Wings hyaline, the nervures black. Apex of scutellum ending 

 in two broad, rounded lobes. — Length fully 5 mm. 



Hab. Iudia. 



Antennae somewhat shorter and stouter than usual, the 

 flagellum covered with a microscopic down. Head, including 

 the face, coarsely and closely punetured, the clypeus less 

 strongly punetured; the pro- and mesopleurae more coarsely, 

 rugosely punetured; the upper part of the meso- at the base 

 smooth, except for a few striae; the lower part coarsely 

 reticulated ; the median segment strongly reticulated, more 

 closely and rugosely on the pleurae than on the metauotum. 

 The lower part of the hind coxae punetured and covered with 

 white pubescence ; the teeth on the basal half of the femora 

 are widely separated ; on the apical they are closer and smaller. 

 — The top of the mesopleurae is smooth ; below is a row of 

 large round foveae ; the dépression on the mesopleurae is 

 almost smooth in the centre, below and above striated ; the 

 mesonotum at the base is thickly covered with fuscous pube- 

 scence; the scutellum bears longer, paler hair.

Hab. India. 



Face and lower inner orbits opaque, closely rugose and 

 thickly covered with silvery pubescence; the smooth plate in 

 the centre is obliquely narrowed above and slightly, roundly 

 contracted in the centre. In the centre of the clypeus is a 

 band of large punctures. Apex of mandibles rufous. Pro-, 

 mesonotum and scutellum closely covered with large rouod 

 punctures. Apex of scutellum thickly covered with longish 

 silvery hair. There is a row of widely separated longitudinal 

 keels on the base of the metanotum, forming squarish areae 

 and with a stouter keel in the centre; the rest of the median 

 segment is coarsely reticulated. Propleurae irregularly 

 shagreened ; there is a stout, oblique keel shortly below the 

 middle, and a shorter straighter one lower down. The central 

 hollow of the mesopleurae is irregularly striated from near 

 the top; the striae on the widened lower part are divided by
