 pro- and metasternum bearing short erect setse, the middle 

 tibiiie with thick hair-fringes. The three terminal lamellae of 

 the antenna are moderately long and the preceding three 

 distinctly shorter. The fteftd is clasely and roughly i)unctured, 

 the median tubercle rather sharp, the frontal area triangular 

 and almost equilateral, the frontal tubercles rather strong, 

 the marginal ])rocesses acute, the left one more so than the 

 right. The pronotmn has a strong complete median groove 

 and there are scattered punctures before and behind the lateral 

 scar as well as a small crowded group of punctures near the 

 front angle. The lateral grooves of the elytra bear numerous 

 fine but distinct punctures. The median area of the rneta- 

 sternum has its hind angles coarsely rugose.
