Cape Colony. Grahamstown (14th December). 



Antennae 29-jointed, stout, almost bare ; the third joint longer 

 than the fourth. Head and thorax smooth, thickly covered with 

 short, w T hite pubescence. Clypeus clearly separated ; the middle 

 separated from the sides by depressions. Parapsidal furrows dis- 

 tinct, the middle lobe distinctly separated. Abdomen short, not 

 quite so long as the thorax ; closely, minutely punctured ; the suturi- 

 form articulation is distinct, roundly curved towards the base of the 

 segment at the sides ; there is a narrow, but distinct furrow on the 

 apex of the second segment ; the segments laterally at the apex are 

 clearly separated. There is a deep, distinct, oblique furrow down 

 the middle of the metapleurae. 



Probably the amount of rufous colour on the head and thorax 

 varies ; the metapleurae may be rufous.
