 flagellum, a line on the pronotum, tegulae, tubercles, the base and 

 sides of first abdominal segment, the sides of the others more or less 

 and the greater part of the ventral surface, rufous. Wings hyaline, 

 the apex in front slightly smoky. Legs rufous. $ •

Metanotal area with some stout, irregular, curved striae. Front 

 and vertex closely, regularly, and strongly punctured ; antennal 

 area large, raised, rugose and bounded laterally by curved keels. 

 Clypeus strongly, but not so closely, punctured as the front ; the 

 cheeks almost smooth. Labrum rufous ; the top broadly, roundly 

 raised ; the apex depressed, obliquely narrowed, aciculated and with 

 a few scattered punctures. Mandibles black and rufous. Meso- 

 notum closely, strongly and distinctly punctured ; the scutellum 

 as strongly, but not so closely punctured. Pleurae and breast 

 coarsely rugose and thickly covered with white pubescence ; the 

 metanotum more closely rugose. Post-scutellum opaque, very 

 sparsely punctured. Abdomen smooth, the apices of the segments 

 with a narrow band of white pubescence. Both the recurrent 

 nervures are interstitial. The male wants the red lateral marks 

 on the clypeus. Both sexes vary in the amount of the rufous colour 

 which they bear ; the yellow line on the pronotum may be tinged 

 more or less with rufous. The malar space obsolete.

 closely punctured ; the face and clypeus with the punctures large 

 and distinctly separated ; the metanotal area irregularly longi- 

 tudinally striated. First recurrent nervure received in the apex 

 of the first cubital cellule, the second interstitial. Between the 

 antennae are two stout keels which are roundly curved above, and
