ally twice as distant as either from the eye; sulcus obsolete 
near the frontal tubercle, the middle part of the vertex very 
convex. Antenne as long as the head and_prothorax 
together, the two basal joints stouter; seventh and eighth 
slightly larger than the preceding; ninth and tenth increasing 
in length and twice as wide as long; eleventh slightly wider 
than the tenth, twice as wide as long, and equal in length to 
the thre2 preceding joints, ovate, acuminate. /Prothorax 
slightly wider than long, slightly wider than the head, widest 
before the middle, broadly arcuate to the neck, sinuate behind, 
base three-fourths of the greatest width; disk convex, trans- 
verse sulcus deep, posteriorly angulate in the middle, where it 
is deeper; lateral foveze small, pubescent. /ytra, across the 
prominent shoulders, slightly wider than the prothorax, suture 
one-half longer than the prothorax; sides slightly arcuate, 
depressed, sutural lines arcuate, discal ones one-third the 
length, wide at the base; intermediate basal puncture very 
small. Addominal segments widest at the base, diminishing
