taken at Chalfont Road, Bucks, in which the apical oceUi 

 were wanting ; a bleached variety of the same species, 

 taken at Swanage, Dorset ; and a bleached variety of 

 E. tithonus, taken near Cromer, Norfolk, with normal 

 specimens for comparison. 



Mr. C. Nicholson exhibited a specimen of Catocala sponsa 

 having the left upper wing entirely suffused with umber 

 brown, the right wing being of the grey and ochreous-brown 

 form ; the left hind-wing was rather dwarfed. Two speci- 

 mens of a brood of Pnrarge egeria, bred from Dawlish 

 eggs. One of the specimens was ver}^ thinly scaled 

 and the markings obscure ; the other was not so thinly 

 scaled and the markings were almost normal. As the 

 remainder of the specimens bred were small and seemed 

 very weak, it was probable that the aberrations were due to 

 bad nutrition. A bred female specimen of the summer 

 brood of Pieris rapce having a somewhat indistinct dark spot 

 on the disc of each hind wing. A bred specimen of Geo- 

 metra papilionaria from the New Forest, the green colour 

 having been apparently bleached out of each hind-wing from 

 the hind margin to about the centre ; other specimens bred 

 from the same brood were normal. A specimen of Mamestra 

 brassicce in which the whole of the fore-wings was of a 

 uniform leaden-grey colour, rather shiny ; the subterminal 

 line and stigmata being lighter and tolerably distinct. The 

 specimen was captured at treacle in the exhibitor's garden 

 at Clapton. A series of Melanippe fluduata, also from 

 Clapton, two being clearly banded with dark and light 

 grey, like M. sociata, and the other two having the central 

 band reduced to a wedge-shaped costal blotch ; in one of 

 the two this was very small. 



Mr. A. F. Cole exhibited a Catocala nupta, var. cccrulcscens, 

 similar to the specimen exhibited by Mr. Winkley. It was 

 caught at sugar at Brondesbury. He also exhibited a 

 variety of Colias hyale having a broad elongated splash of 

 black on the under side of the fore-wings. It was caught 

 near Great Missenden, Bucks. 



Mr. Kirkaldy exhibited a large number of specimens in 

 illustration of colour variation in Notonccta, and contributed 

 the following note : 



" The species of Notonccta are the most brightly-coloured 

 of water-bugs, but in this genus colour is almost entirely 

 unreliable, although a red and black abdomen in A^. insn- 

 lata, and a yellow and black one in N . glauca, var. macnlata, 

 seem to be distinctive of these forms. In many species,
