NEMOURA DUBITANS (Morton) as a British Species. 



By Lieut. -Colonel C. G. Nurse. 



Although I devote myself, in my entomological studies, 

 chiefly to Lepidoptera and Hymenoptera, I have been for some 

 years in the habit of taking such specimens of Neuroptera as I 

 may come across casually. Last year I sent a number of speci- 

 mens of the latter order to Mr. K. J. Morton for determination, 

 and among them he found a single example of Nemoura dubitans, 

 which species had not previously been recorded from Britain.
