no gastrocoeli or transverse depressions ; the last segment is 

 largely develoi)ed 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 lace is flat; the apex of the 

 clypeus is depressed, clearly separated, and rounded. Man- 

 dibles bidentate. The mesosternuni is largely, deeply, and 

 triangularly depressed at the apex ; there is a distinct longi- 

 tudinal furrow on the lower side of the mesopleura?. The 

 head is narrower than the thorax ; it is not much developed 

 behind the eyes ; the occiput is not quite transverse. The 

 last dorsal segment is semicircularly depressed at the base; 

 the metathorax is not produced beyond the insertion of tiie 

 hind coxee. 



This genus is somewhat isolated and may, for the present, 

 be placed in the Phygadeuonini ; but it does not appear to 

 have a)iy near relationsliip with any known genus. Its 

 characteristic features are the long semiclavate antenna-, 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.

Antennje 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 tegulse, and the apex, with the scutellar 

 depression, is black. The basal three areaj of the median 

 segment are broadly black. Pleurae smooth, bare, and 

 shining; the middle of tiie mesopleura3 is roundly raised and 

 bordered by shallow furrows above and below ; the furrow 

 over the mesosternum is wide and smooth. The basal three 

 areae 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 coxte is
