Not less distinguished than tie former, especially by the round- 
ed shape of the thorax and the 5 yellowish spots with which the 
elytra are adorned. These are arranged in the following manner : 
2 small ones at the shoulders, 2 large transverse ones at the mid- 
dle stretching from the external margin towards the suture reach- 
ing, however, but little more than half across, 1 at the apex ; this 
is of the shape of a hammer, and half in one and half in the other 
elytron. The palpi appear to me longer and more markedly 
elbowed at the joints than is usual with insects of this genus, the 
last joint is deeply excavated at the tip. The thorax is of sub- 
orbicular form, the back and hind part are flat, the sides slightly 
depressed, the margin sharp, the basal impressions very near the 
angles : it is, as are also the elytra, rough and finely pubescent, the 
striae of the latter being thereby rendered obsolete. Legs of m. 
stout, anterior tarsi strongly dilated.
