lOO Cameron, Hymenoptera Orienialia. 



the mesonotum marked with " une bande brune " ; but 

 the " metathorax is covered with fine curved striae, without 

 any other indication of the absence of the first division 

 than the absence of the strise above " ; here there are no 

 transverse striae ; there is a distinct transverse keel across 

 the middle, from which two finer keels run down to the 

 apex, enclosing a finely longitudinally striated space. 



Face and clypeus ferruginous, inclining to yellow at 

 the eyes ; the outer orbits and occiput entirely pale yellow; 

 the vertex darker ; the mandibular teeth black ; the face 

 and clypeus roundly projecting in the middle and not 

 separated. Antennae ferruginous, darker towards the apex. 

 Thorax pale fulvous-yellow ; the mesonotum of a darker 

 hue ; its middle lobe for the greater part dark fuscous, not 

 clearly defined from the lateral. Scutellum shining, 

 smooth, pallid yellow ; the sides not keeled above ; post- 

 scutellum distinctly raised ; its apex with an oblique 

 slope ; from its base a fine keel runs to the wings ; below 

 the keel there is a small striated band. The depression 

 in the middle at the base is broader than its length, 

 narrowed to a point in the middle at the apex and longi- 

 tudinally striated in the middle ; across the middle of the 

 median segment is a stout, transverse keel behind which, 

 in the centre, is a shallow depression ; the apex of the 

 segment oblique, the middle finely longitudinally striated. 

 Pleurae smooth and shining. Legs coloured like the 

 thorax. Wings hyaline, the stigma rufo-fulvous ; the 

 nervures black ; the apex of the cubital cellule is sharply 

 triangular ; the triangular part of equal length above and 

 beneath through the recurrent nervure being received 

 opposite the apex of the basal abscissa of the cubitus ; the 

 transverse median nervure is received immediately in front 

 of the transverse basal. Abdomen ferruginous : the base 

 of the petiole paler.
