1 . Second longitudinal vein (R 2+ 3 ) long, reaching the costa 
much beyond the tip of the first longitudinal ( R 1 ) and 
apicad of the anterior cross-vein; the last section of 
the costa at most three times the length of the penulti- 
mate section. Base of third longitudinal vein (# 4 + 5 ) 
bare. One pair of vertical bristles. Two pad-like 
pulvilli at the sides of the bristle-like empodium, one 
much larger than the other 2 
Second longitudinal vein short, reaching the costa to- 
gether with or close to the tip of the first longitudinal ; 
the last section of the costa equal to at least five times 
the distance between the tip of the first and that of 
the second longitudinal veins 3 
2. Apical lobes of the fronto-clypeus regularly and sharply 
triangular, their inner margins nearly straight. Scu- 
tellum as a rule wholly ivory-white ; wing veins mostly 
pale testaceous, with some darker stretches. Smaller, 
the wing 5 to 6 mm. long H. capensis 
Apical lobes of the fronto-clypeus irregularly and 
broadly triangular, their inner margins curved. Scu- 
tellum fuscous to ferruginous on the sides, yellowish 
white in center, rarely more extensively yellowish; 
wing veins as a rule rufous to dark brown. Larger, 
the wing 6 to 8.5 mm. long H. equina 
3. Base of third longitudinal vein setulose over some length 
on the upper side. One pair of vertical bristles. Only 
one pulvillus well developed, the other rudimentary 4 
Base of third longitudinal vein bare 6 
4. Second longitudinal vein very short, forming an oblique 
cross-vein which ends in the first longitudinal and runs 
from opposite or apicad of the upper tip of the ante- 
rior basal cross-vein to basad of the anterior cross- 
vein. Scutellum as a rule with three ivory-white spots, 
the largest in the center; bristles of head and thorax 
pale. Large, the wing 7 to 8 mm. long H. maculata 
Second longitudinal vein much longer and more oblique, 
ending in the costa close to or at the tip of the first 
longitudinal and running from basad of the upper tip 
of the anterior basal cross-vein to opposite or basad of 
the anterior cross-vein 5
