tellutn rounded, black, and glabrous. Elytra black, broad at the 

 base, gradually tapering to the apex, where they are slightly divari- 

 cate, truncate, and furnished with a small obtuse and obscure tooth 

 in the middle as well as at each angle of the truncature : each elytron 

 has three carinse ; the first is prominent, originates near the base, and 

 curves towards the suture but without reaching it, terminating in the 

 apical area ; the second originates on the disk considerably below the 

 humeral angle, and running parallel vrith the first, unites therewith 

 in the apical area ; the third is nearly obsolete ; it is situate on the 

 apical half of the elytron, between the second carina and the costal 

 margin ; the costal margin is pitchy red, and clothed with a grey pu- 

 bescence : the wings are fuliginous, slightly longer than the elytra, 

 and unfolded : the legs are rather long ; the metatibise slightly in- 

 curved, and furnished with two apical spines : the under surface of 

 the thoracic and abdominal segments is of a pitchy red colour, clothed 

 with a sparse grey pubescence ; the legs are of a similar colour, but 

 the pubescence is scarcely observable. 



Fem. — Head somewhat cordate, black, velvety, with a large ful- 

 vous spot occupying the face and extending to the epicranium be- 

 tween the eyes, but not reaching the anterior margin of the pro- 

 thorax ; a deep longitudinal epicranial sulcus extends forwards to 

 between the bases of the antennae : eyes arcuate, reniform, pitchy 

 black : antennae more than half the length of the body, 11-jointed; 

 the first joint rather short, somewhat obconical ; the second very 

 short ; the third the longest, but still not disproportionately so, di- 

 lated at the apex ; the fourth and fifth of the same form, but shorter ; 

 the remainder, to the eleventh, slender at the base, but dilated and 

 somewhat cupshaped at the apex, receiving into the cup the base of 

 the next succeeding joint, and being produced into a strong obtuse 

 lobe, tooth, or serrature on one side ; this is very conspicuous, and 

 gives the antenna a subserrated appearance ; on the opposite side is a 

 very slight, scarcely perceptible indication of a like lobe ; the eleventh 

 joint is sesquialterous. Prothorax nearly equal in length and breadth, 

 the anterior narrower than the posterior margin, the lateral margins 

 uneven and slightly lobed in the middle ; pronotum uneven, vnth a 

 slightly impressed anterior and posterior submarginal transverse sul- 

 cus, velvety black, with two broad irregular longitudinal vittse of a 

 bright fulvous orange colour ; prosternum produced between the pro- 

 coxEe, and the process notched. Scutellum short, rounded, black, 

 shining. Elytra at the base much wider than the prothorax, gra- 

 dually narrowing to the apex, where they are slightly dehiscent, trun- 

 cated, and the truncature produced in the middle into an obtuse, 

 scarcely perceptible tooth ; each elytron has three carinae ; the first is 

 prominent, originating near the base, and curves very gradually to- 

 wards the suture without reaching it, terminating in the apical area ; 

 the second is indistinct, originates near the humeral angle, and run- 

 ning parallel with the first, ceases in the apical area ; the third is still 

 less distinct, and its limits are obscure ; at both extremities a junction 

 between the first and second carinse may be made out, but is not very 

 manifest : the wings are fuliginous, slightly longer than the elytra,
