the marginal vein very short, the stigmal longish and clavate, the 

 post-marginal indistinct and little developed. An oblique, hair- 

 less, transverse line, narrow above, extending from or near the 

 marginal vein, is easily seen. Abdomen short, triangular, about 

 as long as the thorax, concave above, the ovipositor very slight- 

 ly exserted, the hypopygium not prominent. The general ap- 

 pearance of this genus is rather similar to that of Parcncyrtus 

 Ashm. 



Male differs greatly from the female in the comparatively 

 small and widely separated eyes, the ocelli in an almosf equi- 

 lateral triangle, and the very dense surface sculpture of the head, 

 and the more hairy antennae, with small club-joint; the meso- 

 notiim, scutellum and head are similarly dull and densely sculp- 

 tured.

een. nov. 



In general appearance very like the preceding genus, but the 

 head is perhaps rather more menisciform; the front between the 

 ejie-margins is much wider, the width, in a front view of the 

 head, through or near the anterior ocellus is about equal to the 

 width of one of the eyes. The system of large punctures on the 

 head is much more distinct and the punctures larger, though not 

 dense, and becoming sparser towards the facial impression. The
