 the third and fourth together, the mandibles are rufescent, moderately 

 short and simple inwardly ; thorax nearly straight at apex, slightly 

 ampliated diagonally laterally from the apical angle to two-fifths of 

 the length, and distinctly tuberculate there, attenuate diagonally 

 from there to the posterior declivity which is nearly vertical, and 

 where it is narrower than the apical part by one-fifth ; the apical 

 and lateral sides are crenulate, and the upper part covered with deep, 

 round foveae with narrow walls ; the fovese are still broader in the 

 declivity ; abdomen sessile ovate, first segment vertical, dentate on 

 each side of the base, covered, like the second segment, with deep, 

 elongate punctures, the walls of which in the latter are raised and 

 somewhat strigillate ; the other segments are deeply punctured, and 

 fringed with a whitish flavescent band narrower than on the second 

 segment, and as distinct underneath as on the upper part ; the whole 

 of the last segment is closely and finely striate from apex to base ; 

 ventral carina of the first segment truncate at base, angular behind, 

 and sloping towards the apex ; legs black with the tarsi sub-rufescent,
