hibernation. They came to the surface and burrowed again'. An 

 attempt was made to force the larvse in the autumn, but it failed. 

 The pupte are about two-thirds the usual size. The larvfe were 

 nearly black when fall fed. 



Spilosoiiia iiienthastri ova were found by him on the shell of a 

 living snail in July, 1910. 



Several batches of ova of Hadena pisi were found on a small 

 plum tree. The larvae did not appear to feed on the leaves of the 

 tree but descended to the ground, and were found on knotgrass and 

 narrow-leaved plaintain in July, 1910. 



Mr. Newman said that the larvse of A. hispidaria pupated 

 readily in two inches of soil, if placed so that a hard concrete floor 

 formed the bottom of the cage. By this treatment he had readily 

 bred the species, and not two per cent of cripples emerged. Several 

 members remarked that this species was very prone to produce 

 cripples in nature. 



Mr. Eobert Adkin exhibited two varieties of Arctia caia, both 

 from Yorkshire larvae. One reared in July 1909 had the whole of 

 the forevvings of a dull smoky-brown with two irregular whitish 

 markings at the base, the lower somewhat triangular in shape ; a 

 <;onstricted white streak across the inner area from a point within 

 the costa to near the anal angle ; between this and the apex three 

 small white spots, and there were two similar spots near the inner 

 margin ; the hindwings were black with basal patches, and broad 

 fringes of dull yellow ; there were also some ill-defined yellow spots 

 on the central area. The other, reared July, 1910, had the 

 forewings dead white, with the usual markings of the basal two- 

 thirds indicated by small brown irregular shaped spots, and the 

 apical portion of the outer margin heavily marked with brown ; 

 the hindwings were bright orange-red, the inner spot indicated by a 

 black dot on a yellow cloud, and the three outer black spots reduced 

 in size and edged with pale yellow. 



He also exhibited living females of Nyssia zonaria with eggs in 

 situ under the bark of donatio.

Miss Maude Alderson, F.E.S., of Worksop, was elected a member. 



Mr. W. J. Ashdown exhibited about 100 species of Coleoptera, 

 taken in Switzerland during July, 1910, including : — Enuis hirtus, 

 Gnoriiiins nohilis, Liidiiis Juniiatodes, Homalisiin suturali.s, Lyt/istopterus
