Exhibitions. 



A DiPTERON ASSOCIATED WITH AnTS. — Mr. DONISTHORPE 



exhibited a larva and pupa cases of a species of Microdon 

 (either M. latifrons Lw., or near to it) which he had found in 

 the galleries of Acanthomyops {Donisthorpea) 7iiger L., in 

 stumps of Scots pine in the New Forest on May 6 and 11, 

 1922 ; also a pupa case of true Microdon latifrons from Woking, 

 larvae and pupa case of M. mutabilis from Porlock, and an 

 imago of M. devius from near Oxford. He mentioned the 

 British distribution of M. latifrons, and also said that Father 

 Wasmann had told him that the pupa cases he had sent to 

 the latter from the New Forest were M. rhenanus Andries, a 

 species new to Britain. 



A RARE British Tortrix. — Mr. W. G. Sheldon exhibited 

 three specimens of a rare British Tortrix, Hedya sifnplana 

 F. von R., from Kent. These were the only examples taken 

 or seen by him in a fortnight spent in the locality. 



HoMOEOSis in Butterflies. — Dr. E. A. Cockayne ex- 

 hibited : — 



(1) Two examples of homoeosis in Coenonympha pamphilus 

 L., taken by Mr. H. A. Leeds in 1922. The first, a male from 

 Kent, has a number of patches of the tawny colour of the 

 underside of the fore-wing on the underside of the right hind- 

 wing. These patches have scales like those of the fore-wing, 

 and are devoid of hairs. The second, a male from Monk's 

 Wood, Hunts, has areas with the colour, and with the scales 

 and hairs of the underside of the hind-wing on the underside 

 of the right fore-wing. Both have the upperside and neuration 

 normal, and show no sign of injury.
