Notes on Phoridce From South Africa

ovate, as long as thick and less than half as long as the eye-height ; 
arista apical, faintly pectinate, as long as the front coxa. Meso- 
notum with one pair of very widely separated dorsocentral 
bristles and four scutellar bristles of which the median (not 
lateral) pair is often much smaller. Abdomen clothed with 
minute, almost imperceptible bristly hairs, more distinct on the 
apical segment, and enlarged to form a very evident apical row 
along the posterior margin of the other segments ; venter entirely 
membranous, without hairs or bristles. Central portion of 
hypopygium pyriform, with a slender, upturned stylet projecting 
from its tip; dorsal lamella attached at the middle of the middle 
lobe, with parallel sides, supplied with long sparse bristles; left 
side with a large plowshaped lamella; ventral middle-piece with 
a large upturned hook which is spinose inwardly near apex; 
right side above with a small triangular plate, the apex of which 
is drawn out into a small finger-shaped piece that bears two 
long bristles at its tip. Legs rather stout; anterior tibia with- 
out spur; others each with a single one; no very distinct tibial 
setulse; hind metatarsus with six transverse bands of bristles. 
Wings with the costa extending distinctly beyond the middle, 
its bristles close-set, minute, scarcely longer than the diameter of 
the costal vein; first and second sections of costa equal; medias- 
tinal vein distinct; fourth vein almost straight; fifth curved at base ; 
sixth faintly bisinuate; seventh clearly indicated, close to the 
anal angle. Halteres very large, with pale stalk and dark-colored 
knob. 
There are numerous specimens of both sexes bred from 
larvae in a rotting stem of paw-paw {Carica papaya) at East 
London, Cape Province, February 2, 1922. 
From the descriptions above it will be evident that the 
bristling of the front is different in the sexes, as the female has 
only one bristle lateral to and just above the post-antennal group 
of four. I have carefully examined a large number of the minute 
females and am certain that none of them show more than one 
bristle in this position.
