for one row of short hairs along the outer margin of the coxe and 
a few appressed ones on the sides of the metasternum and on the 
somewhat broad episterna; hind femora broad, hind tarsi short, also 
broad, and with only three long, stiff, single bristles underneath. 
Length 7 mm. ; width 44 mm. 
Hab. Southern Rhodesia (Victoria Falls). 
This species very closely resembles examples of <Awtoserica 
annectens, but it is easily distinguished owing to the tri-dentate 
tibiz and other specific characters. 
DIAPHOROSERICA, n. gen. 
Plate XLVI., fig. 3. 
Very closely allied to Gryphonycha, the chief distinctive characters 
being the shape of the fore tarsi and claws of the male; the former 
are short, the second, third, and fourth joints are triangularly dilated, 
the fifth is much broader and longer, the claws are conspicuously 
diverging, each one is deeply cleft, the upper tooth of the left one 
being very slender, and the lower very broadly lobate, this lobe is 
conspicuously wider in the outer than in the inner claw; in the 
female the claws are deeply cleft, the lower tooth is, however, wider 
than the upper; antenne 9-jointed in both sexes, the 3-jointed club 
is nearly as long as the pedicel in the male. The prothorax curves 
very strongly forwards, and the mentum is not as densely hairy 
as in Gryphonycha. This genus differs from Newroserica, Brensk., 
in both the anterior claws of the male being toothed and not 
widened, lobe-like, and in the club not being strongly elongated. 
DIAPHOROSERICA MASHONA, Nl. Spec. 
Rufescent, with a fleshy tinge and a more or less strong opaline 
sheen; antennz testaceous; clypeus with a plain frontal suture, 
arcuately emarginate in front but with the margin reflexed and 
slightly aculeate in the centre, the outer angles are distinct, but 
not prominent, the surface is deeply punctured, the head less 
so; prothorax slightly narrowed laterally in front, sinuate behind 
and also along the base, sloping forwards, vaguely punctulate only 
along the base and sides; scutellum long, aciculate; elytra elongated, 
plainly striato-punctate with the intervals sub-tectiform, the punc- 
tures of the strive impinge on each side of the sub-tectiform intervals; 
anterior tibiz bi-dentate. 
Length 6-7 mm.; width 31-4 mm. 
Hab. Southern Rhodesia (Sebakwe).
