CAMERON—H YMENOPTERA. 83 
This is a smaller species than the type of the genus, I. natalensis, Kriech., from 
Natal; that species has the terebra 7 mm. long. 
27. Braunsia melanoptera, sp. nov. 
Ferruginous, the apical segments of the abdomen more or less, the hind tibixe (except 
at the base) and the hind tarsi, black, as are also the antennze and the sheaths of the 
ovipositor ; wings dark fuscous, a hyaline cloud between the radius and transverse basal 
nervure, extending right across the wing, the stigma and nervures black. °. 
Length 8-10 mm., ovipositor as long as the body. 
Localities. Seychelles, Coetivy. 
Antenne longer than the body, densely covered with stiff black pubescence. Malar 
space yellowish, two-thirds of the length of the eyes. Mesonotum distinctly trilobate 
the middle lobe stoutly keeled down the apical half, the keel prolonged into the apical 
depression. Apex of scutellum with a narrow keel, broadly rounded laterally and with a 
slight incision in the middle; the basal lateral keels roundly curved. In the centre of 
metanotum, on the apical slope, are two stout parallel keels, forming an area twice longer 
than wide; the sides are closely, irregularly, somewhat obliquely striated. There is a 
curved keel near the bottom of the propleurze; a depression, straight above, rounded 
below, under the middle of the mesopleuree. First abdominal segment about two and a 
half times longer than it is wide at the apex, which is twice wider than the base; the 
latter is smooth, bare, and shining to beyond the middle; the base and apex depressed, 
the centre roundly raised; the sides stoutly keeled; the apex is striated, the striz stout, 
more or less twisted; the middle segments closely, regularly, longitudinally striated, 
the apical three smooth ; the suturiform articulation wide, curved, crenulated, Hind tibize 
and tarsi densely haired. Areolet almost triangular, the nervures almost touching, the 
apical rounded. 
_. Most of the known species of Brauwnsia are African, but many are found in Malaya, 
and one is European. 
RHOGADIN &. 
28. Camptocentrus annulipes, sp. nov. 
Black, the base of the tibize broadly clear white; the base of metatarsus paler than 
the rest. Wings hyaline, the stigma and nervures black; highly iridescent, a narrow 
irregular cloud along the transverse basal nervure, a broader one on either side of the 
base of radius, broader on the outer than on the inner side; sparsely covered with white 
hairs. Closely punctured, the apical half of the second abdominal segment and the whole 
of the others smooth, shining, and with a plumbeous hue. Base of mandibles and oral 
region dull rufous. @. 
Length 4 mm.; terebra 1°5 mm. 
Localities. Seychelles, Mahé. 
Head alutaceous, opaque; the face densely covered with short pubescence; the malar 
space tinged with fuscous; palpi long, black. Thorax more coarsely alutaceous than
