NOTES ON BRITISH TORTRICES. 

 BY CHAS. G. BARRETT. 

 {continued from vol. xii, page 8.) 

 Stigmonota dorsana, Fab., and orohana, Tr. 



My former notes on these species (E. M. M., x, p. 148) were 

 written from insufficient information ; for instance, Orohus niger, as 

 pointed out by Dr. F. Buchanan AVhitc, is a rare Highland A^eteh, 

 and could not be the food-plant of a species found in the North 

 of England. 



For some years past, my friends Mr. J. Sang of Darlington, and 

 the late Mr. T. Wilkinson of Scarborough, endeavoured to work out 

 the life-histories of these two species, with, until the past season, but 

 partial success. 



Orolana appears to be exceedingly local, and is found on tlie 

 cliffs to the north of Scarborough, among Vicia syJvatica, over which 

 plant it flies commonly on sunny afternoons in July. It has also 

 repeatedly been reared from larvae in the pods of that plant. 

 Mr. Sang thus describee the larva : — " When full-fed, dark yellow, 

 with a decided brown tinge ; head and second segment nearly black ; 

 spots prominent. When younger, some are lighter yellow, with the 

 spots distinct but not so prominent." Full-fed early in September, 

 when it leaves the seeds and spins a tough cocoon among rubbish. 



I reared this species myself last July from pods of Vicia 

 sylvatica received from Mr. Wilkinson.*
