*Limnophora litorea Fin. — CI.: one $ (G.). M. : Achill, one $ (? collector). 



**L. nigriventris Ztt. — M. : Mulranny, four $ and five 2 , and Westport, four 



9 in Demesne (G.). This is, I believe, a new record for Britain. It is 



recognized in the ? sex by the highly-polished area on the frons. 



*Hydrophoria ambigua Fin. — M. : Belclare, one $ (H.) ; Castlebar Lough, one 



$, and Brackloon Wood, four ? (G.). 

 *H. brunneifrons Ztt.— M. : Clogher, one 2 (G.). 

 *H. ruralis My. — M. : Brackloon Wood, two <J (G.). This is the H. anthomyiea 



Bond, of Meade's papers and Verrall's List. 

 *Hylemyia brunneilinea Ztt. (seticrura, Bond.). — CI. : one 9 (? collector) ; one 

 £ and one 2 (G.). M. : Westport, three $ and two 2 in Demesne, 

 Lough near Westport, one <J and four 2 , and Clogher, one 2 (G.). The 

 colour of the frontal stripe in the 2 is not constant in this species, being 

 in some specimens entirely black, and in others black tinged with red in 

 front. Meade says : " frontal stripe wide and rufous," but this is not 

 accurate. 

 *H. puella Schin. (nee Mg.). — M. : Brackloon Wood, three £ and one 2 (G). 

 This is a rare and little-known species. It is distinguished by its pale 

 legs, long-haired arista, and two-striped thorax. 

 *H. pullula Ztt. — M. : Knappagh, one $ (G.). 



H. strigosa Fab. — M. : Westport, one 2 in Demesne (? collector), three $ and 

 three 2 in Demesne and two 2 on riverside (G.) ; Belclare, three <$ , 

 Knappagh, one 2 > and Brackloon Wood, twenty-two <J and two 

 2 (G.). 

 *H. tristriata Stein (? cinerclla Meade). — M. : Brackloon Wood, one $ (G). 

 *H. variata Fin. — CI. : one 2 (Milne); two $ and one 2 (G.). M. : Westport 

 Demesne, one 2 (H.), one $ and one 2 (G.) ; Lough near Westport, 

 two 2 (G.). 

 Pegomyia bicolor Wied. — CI. : one £ (G.). M. : Westport, one 2 on river- 

 side and one $ in garden, and Clogher, three $ (G.). 

 *P. flavipes Fin. var. diluta, Stein. — M. : Belclare, one <? (H.). 

 *P. rufipes, Fin. — M. : Belclare, one £ (H.); Brackloon Wood, one 2 (G.). 

 Chortophila (Phorbia) cilicrura Bond. — CI. : two £ (G.). M. : Mulranny, 

 two 2 > and Knappagh, one <$ (G.). [See remarks under C. tricho- 

 dactyld], 

 C. discreta My. — CI.: one £ (G.). M. : Mulranny, one $, Westport, one 



(Jon riverside, Lough near Westport, one <$ , and Clogher, one $ (G.). 

 C. trichodactyla Eo'nd. — CI.: one £ and four 2 (G.). M. : Mulranny, four 

 <J and one 2 ; Westport, two $ and two 2 in garden, and Knappagh, 

 one <J (G.). The 2 of this species may be distinguished from that of
