ON THE DIPTERA OF ST. KILDA 157 



Family DROSOPHILID^E. 



1 01. SCAPTOMYZA GRAMiNUM, Fin. 4 specimens. 



102. DROSOPHILA sp. i specimen. 



Family OPOMYZID^E. 



103. BALIOPTERA COMBINATA, Linn. i 9 



Family CHLOROPID^. 



104. OSCINIS PUSILLA, Mg. 4 specimens. 



105. CENTOR CERERIS, Fin. i specimen. 



1 06. CHLOROPS sp. 3 specimens. 



Family AGROMYZID^E. 



107. SCHCENOMYZA LiTORELLA, Fin. 9 $ $ and 27 $ . Some 



of the $ 9 show three shining black fasciae on the abdomen 

 where the posterior edge of a segment slides under the 

 anterior edge of the succeeding one. The question has 

 occurred to me whether Meigen's fasdata is not founded 

 on specimens in this condition. So far as I can see there is 

 no other difference between the two species. 



1 08. CERATOMYZA DENTICORNIS, Panz. 13 specimens. 



109. AGROMYZA NIGRIPES, Mg. i specimen. 



i lo-n 2. PHYTOMYZA spp. 6 specimens representing at least 3 

 species. 



Family BORBORID^E. 



113. BORBORUS NITIDUS, Mg. i c? and i $. 



114. BORBORUS GENICULATUS, Mcq. i $, . 



115. BORBORUS ? VITRIPENNIS, Mg. i 9- 



1 1 6. LIMOSINA SYLVATICA, Mg. 4 $ $ and 599- 



117. LIMOSINA FONTINALIS, Fin. 3 specimens. 



1 1 8. LIMOSINA CRASSIMANA, Hal. 3 specimens. 



119. LIMOSINA sp. i specimen. 



NOTE. 



Since the above paper was in type I have received some notes 

 from Mr. Waterston regarding the capture of certain of the Diptera, 

 also in reference to the weather conditions, methods of collecting, 

 and other information of some interest. His remarks are incor- 

 porated in the following paragraph.
