apex. Median segment, except at the base, closely punctured ; in 

 the centre of the base is a large, somewhat pyriform fovea, the 

 narrow end at the base. Second cubital cellule almost sessile, the 

 nervures uniting at the top. Tibiae spinose, the hinder almost 

 serrate behind, the fore tarsi fringed with long stiff spines on the 

 outer side ; the hinder have also long stout spines as well as short 

 ones. 



The front below the ocelli is roundly raised ; immediately behind 

 the dilated part it is furrowed ; there is a longish, distinct ovate 

 fovea below the top of the frontal keel ; the basal half of the meta- 

 notal fovea is not so much depressed as the apical ; it has a stout 

 keel in the centre and its sides are also keeled.

Black, the basal four joints of the antennas, the clypeus except in 

 the middle at the base, mandibles except the teeth, fore legs, the 

 middle in front and the tegulae, brownish castaneous ; wings hyaline, 

 a not very distinct cloud in the basal half of the radial cellule, in the 

 apex of the first cubital, the second and third cubitals, and along 

 both sides of the recurrent nervures. $ .

Hind femora without a tooth. Basal part of metanotum closely, 

 uniformly, and distinctly transversely striated ; the apical slope 

 smooth, thickly covered with silvery pubescence ; there is a narrow 

 longitudinal keel on the basal half. Lower part of front and clypeus 

 thickly covered with silvery pubescence. Apex of clypeus almost 

 transverse, the middle with a slight shallow incision. Antennal 

 scape as long as the pedicle and first joint of nagellum ; the pedicle 

 about three times longer than wide. Head opaque, wider than the 

 thorax ; a shallow furrow in the centre of the front and a wider, 

 deeper one on either side of its apical half. Eyes slightly but dis- 

 tinctly converging above. Pleurae alutaceous, the apex of the meta- 

 irregularly obliquely striated. Tubercles castaneous, fringed behind 

 with silvery pubescence. First abdominal segment becoming gradu- 

 ally wider towards the apex ; if anything longer than the second ; 

 the penultimate broadly castaneous on the apical half ; the pygidium 

 rufo-testaceous, shining, bare, strongly but not very closely punc- 

 tured, the apical half of hypopygium similarly coloured. 



The tibiae and tarsi are sparsely spined ; the spines long and
