Long. i6 mm. 



Scape of the antennae reddish, yellowish on the under 

 side, the second and third joints deep black ; the rest 

 rufous, yellowish on the lower side. Head black ; the 

 face and clypeus, a small, somewhat triangular, mark 

 touching the top of the eyes opposite the ocelli, and the 

 outer orbits from shortly above the middle, yellow. Front 

 and vertex closely but not strongly rugose ; the inner 

 orbits distinctly margined ; above, and between the 

 antennae, is a stout keel, which becomes gradually wider 

 towards the apex ; the face is indistinctly longitudinally 

 keeled ; the clypeus is much less strongly punctured than 

 the face and, at the apex, is almost smooth. Mandibles 

 and palpi coloured like the face ; the mandibular teeth 

 black ; the vertex is thickjy covered with short, black hair. 

 Thorax black ; the edge of the pronotum at the base, a 

 narrow interrupted line on the sides, a broader line on the 

 side of the mesonotum extending from the middle of the 

 pronotum to behind the tegulae, and the apical half of the 

 metapleurae, rufous. Mesonotum very closely and 

 uniformly punctured ; densely covered with short, black 

 hair ; the scutellum is more strongly, and not so closely 

 punctured. The base of the median segment is closely 

 rugose ; in the middle are two indistinct keels forming an 

 area, the rest reticulated, thereticulations longer at the sides 

 and apex. The propleurae at the base minutely punctured 

 and thickly covered with whitehair, this part being separated 

 from the rest by a narrow keel ; the upper part behind 

 this is rather coarsely punctured, the lower more finely 

 and irregularly striated ; the mesopleurae closely punc- 

 tured ; the middle with an indistinct depression ; the 

 lower part at the base irregularly striated. At the
