TORTRIX PRONUBANA, Hb. : A SPECIES NEW TO THE BRITISH 

 LIST, IN SUSSEX. 



BY W. H. B. FLETCHER, M.A., F.E.S. 



About 10 :i m. on Monday, October 23rd, one of the frosty 

 but bright sunny iiiorningB which have distinguished the latter part 

 of the present month, I flushed in my garden a small moth, the 

 bright colouring of which suggested as it flew that it might be Py- 

 rausta purpuralis. Wondering what that species could be doing on the 

 wing at such a time of the year, I followed it up. After two short 

 flights it pitched on a twig of Coronilla glaucn, from which I boxed it. 

 On examination it has proved to be a specimen of Tortrix pronubana 

 Hb., a male in fine condition, evidently fresh from the pupa. 



1 have to thank my friend Mr. E. E. Bankes for his kind assis- 

 tance in identifying it.

A DIPTEROUS ENEMY OF ENGLISH HOTHOUSE GRAPES. 

 BY EKNEST E. AUSTEN. 



I have recently hud submitted to me for identification by Mr. G. S. 

 Saunders, of Wandsworth Common, some small Diptera, accomjjanied 

 by the statement that the larvae from which the flies were bred were 

 "injuring a crop of grapes grown under cover at Thongsbridge, near 

 Huddersfield." The sender added that '' Lady Downe's Seedling " was 

 the only variety attacked, and that there were several larvae in each 

 grape. Comparison with specimens already in the Museum collec- 

 tion soon showed that the insects belong to the species well known 

 on the Continent and in the United States under the name Droso- 

 phila ampelophila, Lw , which was originally described from Cuba. 

 Further study, however, led to the interesting discovery that (at least 

 so far as can be judged from the descriptions of Meigen, Schiner, and 

 Loew) D. ampelophila, Lw., is undoubtedly identical with D. melano- 

 gaster, Mg., a species recognised as British in the first edition of 

 Mr. Verrall's "List of British Diptera " (1888). This synonymy 

 is new. 



In length Drosophila melanogasfer measures from 1^ to 2^ mm.; 

 the colour of the head, thorax, and base of the abdomen is ochraceous ;
