the male; the pygidium is obtusely produced, and the punctures 

 on it and on the propygidium are finer tlian those in the male; 

 the presternum and mesosternum agree in both sexes, but the 

 metasternum is much more coarsely and thickly punctured in 

 the female ; the fore tibiaj in both sexes have five or six strong 

 teeth on the outer edge and a large tooth on the inner side 

 near the base, whicli is very conspicuous in the male, but 

 shorter and more obtuse in the female ; in repose the large 

 tooth rests in a femoral cavity. L. 5| mill.

 L. 2f mill. 



Cylindrical, black, shining, lateral margin of the thorax at 

 base, outer margin of the elytra, and a broad band (diffused 

 rather than well defined) behind the scutellum, but not 

 reaching the sides of the wing-case, red ; male without ocular 

 tubercles ; the rostrum is parallel at the sides and ter- 

 minates in an obtuse point, the outer margin has a fine 

 carina, and a median ridge is just visible, the interstices are 

 shining and smooth ; thorax long, parallel and sparsely punc- 

 tate at the sides, punctulate on the disk, and nearlv smooth 

 before the scutellum ; behind the neck, about a fourth part 

 down the thorax, is a small tubercle ; the elytra are finely 

 and sparsely punctulate, with a red band, widest at the 

 suture ; propygidium and pygidium rather densely punc- 

 tate ; prosternum bistriate laterally, strise joining in front, 

 almost truncate at both ends; mesosternum arcuate at sides, 

 laterally striate, obtuse anteriorly; metasternum with a 

 remarkably deep sulcus in front, which occupies about one 

 third of its entire length. 



? . Forehead and rostrum somewhat uneven, rostrum 

 faintly impressed longitudinally, punctures much scattered in 

 the middle, clustered over the eyes ; thorax evenly but not 

 closely punctured ; elytra smooth at the base, punctulate 

 apically and partly up the suture ; propygidium and pygidium 

 evenly punctured, pygidium elongate, obtusely produced, 

 convex above, and beneath the apex is hollowed out ; the 

 three sternal plates agree with those of the male. 



The hinder tibife in both sexes are triangularly dilated.
