at the apex, longer than wide, extending slightly beyond the middle, there 
being a triangular space at the apex between them ; from the top of it a 
furrow runs to the apex. The basal two and the basal half of the third 
segments are closely longitudinally striated, the basal two with a not very 
strong keel down the centre ; there is a narrow but distinct furrow between 
the second and third segments ; the basal segment sessile, longer than 
wide, and a little longer than the second ; occiput and cheeks margined. 
Eyes incised on inner side. Legs stout ; the fore tarsi not much longer 
than the tibiae ; the metatarsus as long as the following two joints united. 
Spiracles small, round. 
The antennae are in the male fully longer than the body and taper 
towards the apex. The head is cubital, narrower than the thorax, the 
occiput is roundly incised ; the wings are large, yellowish hyaline and 
spotted with fuscous. The parapsidal furrows are distinct on apical half. 
Eirst abscissa of radius about one-fourth of the length of the second. 
The type of the genus has much more the look of one of the Exothecini 
than of the Boryctini , especially in its large size and colouration. In the 
arrangement of Szepligeti (Gien. Ins., Brae., 63) this genus would come 
in near Gymnobracon and Osmophila. It should be readily known by the 
two large roundly raised lobes on the metanotum and by the incised eyes. 
Xenolobus rufus, sp. n. 
Rufous ; the antennae, tips of mandibles, the four posterior tarsi, 
the apical joints of anterior and the hinder tibiae black ; wings yellowish 
hyaline, a large fuscous triangular cloud along the outer apical three- 
fourths of the transverse basal nervure, the apex all round from near the 
base of the stigma except for a large irregular oval hyaline cloud extending 
from near the costa to near the posterior margin, it extending into the 
first cubital cellule as a triangular projection along the radius, the apical 
fourth of the hind wings, the cloud extending backwards along the margin 
as a double triangle, of which the posterior is the larger and longer. Thorax 
and legs covered with short, white pubescence. Male. 
Length, 18 mm. 
Pretoria. November. 
Sides of face broadly, irregularly transversely striated ; the ocelli 
bordered by curved pyriform foveae, the space between which and the 
eyes is striated. Pro- and mesonotum punctured, the depressed apical 
central part of the latter longitudinally strongly striated, the striae more 
or less twisted. Scutellum sparsely punctured, the parts bordering it stoutly 
striated. Metanotal lobes shagreened, the rest irregularly reticulated ; 
the apical slope smooth, with two transverse stout keels. Basal two 
segments of the abdomen closely striated, the striae on the first more or less 
twisted, that on the apical half of the second much finer than on the basal, 
the striae on the basal half of the third finer than on the apex of the second. 
Cheloninae. 
Chelonus rufoscapus, sp.- n. 
Black ; a broad yellowish white band of equal width on the basal fourth 
of the abdomen, the antennal scape and the legs, except the coxae, red ;
