the stigma and the apex; the radial cellule foriniii}; almost a semi-circle; the 

 first transverse buUated below, obliquely sloped, more so than the second, which 

 is as stout as it ; the others are faint, thin. Head distinctly, but not closely or 

 strongly punctured; the front finely furrowed down the middle. Antennal 

 tubercles large, bare, shining. Mandibles slightly reddish near tlie middle. 

 Thorax more strongly, but not any more closely punctured than the head ; more 

 sparsely at the apex of the mesonotum in the middle. Scutelhini rugosely punc- 

 tured. Metanotum reticulated. Propleurse impunctate, bare below ; the meso- 

 pleurae distinctly punctured, except at the apex, which is smooth, bare and shin- 

 ing, as is also the base of metapleurse, the rest of the latter being reticulated, but 

 not so strongly as the metanotum. Abdomen shining, smooth ; the basal two 

 segments sparsely, the others thickly covered with long white hair; the apical 

 having also some black ones in the middle ; the pygidiuni is more opaque, rougher 

 and brownish at the apex. % . Length 5 mm. 



Antennal scape punctured, not hollowed below, as long as the following two 

 joints united ; the third joint narrowed at the base; not quite as long as the 

 fourth. There is no distinct areola on the base of metanotum. The abdominal 

 petiole becomes gradually wider from the base to the apex, which is not clearly 

 separated from the base of the second ; the segments are not keeled in the mid- 

 dle. Eyes shining, not strongly facetted, ovate ; there is a distinct malar space. 

 Head, rounded in front, transverse behind, the angles rounded.

Black, with the following parts red : the base of the post-petiole and the rest 

 of the abdomen, a large squarish mark in the centre of the mesonotum, extend- 

 ing beyond the apex of the tegulse and with the sides continued as moderately 

 broad lines to near the base, the second lateral arese on the metanotum, the 

 greater part of middle femora, of the hind coxte, the hinder femora and the 

 apical half of the hind tibife; bright yellow are: the clypeus, labrum, mandibles, 

 except at apex, the upper and inner orbits, the lower and the lower part of tlu- 

 outer shortly, a line on the upper part of prothorax, two spots on the lower edge, 

 tegulse, tubercles, the centre of the mark on the pronotum, the greater part of 

 the scutellum. apex of areola, the second lateral arese, the spiracular, except at 

 the base, the apices of the abdominal segments, the ventral keel, the four ante- 

 rior legs, except the femora, the apex of the hind coxte, trochanters and the base 

 of the hind coxae broadly black below. Antenna- black, the scape yellow, black 

 above. Wings hyaline, the costa and nervures black, the stigma dark fulvous. 

 % . Length 15 mm. 



Antennae distinctly tapering towards the apex, not serrate. Head, thorax and 

 coxfe densely covered with white pubescence, closely, but not strongly punctured, 

 except over each antennte, where there is a smooth, bare, shining depression, the 

 metanotum more strongly punctured than the rest, the posterior median area 

 coarsely, closely transversely striated. Areola large, horse-shoe shaped, longer 

 than wide, the base transverse in the middle, the apex rounded inwardly. Post- 

 petiole dejiressed in the centre, closely, somewhat strongly striated : the sides 

 sparsely punctured on the inner, striated on the outerside. Gastrjeceli deep.
