JAMES WATERSTON. 



anterior tibiae and tarsi, but somewhat dusky on the hind tibiae ; denticles of the 

 femur black ; claws dark brown, only the tips blackish. Wings unhanded and 

 immaculate ; hyaline near the base, but a little tinted elsewhere so as to appear dusky, 

 especially below the marginal and on apical half ; veins still more infuscated. 

 Pubescence silvery white, darker on dorsum of abdomen posteriorly. 



Head exceeding the thorax, but less than the extended tegulae in width ; deeply 

 excavated behind the scapes, the depression flanked by raised ridges along the orbits. 

 Eyes large, separated on the vertex by one and one-third diameters. Antennae : 

 length, 2 '2 mm. Scape broader basally and contracted subapically, w^here the 

 proportion of length to breadth is as 9 : 1 ; pedicel short, about one-fourteenth of 

 the scape and two and a half times as long as the minute ring joint. First funicular 

 joint longest, a little swollen dorsally ; funicle cylindrical, tapered off slightly on the 

 club ; proportions, 20 : 17 : 16 : 15 : 14 : 13 : 13 ; and club, 10 : 14— there being 

 only one clear suture. Average breadth of funicle, 15, so that the last four joints are 

 transverse.

Thorax with thimble-like punctures all over, rather shallow and not closely set ; 

 the integument between roughened, finely reticulate. Prothorax descending abruptly 

 behind the occiput, narrow medianly, expanded at the sides anteriorly, w^ith a strong 

 ridge which is much raised laterally, and indistinct only narrowly in the middle ; 

 mesonotum in the form of a long isosceles triangle, narrowing evenly backwards from 

 the suture with the prothorax to the apex of the scutellum, which lies just over the 

 insertion of the petiole. Scutellum bidentate, the teeth approximated and so 

 connected medianly that the concavity between is somewhat shallow. 



Propodeon triangular. The spiracle narrow and long, with one low pro ection 

 behind, which being upturned is very inconspicuous from above. The central cell 

 is broad, with an indistinct transverse ridge and two punctures before the petiole ; 

 on either side are three large cells, bounded outside by the inner ridge, before the 

 notopleural edge. The cell between the ridge and the edge is oblong (with 4-5 indis- 

 tinct transverse ridges) extending nearly to the spiracle and entirely covered with 

 refringent bristles. There is one large cell in the angle before the spiracle and another 

 behind it. Immediately behind the metanotum there is a row of indistinct punctures ; 

 the metapleurae are swollen and covered with short bristles.
