Exhibitions. 



Mr. H. St. J. Donisthorpe exhibited a parasitic Braconid 

 bred from galls of Ceuthorrhynchus sulcicollis, on turnip, 

 together with the host. 



Mr. A. J. Chitty exhibited a variety of Psylliodes cyan- 

 o])tera, 111., the coloration of the thorax being dark instead 

 of the usual red colour, taken by him along with the typical 

 form in August 1892, at Wicken Fen close to the Pumping 

 Station. 



Mr. H. J. Turner exhibited a long series of Bryophila 

 muralis (glandifera) from Dawlish. The whole were either 

 taken on, or bred from pupse cut out of, a single roadside wall 

 some hundred yards long, very lofty, and facing nearly north, 

 on which aspect however it was protected by higher ground. 

 They were obtained in mid- August, with the exception of a 

 few which emerged at intervals during September and October 

 1900. Generally speaking the specimens were very dark, and 

 the series was remarkable in that it contained but a few isolated 

 examples of the forms which are prevalent in more eastern 

 localities like Freshwater, Eastbourne, or Folkestone. The 

 hind-wings of all the specimens were dark, while, in the 

 majority, the black markings of the fore-wings were much 

 intensified and increased in number, and a few specimens were 

 largely suffused with black. A considerable number showed 

 a dark rich green suffusion, while a large proportion were of 

 a very deep yellow or olive colour with black markings. The 

 yellow forms were perfectly natural, as a number emerged 

 from the pupa exactly of that hue. Only a few showed any 

 trace of the typical delicate dove-colour of the eastern forms. 

 The dwarfed specimens all emerged late in September or early 

 in October, and it was suggested that the larvae of these were
