Gen. I.— LEPTOPA, Ztt. 



Cordi/lura, Flu., Hal. 

 Gen. ch. — Head sub-globose, eyes long and widely separated ; 

 antennae short, with bare arista; oral setae several in number, placed 

 in a small excavation on each side of the mouth ; abdomen very short, 

 with only four segments. 



Sp. 1. — L. FILIFOEMIS, Ztt.

This little fly is quite anomalous, and differs essentially from all others in this 

 family ; it might almost as well be placed among the Coenoslnce, on account of its 

 lengthened eyes and short abdomen ; but the small calyptra and other characters 

 refer it to the Acalypterati. It is quite yellow, with the exception of a subdistinct 

 dark dorsal abdominal stripe, and a brown tinge upon the tarsi. Length, 3 mm. 



This rare species was found in Ireland by the late Mr. Haliday.

 short, with the third joint oblong ; arista plumose ; palpi cylindrical, 

 with ends undilated and furnished with one or two minute apical setae ; 

 proboscis rather thick ; thorax convex ; scutellum with either two or 

 four long bristles ; abdomen long, narrow, and sub-cylindrical in the 

 male, with the apex incurved, lanceolate and pointed in the female ;
