had also taken a specimen, attracted by the same lamp, in 

 October, 1903. 



He also showed eight specimens of Euchloe cardamines, 

 reared from ova found on hedge mustard (Sisymbrium 

 officinale). The larvae were supplied throughout with wall- 

 flower — the green seed-pods especially. Variation in size of 

 the specimens was curious. Two females measured 50 mm. 

 each in expanse, whilst one male and one female did not 

 exceed 35 and 36 mm. respectively. 



On behalf of Mr. H. C. Hayward, of Repton, Burton-on- 

 Trent, Mr. South exhibited a remarkable and very rare 

 aberration of Cabera pusaria. In this example the wings 

 were leaden-grey in colour and the transverse lines com- 

 pletely eliminated, the only trace of the normal white in 

 evidence being on the head and thorax, the latter tinged 

 with grey. The specimen, which measured 28 mm. in expanse, 

 was taken at Repton in July last. Mr. Hayward had also 

 sent a box of moths showing a distinct melanic tendency in 

 some of the species he obtains in his district. Among these 

 were two forms of Xylophasia monoglypha ; one of these, 

 which was quite abundant in 1905, approached the darker 

 Scotch forms ; the other, also dark, but variegated with 

 reddish-brown, occurred more sparingly. Exceedingly dark, 

 almost black, examples of Tceniocampa inccrta ; one of these, 

 with the stigmata outlined in whitish, was stated to be the 

 most common. Two forms of Hadcna dissimilis (suasa), one 

 reddish-brown, and the other blackish-brown with a faint 

 greyish suffusion ; the former occurs at Repton almost as 

 commonly as the type, but of the latter only one example 

 had been seen. One example of Noctua xanthographa was 

 of an unusual fuscous brown colour, the central shade 

 blackish, and the stigmata finely outlined in pale ochreous. 

 A smoky-grey specimen of Cymatoplwra duplaris, in which 

 the only markings at all in evidence were the black discal 

 dots. A rather glossy, greyish-brown example of Grammesia 

 trigrammica with very faint traces of transverse lines, and 

 having a reddish suffusion on the outer third. Three speci- 

 mens of Tephrosia crepuscularia ; one of these, representing 

 the dominant form of the species at Repton, had all the 

 wings rather thickly sprinkled with blackish, but the lines 

 were fairly distinct ; the second was more heavily powdered 

 with blackish, and the lines, except the white submarginal, 

 were indistinct ; the third was sprinkled with blackish and 

 suffused with brownish, the lines being pretty much as in 

 number two. These forms of T. crepuscularia are somewhat
