diverging and dorsad extending to the apex of the vertex, the flagellum 
long and cylindrical, slightly thickening distad; antennze 13-jointed— 
scape, pedicel, 1 ring-joint, 7-jointed funicle and 3-jointed club; pedicel 
longer than the first funicle joint, the first and second joints of the funicle 
longest, the first joint the shorter of the two (Fig. 2). Mandibles 3- (left) 
and 4-dentate (right) (Fig. 1). 
Pronotum distinct, narrow, transverse mesially, widening laterad, the 
lateral wings being cuneate, mesially not longer than a fourth of the 
length of the mesoscutum; thorax flatly convex; parapsidal furrows dis- 
tinct, incomplete, inconspicuous, extending about one-half the length of the 
scutum, from the cephalic margin; axilla widely separated; mesoscutum 
elliptical in outline, both the cephalic and caudal margin being broadly 
convex, the caudal margin nearly straight between the axille and im-

pressed; scutellum with no transverse grooved line cephalad of the apex, 
but in its disk a few obscure, large punctures similar to those on the heads 
of many encyrtine genera, its apex broadly convex; mesopostscutellum nar- 
row, following the outlines of the scutellum, its cephalic and caudal margins 
ridged or carinate; metathoracic spiracle moderately large, elliptical-oval, 
oblique in position and nearly its own length from either the mesopost- 
scutellum or the lateral carina; median and lateral carine of the meta- 
thorax complete; median carina of the metathorax divided before base, 
each division proceeding latero-caudad to meet the lateral carine; the 
latter broken at caudal third; spiracular sulcus short, obscure. The whole 
of the head and thorax densely reticulated, amounting to punctation, the 
metathorax more coarse, punctate and rugose; abdomen finely, delicately 
reticulated, polished, the coxe finely reticulated, nearly smooth.
