis apullinus, FarnassitiH apnllo, P. deliiis and /-•. iii ne)ti osijne Vi'ith 

 several aberrations ; series of Lycana arion, /.. areas, L. euphennis, 

 L. alcon and L. iolas with Polyomviatns aiiianda ; and several aber- 

 rations of Apatura ilia including ab. iliades taken near Laon in early 

 July of 1914. 



Mr. A. W. Mera exhibited a series showing the variation obtain- 

 able in Psiliira inonacha. The series included examples ranging 

 from typical forms to black specimens. They were bred from a 

 typical female crossed with a black male. The strain was origi- 

 nally from Ringwood and Morth Kent and has been interbred and 

 selected for some years. 



Mr. A. E. Tonge exhibited Aijriades thetis from Folkestone includ- 

 ing a female with large yellow lunules on the hindwings, and from 

 Reigate a very small male measuring only 22mm. ; specimens of 

 Polyoiiniiatiis icariis from Deal, Reigate, etc., including strong blue 

 females, ab. icarinns, ab. striata, etc. ; two salmon pink forms and
