Entirely black, except the pale calcaria and apices of 

 the tarsi ; and, besides the colour, differing from any of 

 the preceding in having no tubercle between the antennae, 

 and no transverse carina on the clypeus, but a narrow 

 raised line runs from the central ocellus to between the 

 antennre ; petiole of the body with a smooth, raised 

 central carina ; the S differs further in having the 7th 

 segment of the body clearly visible from above. 



Length 7 — 8 mill.

Like HHicolov in colour, but easily distinguished by the 

 sculpture of the petiole ; in this species the petiole 

 is flat, gradually widening to the apex, and bears two 

 raised lines which unite at the apex, making a sort 

 of lanceolate inclosure ; the apical segment of the body 

 in the ? is also very different, in unicolor it is widely 

 flattened above, dull, and largely and closely punctured ; 

 in this species it is shining, narrowly flattened, with 

 a carina on each side, and a slightly raised line in 

 the middle, punctured between the elevations ; the 3 

 difters also in having a raised line on the under side of 

 the 9th and 10th joints of the antennae. 



Length 7 — 9 mill.
