the head, almost minutely punctured; there is a deep, clearly defined, crenulated 
furrow below the middle of the propleurse. Parapsidal furrow narrow, obscurely 
crenulated; the apex of the metanotum is more roughly punctured than the rest, almost 
finely reticulated; in its centre are two stout, parallel keels. ‘The basal segment of the 
abdomen is one-half longer than it is wide at the apex; it is closely, finely, longitudinally 
punctured ; bordering the middle of the base ate two keels, the basal half of the second is 
more finely punctured; the second segment is as long as the following two segments 
united; the apex of the punctured basal part is rounded. ‘Che wing-nervures are stout, 
deep black; the base of the stigma is broadly clear white; the basal abscissa of radius 
slightly more than one-third of the length of the second. Antennze longer than the 
body, slender, the base of the flagellum fuscous, 
This species seems to be a Camptocentrus as defined by Kriechbaumer (Berl. ent. Zeit. 
xxxix. 61); but Szépligeti (Gen. Ins., Braconidee, 84) sinks it in Rhogas. The species 
referred to it are African,

TOLBIA, gen. nov. 
Antenne longer than the body, of equal thickness ; the third and fourth joints almost 
equal in length; there are 25 joints. Stigma large, thick, long, becoming gradually 
narrowed to a point at the apex; the radius issues from near its base. Radial cellule 
long, extending to the apex ; the first abscissa of the radius minute, the second about one- 
fourth of the length of the third; there are three cubital cellules—the first wider than 
long, the second twice longer than it is wide at the apex, it receives the recurrent nervure 
close to its base; the transverse median nervure interstitial. In the hind wings the 
only closed cellule is the costal, which becomes widened towards the apex. Head as wide 
as the thorax; the temples wide, roundly narrowed; the occiput not margined, not 
transverse. Scutellum large, raised, rounded, the basal transverse furrow distinct: 
crenulated. Postscutellum flat. Metanotum large, broadly rounded at the apex. 
Abdomen broad, narrowed at base and apex; the first segment triangular, becoming 
gradually widened towards the apex, the base narrowed to a point. Legs long, slender, 
the spurs minute, the hinder metatarsus as long as the following two joints united. The 
first cubital and the first discoidal cellules are separated. The second and third segments 
of the abdomen are aciculated; they are both large; the suture separating them narrow, 
but distinct. The abdomen is hardly so long as the thorax ; there are at least six segments. 
The second abscissa of the radius is distinctly longer than either of the transverse cubitals ; 
it does not form an angle with the first. ‘There are no parapsidal furrows; the radial 
cellule and the second discoidal cellules are closed; the former is closed in front by a 
(listinct nervure; there is a distinct parastigma. 
Comes near to Sathra, Foer.; in that group the first abscissa of the radius is wanting 
entirely. In the recurrent nervure being received in the second cubital cellule it agrees 
with Misophthora, Foer.; but in that genus the stigma is not thickened as it is in the 
present.
