Nearly opaque, dull ferruginous-red, the head except the 

 front and the elytra except the extreme base, pitchy-black. 

 Antennae ferruginous. Legs reddish-testaceous. Length 

 2 mm. 



Distinct from all the known species by the colour. Head 

 narrower than the thorax, the eyes large and prominent 

 occupying the whole of the side of the head up to the 

 constriction of the neck; rather coarsely, closely and rugosely 

 punctured, in front rather less coarsely, the antennae tubercles 

 shining and impunctate. x\ntennae with •2nd joint short and 

 stout, the 3rd a little longer and more slender, 4th and 5th 

 subquadrate, as long as broad, 6th moniliform, 7th to 10th 

 transverse, gradually increasing in width, the 10th fully twice 

 as broad as long, 11th stout, conical. Thorax distinctly 

 transverse, the sides very slightly rounded and finely 

 denticulate in front, the posterior third almost straightly 

 narrowed to the rounded posterior angles ; the disc in front 

 feebly longitudinally impressed, posteriorly with a deep 

 transverse impression connected on either side with a large, 

 deep, opaque impuncate impression adjacent to the posterioi" 

 third of the sides and in front of this with a shallower oval 

 fovea; sculpture very similar to that of the head. Elytra 

 broader and longer than the thorax, longer than broad, the 

 disc of each with 4 longitudinal keels, the external one very 

 obsolete, more visible behind, the 1st (sutural) connected in 

 a curve with the 3rd behind the 2nd and shorter keel, the 

 whole surface covered with irregular rugose, more or less 

 longitudinally confluent and somewhat superficial sculpture. 



Abdomen coriaceous, scarcely punctured.
