Mr. H. McArthur exhibited a specimen of Tcsniocampa 

 gothica, L., v?iX,gothicina, H.-S,, and asked if he was correct in 

 his determination. Mr. C. G. Barrett replied that the specimen 

 was undoubtedly the true vas.gothicina. Mr. McArthur also 

 exhibited specimens of Coccyx cosmophorana, Tr,, and Retinia 

 duplana, Hb., from Forres, N.B., and suggested that the 

 latter insect was imported with the Scotch fir from Norway ; 

 but Mr. Barrett remarked that the Scotch fir was indigenous, 

 and that all the original specimens of so-called R. duplana 

 were small specimens of R. turionana, Hb. Mr. J. W. Tutt 

 remarked that R. turionana was only taken every alternate 

 year, and Mr, McArthur suggested that the species required 

 two years to pass through its various stages. 



Mr. J. M. Adye exhibited a fine and variable series of 

 Boarmia repandata, L., including some banded forms (var. 

 conversaria, Hb.). The specimens were taken at sugar in the 

 New Forest during July, 1892. 



Mr. J. Jenner Weir drew the attention of the Society to an 

 illustration in Insect Life for January, 1893, p. 206, reduced 

 from a photograph, of Anosia plexippus, L., showing about two 

 dozen of the insect closely packed together on the small 

 branch of a tree, and read the following notes: — "It appeared 

 that last September millions of these beautiful butterflies had 

 been seen at Oklahoma, journeying from north to south, 

 resting at night in immense swarms, as shown in the photo- 

 graph, which had been taken with the aid of the electric light. 

 All the evidence obtained proved almost to a certainty that 

 this insect was migratory, precisely in the same manner as 

 many species of birds ; the subject had been admirably dealt 

 with by Mr. Scudder in his valuable work, The Butterflies of 

 the Eastern United States and Canada^ in which he records 

 several instances of enormous autumnal flights of the butterfly 

 from north to south, and also several flights from south to 

 north. The object he had in view in bringing the interesting 

 habits of this wandering butterfly before the Society was not 

 only because of late years it had become an occasional visitor 

 to the southern parts of this country, but also to compare its 

 migratory habits with those of Colzas edusa, Fb. It was 

 quite clear that the latter species migrated in certain years 

 to England from the Continent in considerable numbers, that 

 these visitors were hybernated imagines from more southern 

 latitudes, that one or two broods were produced here during 

 the year ; but there was no proof that the perfect insect ever 

 hybernated in this country, nor that there was an autumnal 

 migration to the Continent on the approach of cold weather ;
