tured as the mesonotum ; the median segment stoutly 

 reticulated ; its apex oblique shining, not reticulated. 

 Propleurae smooth, piceous ; the base with some longitu- 

 dinal keels ; the apex fringed with woolly hairs ; the 

 mesopleurse coarsely rugosely punctured; the metapleurae 

 with an oblique smooth space in the centre, the base 

 and apex coarsely punctured. Legs obscure piceous ; 

 the femora darker ; sparsely covered with white hairs. 

 Wings hyaline ; the nervures and stigma fuscous ; the 

 first recurrent nervure received quite close to the trans- 

 verse cubital ; the second in the apical third of the 

 cellule. The basal three segments of the abdomen 

 rufous, widely suffused with black in the middle ; the 

 apical segments sparsely covered with white hairs ; the 

 ventral segments coloured like the dorsal.
