JA^UAnY \2th, 1922. 



Mr. E. J. Bunnett, M.A., F.E.S., Vice-president, in the chair. 



The deaths of Dr. T. A. Chapman, F.R.S., Mr. J. Jager, and 

 Mr. R. Woolacot were announced. 



Messrs. A. S. Buckhurst, of Souldern Road, W., W. H. Bell, of 

 Wood Green, L. E. Couchman, of Hampstead, and Colonel R. A- 

 Rattray, of Tonbridge, were elected members. 



Mr. A. A. W. Buckstone exhibited Hdiophobus hispidus, from 

 Torquay and Dorset, pointing out that the extension of the narrow 

 pale submarginal line in the general dark form of the race from 

 Torquay, wiping out the usual dark marginal line, helped to 

 accentuate by comparison the paleness of the race from Dorset. This 

 pale form never occurred at Torquay. He also showed an extremely 

 dark aberration of OrthoUtha plninharia, from Headley. 



Mr. C. L. Withycombe exhibited larvae of the Dipteron Taenia- 

 rlu/nciis {Man:^niua) rlckardi, living and dead, with photographs 

 showing the way in which they attach themselves by their siphons 

 to a root of Tupha an;/ nsti folia to obtain a supply of air, a position 

 they retain the whole winter. He pointed out the barb on the 

 siphon which made it difficult for the larva to withdraw it. He 

 stated that the curious tail fin was used to drive in the siphon. 

 These larvffi were taken in Epping Forest on the submerged roots 

 of T. aminati folia, about a dozen being obtained from half a dozen 

 roots. The larvte were described for the first time in Europe by C. 

 Wesenberg Lund, in Denmark, in 1918. In the " Ent. Mo. Mag.," 

 in 1919, Mr. F. W. Edwards described larvae taken in England. 

 The pupa of the European species has apparently not yet been 

 described. 



Mr. Main said that numerous beetle larvae were known to tap 

 roots in this way. 



Mr. Bunnett stated that the larvf^ of Donacia sps. had a similar 

 habit. 



Mr. H. J. Turner exhibited the following interesting aberrations 

 sent to him by Mr. Thomas Greer, of Stewartstown, Co. Tyrone, 

 Ireland : — 



Kiichloi' cardaniines. — (1) ^ ab. iiian/inata, (2) ^ with orange 

 blotches streaked with dark scales, (3) <? ab. minor, (4) (? very 

 large, (5) $ ab. radiata, (6) ? with orange streaks above and 

 below. 



Melitaea aurinia. — ? of a dull, obscure coloration.
