restricted to decayed hawthorn alone, as we found some 

 specimens on maple leaves. It seems likely that entomo- 

 logists may find it worth while to examine decaying boughs 

 in. showery weather, or to place such boughs in suitable 

 positions with a view to attract moths.

Colias Edusa, var. Helice, on Cliftok Down. 



It may be of interest to record that a fine specimen of 

 Colias Edusa, var. Helice, was captured on Clifton Down by 

 Mr. G. C. Thompson on September 29th, 1894. In Mr. A. 

 E. Hudd's list of the Lepidoptera of the Bristol District, the 

 first instalment of which appeared in the Proceedings of 

 this Society in 1877, this variety is stated not to have 

 occurred in Gloucestershire, and I am not aware that any 

 capture has since been recorded until the one above 

 mentioned.

Abstract of Paper on the Genus Coronis. 



The genus Coronis belongs to the Uraniidce, which have 

 been placed by various authors, by turns, in nearly all the 

 divisions of the order Lepidoptera, but are now generally 

 considered to belong to the Bomhycidce, to which group 

 Westwood referred them in his monograph published in 

 Trans. Zoo. Society for 1878. 



The range of Coronis is from Brazil to Central America 

 and Mexico, and one species extends into the West Indies. 

 The number of species is about twenty-five. 



The larva is bombycid in many of its characters, and the 

 pupa is enclosed in a loose cocoon spun at the base of a 

 folded leaf. 



Attention was called to the divergence in coloration of
