no gastroceeli or transverse depressions; the last segment is 
largely developed all round; the ovipositor is elongate, 
‘The eyes are large and converge slightly above; the malar 
space is moderately large; the clypeus is separated from the 
face by a curved suture; the face is flat; the apex of the 
clypeus is depressed, clearly separated, and rounded., Man- 
dibles bidentate. The mesosternum is largely, deeply, and 
triangularly depressed at the apex ; there is a distinct longi- 
tudinal furrow on the lower side of the mesopleure. The 
head is narrower than the thorax; it is not much developed 
behind the eyes; the occiput is not quite transverse. ‘lhe 
Jast dorsal segment is semicircularly depressed at the base ; 
the metathorax is not produced beyond the insertion of the 
hind coxe. 
This genus is somewhat isolated and may, for the present, 
be placed in the Phygadeuonini; but it does not appear to 
have any near relationship with any known genus. — Its 
characteristic features are the long semiclavate antenne, the 
distinct parapsidal furrows, areolated metathorax, longish 
narrow areolet, and obsolete subdiscoidal nervure in hind 
wings. It has the appearance of a Zanthopimpla. The 
spiracles are placed further back (nearer the middle) than 
usual with the Cryptina, but not between the middle and the 
ase as with the Pimplides.

Antenne black. Head smooth, shining, and bare; the 
centre of the face bordered by two shallow furrows. Man- 
dibular teeth black. On the basal two thirds of the middle 
of the mesonotum is a large black line, which is somewhat 
dilated at the base and apex; there is a shorter broader 
mark close to the tegule, and the apex, with the scutellar 
depression, is black. The basal three arew of the median 
segment are broadly black. Pleura smooth, bare, and 
shining; the middle of the mesopleure is roundly raised and 
bordered by shallow furrows above and below; the furrow 
over the mesosternum is wide and smooth. ‘lhe basal three 
aree on the median segment are wider than long, the middle 
three almost square; the middle apical is slightly and gradually 
narrowed towards the apex. The base of the hinder coxe is
