Drapetis aterrima Curt. — M. : Westport, twelve specimens in Demesne and 

 one in garden ; Lough near "Westport, one specimen (G.). According to 

 Lundbeck (" Diptera Danica," Part iii, p. 255) this is the same as nervosa 

 Lw. and nigritella Ztt. 

 Tachista arrogans L. — M. : Westport, one 9 in Demesne (H.). 

 **Tachydromia albocapillata Fln.—M. : Westport, four $ and eight 9 in 

 Demesne, and Knappagh, one <J (G.). This species is new to the British 

 fauna. It is closely allied to T. albiseta Pz., but distinguished therefrom 

 by several important characters. The third joint of the antenna is longer, 

 the whole antenna (without the arista) being about as long as the head, 

 while the arista is only about as long as the third joint. The legs are 

 entirely black, except for some obscure brownish about the knees, 

 while the wings have the cubital vein more curved. 

 *T. calceata Mg.—M.. : Belclare, one $ (H.) ; Knappagh, one 9 (G.). 

 T. cothurnata Mcq. — M. : Westport, one $ and two 5 hi garden (G.). 

 T. flavipes Fab. — M. : Belclare, one $ (H.) ; Westport, one 9 in Demesne 



(G.). 

 *T. fulvipes Mg. — Gl. : one 9 (G). M. : Roonah, one 9 (? collector) ; Mulranny, 

 two $ and eight 9 (G.) ; Westport, one 9 in Demesne (G.). This 

 species varies much in the colour of the legs. Most of the specimens 

 from Mulranny have the legs entirely yellow, while the Westport example 

 shows the other extreme. But I have little doubt of their representing 

 the same species. 

 T. longicornis Mg. — M. : Westport, one pale (immature) 9 in Demesne (G). 

 T. minuta Mg.— CI. : one 2 (G.). 

 *T. pallidiventris Mg. — CI. : one $ and two $ (G). M. : Mulranny one $ ; 

 Westport, two $ in Demesne ; Castlebar Lough, one $ and 9 ; and 

 Knappagh, one $ (G.). 



Family Dolichopodidae. 



Sciapus (Psilopus) platypterus Fab. — CI. : one 9 (G.). M. : Westport, one 



(J in Demense (? collector) ; Belclare, one £ (H.) and one 9 (G.) ; 



Brackloon Wood, one 9 (G.). 

 Eutarsus aulicus Mg. — M. : Westport, one 9 on riverside (G.). 

 *Dolichopus arbustorum Stann. — M. : Belclare, one 9 (H.). 

 D. atratus Mg. — CI. : two £ (H.) ; two $ (no data) ; four $ and four 9 



(G.). M. : Achill, one S (no data) ; Louisburgh, six $ and two 9 



(M,); one 9 (H.). 

 D. atripes Mg.— CI. : (G.). M. : Louisburgh (M. and H.) ; Mulranny, 



Belclare, Knappagh, and Lough near Westport ( G.).
