1951 3 Hungerford — African Hydrometra 69 
from “Uganda, Kampala, G. L. R. Hancock” is not quite 
the same. 
Hydrometra ugandae Jaczewski 
This species was described from Uganda: Bugomolo. 
The large brush of semi-erect brown hairs on the basal 
portion of the seventh abdominal tergite of the female and 
the short somewhat downward curving terminal spine 
makes the female readily distinguishable. I have examined 
the female paratype. Dr. China made a drawing of the 
male type in the British Museum and this drawing shows 
spiny tufts present on the last abdominal segment although 
Dr. Jaczewski’s description says they are not present. 
Hydrometra goodi n. sp. 
Size and Color: Length 12.15 mm. ( S ) - 12.96 mm. ( $ ), 
General color brown, the abdominal tergites, except the last 
one, shining, nearly black and contrasting with the much 
lighter connexivum. The pronotum with a narrow longitudi- 
nal median frosted line bordered successively on each side 
by a purplish-brown band, a brown band, another purplish 
band, outside of which is a curved frosted line above the 
anterior acetabula and another bordering the margin of the 
posterior lobe and continuing to the posterior acetabula. 
Under side of body somewhat frosted. Above, the connexi- 
vum has a small frosted spot at the segmental junctions. 
The last abdominal segment and genital segment covered 
with short hairs in both sexes. 
Structural characteristics: 
Head: Length 140 units; the ratio of the anteocular 
part of the head to the postocular part is given by the 
formula AO : PO : : 88 : 41. The dorsal interocular groove 
less than the diameter of the eye, the ventral interocular 
groove also short. The clypeus is quadrate, truncate in 
front, its median length slightly more than half its width, 
the rostrum surpassing two thirds of the postocular dis-
