had quite 50 per cent, ichneumoned. This I put down to 

 the backwardness of the season in the earher part of the 

 year, which delayed the emergence of the ichneumon fly, as 

 they were only just out when I was taking this year's pupae, 

 and I frequently came across last year's pupse with the fly 

 ready but not yet emerged. They also seemed subject to 

 attack by earwigs, spiders, and woodlice, which, after eating 

 the pupas, take up their abode in the cocoons. Some of last 

 year's pupai in my cages produced ichneumons in the second 

 week in June. My lirst B. muralis emerged on July 17th 

 and the last on August i6th, although I took thirteen fresh 

 specimens, drying their wings on walls in the Isle of Wight, 

 on August 2 1 St. "' 



Mr. Lucas exhibited a series of nine specimens oi Libellida 

 qnadriuiaculata, showing a complete gradation between the 

 type form and an extreme example of the variety prcBimbila. 



Mr. Chittenden exhibited the following captured or bred 

 varieties, mostly from Kent: — Noiieophila plaiitaginis, with 

 red under- wings, van hospita ; Spilosoina Inbvicipcda, var. 

 radiata, eburac i, titc, bred; Spilosoina uienthastri, var. one 

 with buff fore-wings ; Phigalia pcdaria (^//osana), two blackish 

 varieties ; Boaruiia repandata, hldick variety ; Bupalus piniaria, 

 right side female colour, left wings male colour; Abraxas, 

 grossulariata, dark varieties ; Hybevnia marginaria {pvogeui- 

 uiavia), and var. fuscata ; Cheimatobia brumata, with small 

 hind wing ; Lobophora carpiiiaia (lobulala), banded form ; 

 Larentia ccesiata.ddivXi and banded forms ; Hypsipetes sovdidata 

 {elutata), reddish and light varieties ; Cidaria triuicata {russata), 

 red and white varieties; Cidaria ivinianata, dark and light 

 varieties. ; Xylophasia uionoglypha, black and light forms ;

 Tccniocampa niunda, one with no spot ; Orthosia suspecta, red 

 varieties ; Ccrastis vaccinii, dark ; DianthcBcia nana (conspersa), 

 a dark variety; Aplecta prasina (herbida), dark and light 

 variety ; Drepana falcataria (falcula), brown varieties. 



Dr. Chapman exhibited a few £'ri:5/a.s collected this season, 

 to illustrate how, in the genus, the most well-marked forms 

 tend to have black spots with white pupils in each 

 marginal wing cell, set in a bright brown or rust-coloured 

 band, which may invade a large part of the wing, and in the 

 other extreme, the dark ground colour may cover the whole 

 wing to the exclusion of all spots or rust colour. E. glacialis 

 perhaps covers in one species the widest range in this
