JULY Vdth, 1911. 



Mr. Percy Harris, of Streatham Hill, was elected a member. 



Mr. A. E. Tonge exhibited ova of Manduca atropoa, dissected 

 from a captured female by the Rev. C. R. N. Burrows. They were 

 infertile, and now discolouring. The female laid one ovum, which 

 hatched out, the larva being about fin. long, pale green, with a 

 straight black caudal horn when received on July 3rd. He now 

 exhibited it in the third instar in which it had the lateral stripes 

 very boldly marked, and the caudal horn still long and straight. 



Mr. A. W. Dennis exhibited a photograph of a flower spike of 

 the bee orchis Ophn/s apifera, found near Reigate in June by Mr. 

 J. Winkworth, in which four of the flowers each had three lips, 

 other parts of the flowers being also in excess. The colour was 

 normal. 



Mr. Hy. J. Turner exhibited a spray of the lesser bladderwort 

 Utricnlaria minor. The plant was originally found by him in the 

 Cutmill pond, west Surrey, in the early autumn of 1910. He had 

 kept it in a glass jar in which he had placed a layer of humus and 

 decaying leaves, and which had been kept filled with tap water. 

 The plant dwindled in the winter to small branchless green balls, 

 which floated on the top of the water until the spring, when a 

 mass of branches with abundant bladders was produced. 



Mr. R. Adkin exhibited a series of Biston hirtaria from Aviemore 

 that had remained in pupa for three winters, and which showed 

 some unusual variation. He said, " When the late Mr. McArthur 

 was collecting in the neighbourhood of Aviemore, Perthshire, in 

 the spring of 1908, he met with a good many specimens of B. 

 hirtaria, some of which showed a certain amount of variation, 

 the most pronounced forms being a male of a greyish colour and 

 several females that Mr. McArthur described as " golden." During 

 the summer of 1908 I fed up portions of broods obtained from 

 some two or thrqip of the last named, and both in 1909 and 1910 a 

 few moths were reared from them, but there was nothing very 

 striking about them (" Proc. S. Lond. Ent. Soc," 1910, p. 110). 

 In the present year, however, the emergence took a much longer 

 time, some fifty specimens having come forth, and among them
