Parasitic Hymenoptera. 465 
trochanters are yellow; almost the apical half of the hind 
tibiae is black ; the apices of the 2nd and 3rd abdominal 
segments are testaceous; but this may be the case with 
the 9. The median segment is more densely covered 
with long white hair than in the 2; the spines are darker 
and not so prominent; the contraction at the base of the 
hind tibiae is not so well marked. 
The keel dividing these 2 areae is roundly curved 
outwardly ; the apical slope is bordered above and late- 
rally by stout keels; on the inner side of the straight, 
bordering outer keel is a roundly curved one; on the top 
are a few short, broken keels;; the central 2 being longer 
than the others, they reaching almost to the apex. Meso- 
notum, except at the apex of the middle lobe, sparsely 
punctured ; the scutellum is more strongly punctured ; its 
basal depression is wide and deep and with a stout keel 
in the middle ; its apex has a stout, rounded keel. Upper 
part of mesopleurae almost smooth, the lower and the 
sternum strongly closely punctured; the furrow curved, 
deep, crenulated. Areolet 4-angled, the transverse cubital 
nervures separated in front. 
Agathinae. 
3. Agathis abuensis sp. nov. d.. 
Luteous, the hind tibiae, tarsi and calcaria and the 
antennae, black, the pubescence dense and pale; wings 
fuscous ; the anterior at the base to the transverse median 
and lower side of transverse basal, the cloud on the fore 
part of the latter covering it; a cloud, extending from the 
base of stigma to shortly beyond the areolet, yellowish 
hyaline; the hind wings yellowish hyaline, the apical 
fourth clouded, but not so deeply as the anterior wings; 
the stiema bright luteous. — Length 8—9 mm. 
Abu (C. G. Nurse). 
Areola square, smooth ; it is bordered by a triangular 
area, the apex of which is at the apex of the areola; out- 
side this is a larger, more irregular area, the apex of 
which is at the base of the metanotum. 
In one example, apparently of this species, the areola 
is triangular and the other areae differ somewhat in shape. 
a do not think that much reliance can be placed on the 
form of the metanotal areae with the Agafhinae as they 
appear, in some individuals of the same species, to be 
better developed than in others.
