funicle half as wide, transverse, ninth and tenth longer and 
wider, transversely oval; eleventh larger, little longer than 
wide, annulated, acuminate. Last joint of the maxillary palpi 
short, conical. Prothorax as wide as the head, widest on the 
anterior third, about one-sixth wider than long, sides arcuate 
throughout, more so anteriorly, base continuously and slightly 
arcuate with the sides, neck one-half as wide as the pronotal 
width and two-thirds as wide as the base; disk slightly convex, 
with an oblong fovea before the middle, and one-third from the 
base, is a deép, angulated, sulcus connecting the large, pubes- 
cent, fovese. lytra, across the high shoulders, as wide as 
the prothorax, sides slightly and arcuately divergent, the disk 
nearly quadrate, not very convex; the sutural lines are close, 
nearly parallel, discal lines half the elytral length, emerging 
from the outer basal foveze, which are large and pubescent; a 
third intermediate basal puncture is also present. Addomen 
narrower at the base than the elytra, wider across the third 
“segment, the first two basal segments with short divergent 
carine. Legs strong, the tibia of the male dilated on the 
discal half. The third ventral in the male is sinuate in the 
middle, tumefied at the sides of the posterior limit; beyond 
this, on each side, is a long, externally arcuate spine, contigu-
