DIPTERA NEW TO THE SCOTTISH LIST 261 



DIPTERA NEW TO THE SCOTTISH LIST. 



By A. E. J. Carter. 



All the insects here mentioned appear to be unrecorded 

 from Scotland. Some of them are fairly common and widely 

 distributed, and their absence from our List is, of course, due 

 to the small number of entomologists who collect or study 

 the Diptera. I have to thank Mr James E. Collin for kind 

 help. All my specimens of Empidae have been examined 

 by him ; some are undescribed species, but I have not 

 included any of them here, r Species captured by the Rev. 

 James VVaterston are in all cases marked by his initials : 

 all the other records are from my own captures. 



1. Rhamphomyia tibiella, Zett. — Both sexes taken at Blairgowrie in 



June 1911-13. The ? of a pair taken in coihi, 12th June 

 19 13, had the (^ of a small yellow Ta?iypus sp. as prey. 

 Mentioned by Lundbeck {Diptera Danica, iii., 1910) as 

 occurring in England, but not yet recorded in any of our 

 journals.
