compressed; eleventh slender, styliform. Thorax transverse- 
quadrate, sides nearly straight and parallel, obliquely narrowed 
just behind the anterior angles; above smooth and shining, dis- 
tantly punctured, impressed on either side, just behind the middle,

obtuse, conjointly emarginate at the sutural angle, strongly but 
not coarsely punctured; the surface of each elytron with about 
eight indistinctly raised longitudinal vittee.

This species closely resembles 7. impressa, Fab.; in the present 
insect the intermediate joints of the antenne are cyliferical and
