Long, corporis $ 23'5 — 28 mm. 



„ forcipis (? 4— 4'5 mm. 



Large and powerful, almost smooth, excessively finely punctulate, shining, with 

 a dense yellowish pubescence and numerous bristles. 



Antennae with 35 segments, all cylindrical ; the first is long, the second quite 

 short ; the third about twice as long as the second ; from 4 to 10 are short, and the 

 rest longer ; reddish-browu. 



Head broad and flat ; smooth, the sutures not very distinct ; testaceous above, 

 with a black border all round, and a black median stripe in the anterior part, and 

 a small black spot just inside the eyes, which are large and black ; under-surface of 

 the head shining reddish. 



Pronotum flat, subquadrate, but somewhat longer than broad, the angles all 

 rounded ; pro- and metazona scarcely differentiated ; testaceous, with two very 

 irregular black bands and black humeral markings. 



3Iesonotum very ample, a little longer and distinctly broader than the pronotum, 

 the shoulders bent down over the pleurae like elytra, but not keeled there and 

 scarcely folded ; testaceous, with black irregular markings, of which the main 

 pattern is a pair of black bands, remote anteriorly, converging posteriorly, nearly 

 meeting, and then suddenly diverging near the posterior margin. 



Mefaiwttnn formed and coloured like the mesonotum, but posteriorly strongly 

 sinuate. 



Elytra and wings entirely absent. 

 Prosternum distinctly narrowed posteriorly. 



Sternal plates and first few ventral plates all shining reddish-testaceous. 

 Femora and til)ix compressed, testaceous, sometimes marbled with black. 

 Abdomen smooth, broadening gently towards the apex ; first four segments 

 yellowish, marked with black ; then gradually darker, till the apical segments 

 are all black. 



Last dorsal segment large, square, very finely punctulate, with a median longi- 

 tudinal sulcus ; posterior border obtusely convex, depressed over the insertion 

 of the forceps, and the outside angles produced to form a small angular projection. 



Penultimate ventral segment very large, smooth, and shining ; strongly convex 

 in outline, and rounded apicaliy, just showing a corner of the last ventral segment 

 at the angles. 



Pygidium not visible. 



Forceps with the branches very stout, triquetrous, contiguous and broad at the 

 base, not toothed, but strongly crenate on the inner margin near the base ; about 

 half way down attenuated, the apices fine and hooked, the rigiit branch bent 

 over the left.
