statement was incorrect. I have no doubt that Kaltenbach 

 is perfectly right in stating that C. cosmophorana makes a 

 nodule similar to that oi R. resinella. But I have no hesita- 

 tion in saying that the larva of C. cosmophorana, so far as 

 Scotland is concerned, does not feed in the way described 

 by Kaltenbach. If C. cosmophorana does cause these resinous 

 nodules to form, surely such would have been observed in 

 the district where this species occurred. Now R. resinella 

 has been searched for in the Rannoch district by many 

 collectors who are well acquainted with its habits, and so 

 far as I am aware without success, which proves to my mind 

 that even in Rannoch C. cosmophorana feeds in a different 

 manner from that described by Kaltenbach, otherwise the 

 nodules would have been found and probably ascribed to R. 

 resinella. So it would seem that in districts no farther apart 

 than Rannoch and Forres the habits of the larva must be 

 different- That the refuse in the nodules of R. resinella is 

 not the normal food I am convinced. But of this I am 

 certain, that the C. cosmophorana larvae which I found at 

 Forres were feeding on the frass in the deserted nodules 

 made by R. resinella.'' 



A long discussion ensued, Messrs. Adkin, South, Barrett, 

 Fenn, and McArthur taking part. So far as the evidence 

 went, it seemed probable that C. cosmophorana had different 

 habits in different localities. Its actual life-history was 

 certainly unknown. A suggestion was made that the frass 

 of R. resinella was very little altered, and thus available as 

 food for C. cosmophorana. 



Mr. Billups read a paper on " Dipterous and Hymenop- 

 terous Parasites reared from Lepidopterous Hosts by 

 Members of the Society during the Years 1891-2 " (printed 

 in full, pages 80-87), in which he mentioned some 480 

 species of parasites from 361 hosts, and exhibited a large 

 number of parasites, with examples of the caterpillars they 

 infested.

Col. Partridge exhibited three bred specimens of Phigalia 

 pedaria {pilosaria) from Epping Forest ; they were of a 

 singular unicolorous grey colour with dark nervures, having 

 thus assumed one of the characters of the dark northern 

 form ; a specimen of Agrotis puta, with alternate dark and 

 pale bars, which form, Mr. Tutt said, was occasionally found;
