yellow : wings yellowish hyaline. the nervures yellow, black in the clouded 
parts, the stigma black: a cloud extends from the para-stigma to the apex 
of the stigma and to the opposite side of the wings, narrowed on the outerside 
from the disco-cubital nervure, a wider, fainter cloud in the apex of both wings, 
the areolet oblique, almost appendiculated, the apical nervure double the length 
of the first, the recurrent nervure received in the apical fourth. Female. 
Length 17 m.m. : ‘erebra 9 m.m. : 
Smooth and shining, covered closely with white pubescence, which is longer on 
the clypeus and median segment ; the pubescence on the legs closer and shorter. 
The basal depr ssion on the first abdominal segment is strongly keeled laterally ; 
there is a longish ovoid depression down the basal half of the second; it is 
strongly but not closely punctured. Sheath of ovipositor thickly covered with 
stiff black pubescence. The femoral tooth is broad, bluntly rounded at the 
end, longer on the basal than on the apical side. The apices of the scutellums 
are nar_owly deep blood-red. 
Neotheronia erythrea, spn. 
Ferruginous, darker co!oured on the apical half of the abdomen, the head 
except above, and the pleure, paler, more yellowish ; the hind legs coloured like

in the apical fourth ; it has a longish nervure on the outerside of the middle, 
the transverse median nervure interstitial. Female.

Smooth, shining, the mesonotum densely covered with short black pubescence, 
the face more sprasely with longer white pubescence. Clypeus separated from 
the face by a distinct furrow, which is transverse in the middle above, the sides 
roundly curved downwards. Malar space about one-half the length of the 
pedcile of the antenne. Metanotum with a stout curved keel at the top of the 
apical slope ; there is another on the apex ; there is a longish conical fovea on the 
top of the basal half, its sides distinctly margined ; there are no lateral keels. 
Scutellum with the sides keeled on basal third. Abdominal petiole nearly 
four times as long as wide ; an oblique depression on either side near the apex. 
Mand bles, pale yellow, the teeth black. Palpi rufo-testaceous. 
Neotheronia claripennis, sp.n. 
Head and thorax yellow, the abdomen brownish testaceous, an irregular line 
on the sides of the first, and slightly more than the basal half of the others black ; 
tips of mandibles, an irregular line joining the hinder ocelli to the eyes, a slightly 
narrower line round the apex of the vertex, three broad lines on the mesonotum, 
the central beginning at the base, the others beyond it ; the lateral depressions at 
the sides of the scutellums, a longish triangular mark on the apical half of the
