SuBrFAMILY BRACHYSTOMATINZE 
Characters. — Elongate slender, nearly glabrous species of moderately large size. Head 
globose, eyes bare, with uniform facets, nearly or quite contiguous on the face; antennz located high 
up on the head, projecting horizontally, three-jointed ; proboscis very short. Thorax much shorter than 
the abdomen. Legs long and slender, sometimes differing in structure in the two sexes, the femora 
always slender, the tibize of the males sometimes apically swollen or deformed, no tibial spurs. Wings 
cuneiform and slender, costa encompassing the entire margin, the anal angle not or but little developed, 
auxiliary vein distinct, first vein ending beyond the middle of the wing, stigma normally present, third 
vein furcate or simple, the fork extending obliquely to the costa or perpendicularly to the second vein, 
basal cells very long, discal cell complete, emitting three simple posterior veins, anal cell longer 
than the basals, its crossvein continuing toward the margin, rounding or acutely closing the anal cell, 
anal vein strong, usually abruptly ending before the margin, no alula; calypteres minute.
