Rhamphomyia is closely allied to Empis (pi. 18.) and Hilara 

 (pi. 130.), but is readily distinguished by the absence of the 

 transverse or oblique apical nervure. They feed on other in- 

 sects, and the females are generally seen sucking some fly. The 

 following appear to be two new British species. 



17. R. dispar Curt. Guide. Length If line, breadth 4 J. 



Male slender, pale ochreous, antennae and upper side 

 of head, thorax and abdomen velvety blackish ; halteres, 

 tips of thighs and extremity of tarsi fuscous ; wings beau- 

 tifully iridescent, tinged with yellowish fuscous. Female 

 ochreous, antennae and head blackish, 3 ferruginous 

 stripes on the thorax, club of halteres, tips of thighs and 

 extremity of tarsi fuscous ; wings but slightly iridescent, 

 tinged with yellow. 

 I once found these insects in abundance on flowers of the 

 Ragwort at Arrochar in Scotland, the 7th of August 1825, and 

 as I observed only males of the one and females of the other, 

 I considered them at the time to be one species, but I am not 

 certain that the male may not be the E. sciarina Fall. 



1 7% Saniculae Curt. MSS. Size of the last, and the females very 

 similar. 



Male dull ochreous : labium, antennae, head and tarsi 

 black, thorax bright ochre, club of halteres and edges of 

 abdominal segments fuscous. 

 Beginning of June in abundance in Bagley Wood near Ox- 

 ford, on the flowers of the Saniada europcsa (pi. 189.).
