DIPTERA 
arcuate, 2-|-i4 jointed, the basal joints differentiated, setose at the apex, the flagellar joints cylindrical, 
somewhat compressed, pubescent. Thorax small, oval, highly arched, anterior slightly produced beyond 
the head; mesonotum pubescent, lateral margins with longer hairs; scutellum semicircular, with setag 
on the margin; metanotum high, steep, somewhat arched. Abdomen of the male six segmented, with 
small anal segment and small forceps; in the female with seven segments, the ovipositor short, and 
ending in two oval lamellae. Hind legs moderately long, the fore and middle pairs rather short, coxas long, 
the hind pair very broad, the tibiae strong, somewhat clavate, spurred, the fore and middle pairs usually 
without lateral set^, the hind pair with two ranges of stout setae, the middle pair with two setae on the 
inner side, plantie of the hind tarsi ciliate with fine setulae. Wings longer than the abdomen, oval, with 
rounded base; with longitudinal rows of microscopic setulse. Costa does not reach the tip of the wing and 
is not produced beyond the tip of the radial sector; subcosta very short, curved towards the costa but not 
reaching it ; media forks distad of the base of the radial sector, its petiole short ; cubitus simple ; anal 
veins incomplete, the second one stout (PI. 6, Fig. 27). These flies may be found in the woods and 
among shrubbery. The larvae live in rotten wood and in fungi.
