plant Ccntaurea solstitialis, or yellow knapweed, an alien from 

 the Mediterranean region. It was found in a new road in 

 Chiswick. Mr. Step said that some years ago he had 

 received specimens of this plant found by Mr. Adkin at 

 Eastbourne. Its seeds are thought to be introduced with 

 those of lucerne, as it is chiefly found in fields of that plant 

 in the southern and eastern counties. 



Mr. W. West (Greenwich) exhibited the following species 

 of Hemiptcra from Esher : Salda cocksii, Cyrtorrhinus pygmceus, 

 C. caricis, and Nabis boops, together with Bvyocoris pteridis 

 from Carlisle. 



Mr. B. H. Smith exhibited ova of Porthesia chrysorrhcea in 

 the covering of abdominal hairs of the female found on sea- 

 buckthorn {Hippophac vhamnoides) at Deal. 



Mr. Step, on behalf of Mr. Carr, exhibited a variegated 

 form of Scnccio jacobcea from Box Hill. 



AUGUST 2jth, 1908. 



Mr. Robert Adkin exhibited two short series of Dictyopteryx 

 bevgmanniana reared, the one from pupae taken on a cultivated 

 rose tree, the other from larvae feeding on burnet rose. The 

 former, he said, had much distorted the leaves of the culti- 

 vated rose, thus forming conspicuous bunches of them ; 

 whereas the larvae in the smaller leaves of the burnet rose 

 had drawn them so neatly together that their presence was 

 not easily discernible, and the puparium was equally incon- 

 spicuous. He thought the larvae in the wild species of food 

 plant followed their natural habit, and that those in the 

 cultivated rose found a difficulty in dealing with the much 

 larger leaves of that plant, and thus rendered their presence 

 unusually conspicuous. 



Mr. Hy. J. Turner exhibited a specimen of Crambus 

 chvysonuchcllus from Eastbourne, in which the lighter mark- 

 ings were all slightly broader than in normal specimens 

 taken in various localities on the North Downs, giving the 

 specimen a whiter appearance. He also showed two forms 

 of Eurrhypava urticata, in one of which the usually coalesced 

 spots, forming the marginal band on all four wings, were 

 much diminished in size and well separated, while in the 

 second the same series of spots were enlarged and elongated, 

 forming a complete marginal band and almost obliterating 

 the space between the two dark bands ; the rest of the dark
