220 THE ENTOMOLOGIST. 



oblique shining truncation ; mesothorax and scutellum with extremely 

 close minute punctures ; scutellum not at all bigibbose or depressed in 

 the middle ; mesothorax with a good deal of appressed white hair, 

 very conspicuous but not covering the surface ; tubercles and post- 

 scutellum covered with coarse white hair ; basal area of metathorax 

 reduced to a narrow baud, with little transverse keels ; punctures on 

 posterior face of metathorax large ; tegulas reddish brown centrally, 

 otherwise yellowish hyaline ; wings almost clear, a little dusky at 

 apex; stigma rufous, nervures dark rufous; second submarginal cell 

 much higher than broad, receiving the first recurrent nervure before 

 its end ; legs with white hair ; spurs black ; hind legs scarcely modi- 

 fied, the tibiae somewhat produced at apex beneath, the spurs arising 

 from beneath the point ; abdomen shining but well punctured, the 

 punctures large on the first segment, smaller on the second, and 

 successively smaller and fainter on the following ones ; no distinct 

 hair-bands, but a scattered white pubescence, especially on the apical 

 half, and conspicuous erect white hair on the base and sides of the 

 first segment ; apex broadly truncate, with rounded corners ; no 

 ventral teeth, but first ventral segment raised in the middle. 



Hab. Queensland, 94. 61 ; also labelled Kidg., and 638. 

 Easily known from N. argentifrons by the normally formed hind 

 legs and the absence of pale reddish colour on the clypeus, 

 legs, &c.
