Differs from the other species of the genus in its broad 
Oodcs-Wkc shape, and in the thorax not being at all nar- 
roAved l)ehind ; also in the unthickened antennal joints. 
It has, however, the other chief characters of Stomonaxus. 
The anterior tarsi of the 2 have their 1st and 2nd joints 
produced at their inner apex into a long tooth ; the middle 
and hind tarsi are slender, smooth above and grooved only 
on the sides. The anterior tibias are dilated at the apex, 
and their rounded outer edge furnished with a row of ex- 
tremely strong spines.
