ON THE DIPTERA OF ST. KILDA 153 



32. EMPIS STERCOREA, Linn. i 9 . 



33. EMPIS sp. i $ and 2 $ 9 of a small shining black species 



with simply ciliated dark legs. 



34. HILARA sp. 15 $ $ and 9 9 9 of a species belonging to 



the chorica group, but I cannot determine it with certainty. 



35. CLINOCERA FONTINALIS, Hal. 2 <J $ and 5 99. [On 



surface of water in the " Well of Virtues," West Bay. J. W.] 



36. HEMERODROMIA PRECATORIA, Fin. 4 $ $ and 14 $ 9. 



37. TACHYPEZA NERVOSA, Mg. i 9 and 2 < o Although not 



recorded as British I can come to no other conclusion than 

 that the St. Kilda specimens represent the true nervosa of 

 Meigen. I have also seen specimens of the same species from 

 Aberfoyle taken by Mr. A. E. J. Carter. 



38. TACHYDROMIA COMPTA, Wlk. 4 9 9 . 



39. TACHYDROMIA sp. i $ and 599 like cursitans. Fab., but 



the abdomen has no grey side-spots. 



Family DOLICHOPODID^E. 



40. DOLICHOPUS ATRATUS, Mg. 1 6 $ $ and 1 5 9 9- [Abundant 



everywhere, especially in marsh. J. W.] 



41. DOLICHOPUS PLUMIPES, Scop. 41 3 and 24 9 9. [Abun- 



dant everywhere, especially in marsh. J. W.] 



42. DOLICHOPUS GRISEIPENNIS, Sfann. 16 $ and 129 9. 



[Abundant, but chiefly in marsh. Later in appearance than 

 the other two species of the genus. J. W.] 



43. SYNTORMON PALLIPES, Fab. 2 o 6 an d 299. 



44. CAMPSICNEMUS sp. i $. 



45. SYMPYCNUS ANNULIPES, Mg. 14 $ $ and 15 $ 9. 



46. ? SCHOENOPHILUS sp. Two specimens of a tiny species which 



appears to belong to this genus, but it is not versutus, Wlk. 



47. Represented by five specimens which I am unable to de- 



termine. 



Family LONCHOPTERID^. 



48. LONCHOPTERA TRILINEATA, Zett. 6 $ $ and io $ 9. These 



agree fairly well with Zetterstedt's description, and I cannot 

 make them fit with any other species, in spite of the fact that 

 trilineata is not on the British list.
