DESCRIPTIONS OF PARASITIC HYMENOPTERA FROM CAPE COLONY. 
BY CHARLES T. BRUES. 
The species described in the present paper have recently been 
acquired by the Milwaukee Public Museum through the kindness 
of Dr. Hans Brauns of Willomore, Cape Colony. As the smaller 
parasitic Hymenoptera of this region are still practically unknown, 
it is not surprising that nearly all the species proved to be 
undescribed. 
The types are deposited in the Milwaukee Public Museum. 
FAMILY BETHYLID^E. 
MYSTROCNEMIS CAP^NSIS Sp. nOV. 
Length 7 mm. Black; thorax, antennae, tibiae and tarsi 
rufous. Head seen from above, a little longer than wide, suddenly 
narrowed just before the eyes, and rounded-truncate on the 
anterior margin, overhanging the insertion of the antennae. 
Antennae 27- jointed, setaceous ; scape stout, two times as long as 
broad, following joints all of about equal length, gradually nar- 
rowing, the last a trifle longer. First few flagellar joints nearly 
twice as wide as long. Eyes hairy. Pronotum about two and 
one-half times as long as wide, arcuatelv incised posteriorly ; with 
a median impressed line. Mesonotum very small, subtriangular, 
the scutellum about twice as large, rounded and convex ; meta- 
notum nearly as long as the prontum, and considerably wider, 
obtusely pointed behind. Abdomen composed of five segments of 
nearly equal length, the sides subparallel ; tip pointed. Legs 
stout. Anterior femora a little more than two times as long as 
wide, ovate in shape; the anterior tibiae shaped like the femora, 
but only two-fifths as long. Anterior tarsi stout, the tarsal claws 
stout and strong, bidentate at tip. Claws of four posterior tarsi 
very slender, with a rather obtuse tooth beneath near the tip. 
Entire body sub-shining, covered with a short whitish pubescence. 
Described from one female from Sunday River, Capland 
(O'Neil). This is the third species of this recently discovered 
genus to be described. 
The type species was described by KiefTer in 1905 from 
103
