 conjunctis, pone medium sitis, exteriore interiorem superante antice pos-

Pale testaceous, the antennce slightly hirsute and the eyes 

 black : the prothorax has two black spines situated rather 

 nearer its anterior margin than the middle of the disk, and 

 behind each of these spines is a black tubercle, at about an 

 equal distance from the posterior margin ; on each of its late- 

 ral margins near the middle is another black spine, and on 

 each side before this is another small black tubercle : each 

 elytron has three ivory spots, one somewhat oval touches the 

 base, and is placed rather obliquely, the lower extremity be- 

 ing outermost, and bordered with black, the other two being 

 rather below the middle of the elytron, commencing nearly on 

 the same level, closely united at the upper extremity, then 

 separating, and the exterior prolonged much below the inte- 

 rior, each has a black mark at either extremity, the apical 

 ones are elongated ; the apical spine is black, and emits a 

 brown ill-defined line, which bends a little towards the exte- 

 rior margin of the elytron : the apices of the meso- and meta- 

 femora, as well as the spines, are black.
