2IO Cameron, Hymenoptera Orientalia. 



the third ; there is no areolet in the fore wings ; the 

 scutellum is large, pyramidal, broadly keeled laterally ; 

 the median area has only the basal or middle arese 

 defined, and is laterally armed with large teeth or with a 

 plate. Eyes large, widely distant from the base of the 

 mandibles ; behind them, at the top, the orbits are hardly 

 developed and they are distinctly margined next to the 

 eyes. Antennae dilated and compressed towards the apex. 

 Clypeus not distinctly separated from the face ; foveate 

 on the sides at the base ; its apex rounded. Mandibles 

 triangular, with only one apical tooth. Thorax large, 

 with indistinct parapsidal furrows, the mesopleurse with a 

 longitudinal furrow on the lower side. Abdominal petiole 

 large, its apical half dilated ; there are no gastrocoeli. 

 The last ventral segment is large ; the ovipositor 

 originates from its base. The base of the basal joint of 

 the fore tarsi is largely curved, almost incised ; the long 

 spur of the tibi^ is curved. 



The form of the abdomen — in having only three 

 dorsal segments visible — resembles that of Rothneyia, but 

 in other respects it is very different from that genus.
