in dry places" ; this may perhaps be a hibernating resort for such few 

 specimens as may survive the winter, but I do not think such an event 

 is at all common. Morley swept a specimen fi'om Mullein, and this may 

 have been merely a fortuitous occurrence ; but it must be remembered 

 that the broad leaves of Vcrhascum, and especially the dead ones, are 

 well known to shelter other species of Tinf/idae. 



D. sti'ichnocera is distributed throughout Central and Southern 

 Europe. In Britain it is more widely spread than D. fricornis, and 

 has been recorded from all the coast counties from Norfolk to Cornwall 

 inclusive, as well as from Cumberland, Yoi-ks, iSTotts, Leicester, War- 

 wick, Hereford, Gloucester, Monmouth, Oxon, Bucks, Herts, Middlesex, 

 Surrey, Berks, and Wilts — 24 English counties in all. The only Welsh 

 records are from Carmarthen and (llamorgan, and it occurs in Scotland, 

 but is not recorded from Ii-eland.

TWO ADDITIONS TO THE LIST OF BRITISH TACHINTDAE (DIPTERA) 

 BY MA.TOR E. E. AUSTEN, D.S.O. 



Since the publication of the late Mr. Gr. H. Verrall's " List of 

 British Diptera " in 1901, the exertions of Mr. C. J. Wainwright and 

 others have contributed a number of additions to the names of the 

 Tachinidae therein recorded, but, so far as the present writer has been 

 able to discover, the occurrence in Great Britain of the two species 

 mentioned below has hitherto escaped notice. 



BiUaea irrorata Mg. — In the case of this fly, which is of interest 

 in being one of the small minority of TacTiinidae that are parasitic upon 

 Coleoptera, the host is Sajyerda popnlnea L., a common and widely 

 disti'ibuted Longicorn, tlie larvae of which attack the smaller branches 

 of the poplar, aspen, and other trees. The first specimen of 5. irrorata 

 to be recognized in this coiintry was a female, bred at Kew, in April 

 1921, from material obtained at Bagshot, by Dr. J. W. Munro, and 

 subsequently presented by him to the Britisli Museum (Natural 

 History) ; while in June of the present year a series of examples of 

 the species was similarly obtained at Abbey Wood, Kent, by Mr. St. 

 .Tohn Marriott, who has generously added two females to the National 

 Collection. An interesting point in connection with the life-history of 

 B. irrorata is that pupation takes place inside the branch attacked by 

 the larva of S. populnea, in the tunnel left by the latter. This is well
