DIPTERA FEOM THE NEIGHBOUEHOOD OF MAELBOEOUGH, 

 INCLUDING ONE SPECIES NEW TO BEITAIN. 



BY T. W. KIRKPATRICK. 



The following is a list of some of the less common Diptera which 

 I have taken this year within a radius of ten miles from Marlborough, 

 Wilts. In addition to these I am able to record a species taken 

 several years ago, which is new to the British list. 



Trichocera hirtipennis, Siebke : I have not taken this myself, but an example 

 was captured by Mr. E. Meyrick on July 3rd, 1902, at Marlborough, which 

 Mr. Collin kindly identified as this species. It is an interesting addition to the 

 list of British Diptera. 



Odontomyia argentata, Fab. : 1 $ on Ranunculus blossoms in marshy ground 

 at Chilton Foliat, 14.5.14. 



Stratiomys potamida, Meig. : 1 ? , 4.7.14; 2 <J, 1 ?, 14.7.14. on the flowers 

 of large Umbelliferge (Heracleum) near the Eiver Kennet, at Marlborough. 



Leptogaster guttiventris, Zett. : 1 ? among low herbage, 23.6.14. at 

 Marlborough. 



Dioctria celandica, L. : common in the West Woods in June and early 

 July. Its prey seemed to consist, in all the cases I observed, of Pipunculus 

 campestris, Latr. 



Isopogon brevirostris, Meig. : Abundant from July 4th to 20th in one very 

 limited locality at the edge of a cornfield, near Marlborough. 



Anthrax cingulatus, Meig. : 1 $ on Umbelliferse in a hedge at the foot of 

 chalk downs, Marlborough, 20.7.14. 



Neurigona suturalis, Fin. : 2 $ <j> , taken on Rhamnus, 4. 7. 14. near 

 Marlborough. 



Dolichopus planitarsis, Fin. : This species was common on alder leaves at 

 Chilton Foliat on May 14th. It is generally considered somewhat rare, but is 

 probably only overlooked, as it only occurs in early spring, and a week later 

 had entirely disappeared. 



B. longitarsis, Stan. : A pair in the same locality as the last, July 11th. 



Campsicnemus curvipes, Fin. : I took an example on the window of an out- 

 house in Marlborough on February 2nd this year. A curious place and date. 



Orthoneura brevicornis, Lw. : 1 $ , May 14th, on Ranunculus at Chilton 

 Foliat. 



0. nobilis, Fin. : 1 $ on Umbelliferse at the edge of West Woods, July 2nd.* 

 This locality is not near any such marshy ground as is usually frequented by 

 species of Orthoneura and Chry so g aster. 



Chilosia vulpina, Meig. : 1 $ , 26.5.14: In Henswood, near Marlborough, and 

 two other males on July 7th and 8th.
