7 (8) Pterostigma testaceous throughout, the first abscissa of the 
radius two-thirds of the length of the second ; length 9 mm. 
pallidistigmus . 
8 (7) Pterostigma fuscous, broadly pale at the base, the first abscissa 
of the radius as long as the second ; length 6 mm. latisulcatus . 
Alysiinae. 
Coelalysia, gen. nov. 
Metanotum irregularly areolated ; the spiracles small, longish oval. 
Parapsidal furrows deep, distinctly defined, converging towards the apex. 
Scutellum large, flat. Post-scutellum raised, the sides bordered by stout 
raised keels. Radial cellule large ; the first abscissa of the radius one- 
fourth of the length of the second, which is shorter than the first transverse 
cubital nervure ; the recurrent nervure is received in the second cubital 
cellule ; the radius issues from the apical fourth of the stigma ; the second 
discoidal cellule is open at the apex below, the nervure being distinctly 
bullated there. Mesopleural furrow crenulated. The first abdominal 
segment is striated, the others smooth and shining, with narrow furrows. 
The third antennal joint is distinctly shorter than the fourth. 
The eyes are rather small, oval ; the malar space is not half their 
length. Clypeus separated from the face, which is more convex and 
rounded. The upper mandibular tooth is longer and more sharply pointed 
than the lower ; the two are clearly separated. Calcaria short, the claws 
slender, simple. The second cubital cellule is large, narrowed towards the 
apex and five-angled ; the transverse median nervure received beyond the 
transverse basal. 
In the arrangement of Szepligeti (Glen. Ins., Braconidae, p. 205), this 
genus runs near to the little known genus Symphanes , Foer., which may 
be known from it by the third and following abdominal segments not being 
clearly separated, by the metanotum not being keeled, and by the third 
and fourth antennal joints being of equal length. 
Coelalysia lutea, sp. n. 
Luteous ; the flagellum of antennae, inner mandibular tooth, ocelli, 
the greater part of the sixth and the following two abdominal segments, 
black ; the hind tibiae and metatarsus blackish ; wings hyaline, the stigma 
and nervures black. Smooth and shining ; the metanotum with a stout 
keel down the middle, the sides with a thinner keel which curves roundly 
outwardly at the base ; on the sides of the apical slope is a rounded keel. 
Apex of first abdominal segment distinctly, but not closely, longitudinally 
striated, the other segments smooth and shining. The third joint of the 
antennae is distinctly shorter than the fourth. The space between the 
parastigma and stigma is pale. Male. 
Length, 4 mm.

The metathorax is densely covered with longish white pubescence, 
its base is smooth ; in the centre of the apex are two keels which roundly
