singulo prsBdita, sutura baud elevata, margine lateral! acuta ; pedes 

 longi, graciles. Long. 19 mm. ; lat. 9|- mm. 



Closely allied to the preceding species, but distinguishable by 

 the much broader and more hexagonal prothorax ; the elytra are of 

 the same shape and sculpture, but there is hardly any trace of the 

 two reddish lines on each side of the discoidal carina.

Niger, opacus, prothoracis margine laterals, costis margineque 

 elytrorum ferrugineo rufescentibus ; caput prothoraceque crebre 

 profunde atque rugose punctati ; hie ampliatus in medio sub-angulatim 

 dilatatus, longitudine tertio latior ; elytra pone humeros modice 

 ampliata, in medio basi tertio latiora, versus apicem acuminata, 

 supra depressa postice convexa decliviaque, granulis minutis crebre 

 obsita ; costis tribus parum elevatis apicem baud attingentibus 

 utrinque prasdita, sutura baud elevata. Long. 19-21 mm. ; 

 lat. 8-10 mm. 



The prothorax is as broad as in the preceding species, but it is 

 not so angular in the middle, and the lateral margin is not at all 

 sinuate in the posterior part ; the elytra are depressed in the central 

 part for a short distance from the suture, and instead of there being 

 a sharp carina on each side, there are three blunt, moderately broad, 

 ferruginous raised lines which cease before reaching the posterior 

 declivity ; the surface is covered with sparse and minute granules.
