Mr. Tonge exhibited photographs of the cocoons of 

 Dicranura bicuspis previously exhibited by Mr. Newman, and 

 also of the larva oi Char axes j asms, showing the peculiar con- 

 formation of the head, together with a pupa of the same 

 species showing very clearly the prominent pad from which 

 it is suspended. 



Mr. West, of Greenwich, exhibited the Coleopteron, 

 OxylcBinus variolosus, sl rare species taken at Darenth Wood 

 on August 2nd, 1903, and till now overlooked. This species 

 is also rare on the Continent, where it was first taken by 

 M. Dufour under bark of oak in a high mountainous district, 

 and afterwards by Herr Grepner, in Saxony, in company with 

 Formica fuliginosa. 



Mr. B. W. Adkin exhibited the following forms : 



Enpiihecia pumilata, a varied series, including a New 

 Forest specimen with practically only two transverse lines. 



Anaitis plagiata, a curious bandless form, and one with 

 confluent bars. 



Cidaria siterata, a few nicely varied, well-marked forms. 



Eubolia plumbaria, examples in which the dark margins of 

 the central fascia gradually widen until they coalesce and 

 form a dark inner-marginal blotch. 



Camptogramma bilincata, several specimens from Scilly, in 

 which the bands were very dark-edged, with a much lighter 

 interior ; in others the general area of the wings was darker 

 than usual, and in two specimens the hind wings were very 

 dark. 



Mr. R. Adkin exhibited a series of Cymatophora duplaris, 

 from Rannoch, which comprised two very distinct forms ; 

 one of a smoky grey colour, with the basal patch and 

 transverse lines pale and distinct ; the other of an almost 

 uniform dark smoky shade, with the basal patch and 

 transverse lines obscurely indicated in a paler greyish tone. 

 He said that in former series, received from the same locality, 

 the first-mentioned form only had been represented, but in 

 the case of the present series the proportions were as six of 

 the paler to four of the darker. Tutt, in "The British 

 Noctuse and their Varieties," vol. i, p. 5, mentions a form 

 under the name of var. obscura, as occurring at Rannoch, of 

 which he says : " The anterior wings are of an almost 

 unicolorous leaden grey, with faint traces of a base and 

 subterminal line, being almost as melanic as the type." 

 The Linnaean type is said to be unicolorous without any 

 trace of paler transverse lines. The darker specimens of the 

 series exhibited, he thought, must be referred to the var.
