stirred and were changing their skins. These larvpe moulted 

 immediately before hibernation, the bright green colour being 

 replaced by straw colour, and they moulted again in spring before 

 commencing to feed, their colour becoming again green. In this 

 species a certain percentage always go through a second winter, 

 especially when an early spring has called them up and this is 

 succeeded by a cold spell, when they go into retirement until the 

 following spring. 



Mr. Hy. J. Turner exhibited a male and a female of the race 

 hibernica oi Kucldo'e cardauiincs from Co. Tyrone, Ireland; it was 

 characterised by being somewhat smaller than the type, the more 

 strongly marked ends of the Aving nervures, and in the female the 

 strong suffusion of the hindwing with yellow. The female 

 exhibited was of the form ab. ranlnsficta in which the discoidal spot 

 was very large and branched, extendmg along the costal area of the 

 forewing upperside. Another example was ab. citronea in which 

 the basal portion of the forewing below was suffused with yellow. 



Mr. Turner also showed three forms of the South African Pierid 

 butterfly Kronia dendora, the type form with narrow black margins, 

 the form dilatata with broad black margins and paler yellow below, 

 and the intermediate form eiwia with still paler underside, with 

 marginal band of medium width. 



Mr. Parmer reported the abundance of Abraxaa (jroasidariata 

 larvie which were feeding and pupating at the present time. 



Mr. B. S. Williams recorded the unusual occurrence of Pachys 

 (Amidu'dasis) strataria {prodroinaria) at Finchley. Mr. Tonge said 

 that the species usually rested high up on the trunks. Several 

 members noted that in the afternoon the species might be found 

 low down, probably just emerged.

Miss L. E. Cheeseman, F.E.S., read a short paper entitled "The 

 Parasite of Sirex. (ii'iiaa, PJu/s.sa persna^nria," and illustrated it with 

 lantern slides. (See page 1.) 



Mr. Edwards exhibited specimens of Hlnjasa jHTsitasoria from 

 the British Isles and the continent. 



Mr. Hugh Main exhibited some beetle {Geotnipcs sp.) larvffl 

 found in a manure heap and described their movements and the 

 economy of the beetle. He also suggested that in this species
