DIPTERA 
and high, the anterior margin produced into a triangle which descends to the base of the antennae; eyes 
round; ocelli three in number, the laterals large, contiguous to the eye margin, the middle one small, 
imbedded in a groove at the base of the frontal triangle; palpi incurved, four jointed, the first joint 
small, the fourth longerthan the second and third taken together; antenna slender, arcuate, 2^-14 jointed 
the two basal joints differentiated, both with setae at the apex, flagellar joints cylindrical, compressed, 
pubescent. Thorax small, oval, highly arched; mesonotum hairy, lateral margins without conspicuous 
setae; scutellum semicircular, with sets at the margin, metanotum high, steep, somewhat arched. 
Abdomen of the male six segmented, narrowed at the base, compressed, with rather large apical segment 
and forceps (PI. 7, Fig. I 0); that of the female with seven segments, constricted at the base, usually 
compressed, often cylindrical, with a short, stout ovipositor, ending in a pair of small lamellae. Legs 
moderately long; middle and hind femora more compressed than the fore pair; tibiae with spurs and 
lateral setje; hind tibiae and tarsi subequal in length or the latter shorter. Wings large, extending beyond 
the abdomen, with rounded base, microscopic setulose. Costa scarcely noticeably produced beyond the 
tip of the radial sector, ending before the tip of the wing; subcosta long, ending in Rj beyond the middle 
of the basal cell R; the fork of the media under or proximad of the base of the radial sector; fork of the 
cubitus proximad of the base of the fork of the media; anal veins delicate, incomplete (PI, 6, Fig. 10). 
These flies are found in deep woods and shrubbery. Distinguished from Syntemna by the position 
of the ocelli.
