PJusia moneta in East Yorkshire. — From the report of a 

 meeting of the Hull Scientific, etc., Club, we notice Mr. R. 

 Chapman exhibited a specimen of a moth taken at Hull on 

 June 27th, and identified as the new ' Plusia moneta.' ' As this 

 is a species that is not only comparatively new to British 

 Lepidoptera, but has never been previously taken in Yorkshire, 

 it evoked a good deal of interest.' — Ed. 



Plusia moneta is not quite new to Yorkshire, as a specimen 

 was taken at Robin Hood's Bay, by Mrs. Holmes of Sevenoaks, 

 so long ago as 1901. The first record for the species in Britain 

 was in 1890, when one was captured at Dover. There was 

 probably a small immigration at that time, and the moth 

 evidently found our climate most congenial to it, and has 

 since spread with wonderful rapidity, and is now quite common 

 in our Eastern Counties, and will apparently soon become so 

 in the Midland ; and at no distant date, probably throughout 

 England. It is essentially a garden insect, the larvae feeding 

 on Monkshood and Delphinium. Being a beautiful and con- 

 spicuous moth, it is too a welcome addition to our gardens.— 

 Geo. T. Porritt.
