Dr. Buckell remarked on M. ocellata, Core/niaferrugafa, C. nnideniaria, 

 C. propugnata, and C. mutiitata, whilst Messrs. Clark, Milton, and 

 Battley took part in the discussion which followed ; and a vote of thanks 

 was accorded to Mr. Tutt for his paper. An interesting discussion also 

 took place respecting the effect of the recent severe frost on aquatic 

 coleoptera and fish. Mr. Milton stated that he had found large 

 numbers of dead beetles in the shallow pools at Clapton ; but in the 

 deeper ponds they appeared to have survived. Several members had 

 observed dead fish floating on ponds and lakes, the oxygen in the water 

 having apparently become exhausted. — G. A. Lewcock and A. U. Batt-

South London Entomological Society. — January 227id. — Mr. 



South exhibited typical specimens of Miana strigilis and M. fasciun- 



cula, and pointed out the following superficial differences between the 



type forms : — (i). That of colour; (2). the difference in stigmata, those 



of fasciuncula being often absent ; (3). the more stumpy shape of 



fasciuncula ; (4). the underside of strigilis grey, that of fasciuncula 



ochreous ; (5). the presence of crested tufts on the abdominal segments 



in strigi/is, and their apparent absence in fasciuncuia. Mr. Tutt exhibited 



the specimens of Miana from Armagh, and others, for comparison. With 



regard to Mr. South's remarks, he pointed out (i). that the colour of the 



Irish specimens proved that it was entirely unreliable ; (2). with regard to 



the stigmata the variation was equally marked in typical strigilis and 



fasciuncula ; (3). that some of the strigilis exhibited were as stumpy as any 



fasciu?icula, (4). that the crested dorsal and abdominal tufts, though perhaps 



a little more distinct in some strigilis, owing to the darker colour, were 



equally well developed in both (as the specimens exhibited proved); (5). 



that considering the great difference in coloration of typical strigilis 



and fasciuncula it was not sur|)rising that the underside of the former 



was blackish-grey, and of the latter ochreous-grey. He also pointed 



out that Mr. Atmore and himself had spent some time in examining the 



long series in his cabinet, and that there was no single reliable point of 



distinction in structure and markings. Mr. Fenn expressed an opinion 



that all the Armagh specimens were dark fasciuncula, Mr. South that 



two were strigilis and the rest fasciuncula. Other members considered 



that three of the specimens were referable to strigilis, the others to 



fasciuncula. Mr. Tutt agreed with all these different views, as he 



thought the questionable specimens might (as he first stated) with equal 



propriety be called strigilis or fasciuncula. He also called attention to 



the fact that four descriptions of the larvie of strigilis were in existence 



and all were different, and that reliable information was much needed. 



Mr. Fenn, whilst expressing an opinion of the general distinctness of 



strigilis and fasciuncula, said that it was absurd to rely on the dorsal 



abdominal tufts as a character by means of which to separate them, and 



suggested that these were developed in both species. His experience 



pointed to a difference in the time of flight ; but Messrs. Tugwell and 



Tutt had found the species flying together until the middle of July. It 



was also remarked that the Armagh specimens in question were all 



taken on one date. Mr. South also exhibited an apparently extreme 



form of strigilis, which he thought might be a distinct species. Mr. 



Short exhibited specimens of a pale whitish var. of Hepialus lupulinus, 



females of Pencallia syringaria, and Chrysophanus phlceas ; Mr. Tug-
