opus hyperantus, and Arctia caia, many being from the collection of 
the late Sydney Webb. Mr. W. Mansbridge showed a long series of 
Leptogramma literana and its varieties from the New Forest, and a 
series of Elachista magnificella from near Prescot. . 
March 15th, 1920.—Parer.—Mr. F. N. Pierce read a paper entitled 
“Notes on American Tortrices.”’ In his interesting communication 
Mr. Pierce described the affinities of a small collection of North 
American Tortricidae, with certain British species, as shown by their 
genitalia, and exhibited the specimens. If there were any longer 
doubt as to the value of the genital ancillaries in questions of relation- 
ship it would be dispelled by the facts brought forward in the paper. 
Mr. Pierce conclusively demonstrated that generic, as well as specific 
limits, could be recognised by a study of this branch of insect 
morphology. An animated discussion followed the paper. 
Exureits.—Spring Lepidoptera were exhibited by Messrs. P. J. 
Rimmer, W. A. Tyerman, and the Rey. F. M. B. Carr. It was noted 
that melanism in Phigalia pedaria and Hybernia leucophaearia seemed 
to be more marked at Delamere and Hastham than usual. Mr. Wm. 
Mansbridge brought some curious short-winged specimens of Coeno- 
nympha pamphilus and Selenia bilunaria from Grange and Torquay 
respectively.
