Characters. — Head round, flattened in front, placed low upon tbe tborax; front broad, tbe 
anterior margin produced in a triangle, tbe apex of whicb reaches to the base of tbe antennae; eyes 
round; ocelli three in number, tbe Literals large, contiguous to tbe eye margin, the middle one small, 
placed in a groove near tbe base of tbe frontal triangle; palpi incurved, four jointed, the first joint 
small, tbe fourtb about as long as tbe second and third taken together; antennfe in tbe male frequently, 
in the female usually nearly cylindrical, slender, arcuate, 2 -j- 14 jointed, the two basal joints differenti- 
ated, the second with set;E at the apex, flagellar joints cylindrical, slightly compressed, pubescent. 
Thorax oval, highly arched, mesonotum hairy, tbe hairs on the sides longer, no setae; scutellum nearl}' 
semicircular, margin setose, metanotum high, somewhat arched. Abdomen of the male slender, six 
segmented, compressed, constricted at the base, with rather large apical segment and forceps (PI. 7, 
Fig. I 2); female with seven segmented abdomen, cyHndrical, constricted at the base, with ovipositor 
ending in two lamellae. Legs slender, fore tibite shorter than the corresponding tarsi, all tibia; with spurs 
and lateral setae. Wings oval, with a more or less rounded base, somewhat longer than the abdomen, 
microscopic setulose. Costa produced, sometimes only very slightly, beyond the tip of the radial sector 
and ending at a greater or less distance from the tip of tbe wing; subcosta short, usually ending free, 
rarely ending in tbe costa; media forks distad of the base of tbe radial sector, rarely directly under it; 
cubitus folks distad of the fork of tbe media, its branches usually widely divergent; anal veins incom- 
plete, almost rudimentary (PI. 6, Fig. I I ). 
The forking of tbe media distad of tlie base of the radial sector, and the produced costa will 
distinguish this genus from Exechia. Tbe flies are found in woods and among shrubber}' usually in 
Spring and Fall.
