154 ANNALS OF SCOTTISH NATURAL HISTORY 



RHAMPHOMYIA, sp. A single female of an undetermined species 

 captured at Dunachton. 



EMPIS BOREALIS, L. One female of this well-marked fly, Dun- 

 achton. 



P^MPIS TRIGRAMMA, Mg. One male, Dunachton. 



EMPIS LUCIDA, Ztt. Seven specimens taken at Dunachton. 



*EMPIS, sp. Several specimens of a small Empis with black legs 

 and yellow halteres were taken at Dunachton, but I am unable 

 to identify it with certainty. The remains of a small species 

 were found in the crop and gizzard of a chick from Dunachton. 



HILARA, spp. The members of this genus were common on all 

 the moors visited, but I have not been able to ascertain the 

 species. 



HEMERODROMIA MELANOCEPHALA, Hal. One of each sex taken at 

 Ballindalloch. 



ARDOPTERA GUTTATA, Hal. Three specimens of this peculiar little 

 fly were taken by sweeping at Ballindalloch. 



TACHYDROMIA, spp. Several specimens of this genus, which I can- 

 not identify, were taken at Ballindalloch and Carr Bridge. 



Family DOLICHOPODID^E. 



The members of this family are commonly found in marshy 

 ground, but I found no evidence of their having been eaten by the 

 chicks. The following list, therefore, is of interest only from a 

 faunistic point of view. 



DOLICHOPUS ATRATUS, Mg. Seven males and five females, Ballin- 

 dalloch. 



DOLICHOPUS VITRIPENNIS, Mg. A few taken at Ballindalloch and 



Burley-in-Wharfedale. 

 DOLICHOPUS PLANITARSIS, fin. Two males of this rare species, 



Dunachton. 

 DOLICHOPUS ? PUNCTICORNIS, Ztt. Two males and one female taken 



at Ballindalloch seem to fit the description of this species, but I 



cannot feel quite certain about it. 



RHAPHIUM LONGICORNE, Fin. One male, Dunachton. 



PORPHYROPS, sp. Three males of an undetermined species, with 

 yellow spine on the middle coxae, were taken at Dunachton. 

 These certainly merit further investigation. 



HYDROPHORUS BOREALIS, Lw. One male, Dunachton. 



CAMPSICNEMUS LORIPES, Hal. Two males and three females, Dun- 

 achton. 



SYMPYCNUS CIRRHIPES, Wlk. One male, Ballindalloch.
