subject, and was still of opinion that the specimens were 

 simply T. viburnana. Mr. Carpenter had written him that 

 although the larvae fed on pine, one example had fed equally 

 well on Vaccinimn. 



Mr, Tutt exhibited the series of Tortrix steineriana var. 

 dohrniana, sent him by Herr Hoffman, and stated that the 

 male showed the usual unicolorous character of the male of 

 this particular group, the females being very concave on the 

 costa, and varying from almost unicolorous to a well-developed 

 central band. He also exhibited specimens of T. viburnana, 

 from Darlington and Ar.nagh, both sexes of T. paleana, Hb., 

 specimens of the marsh species, which he said was probably 

 the aspJiodilana of Herrich-Schaffer, and supposed to be 

 synonymous with unicolorana, Dup., from the Essex marshes. 

 Mr. Tutt remarked that in this part of the genus there were 

 some six or eight species very closely allied, and it was 

 difficult to separate these after studying the variation among 

 them, and he added tliat the figure published by Mr. Carpenter 

 was undoubtedly that of steineriana. He did not suggest 

 that Mr. Barrett was not rigiit in calling the Irish specimens 

 viburnana ; but until more material was obtained, he did not 

 think it could be assumed they were distinct from the Conti- 

 nental 7". steineriana var. dohrniana. 



Mr. Barrett remarked that Mr. Carpenter's figure was from 

 a single specimen, and was extremely unlike the majority 

 which had since been bred.

W. H. TUGWELL, Esq., Ph.C, President, in the Chair. 



Mr. J. A, Cooper exhibited five specimens of Arctia caia, 

 L., the red colour in the inferior wings being replaced by 

 yellow. Mr. Cooper remarked that from some thousand 

 larva; collected near Wanstead Flats, Essex, seven of this 

 form of the insect were bred, the whole of them emerging in 

 one day ; the larvae were fed under usual conditions, and as 

 far as he could say there were no atmospheric conditions 

 which would account for the variation. 



Mr. Tugwell called attention to one of the specimens 

 having the fringe of the inferior wings almost entirely black ; 

 he had lately looked over about one hundred specimens, and 

 only found one with a black fringe. 



Mr. Carrington said he, in company with Mr. Briggs, 

 recently when going through the late Mr, Bond's collection, 

 noticed that in the series of about forty caia, there were only 

 six with dark one with buff, and the rest with light antennae ;
