Head smooth, with a longitudinal impression extending from 
the centre of the face to the anterior stemma; the face very de- 
licately longitudinally striate ; the antenne with the basal joint 
piceous above and ferruginous beneath, the remainder of the 
joints also of the latter colour, slightly darker above ; the man- 
dibles testaceous, with their apex piceous, and the palpi tes- 
taceous. 
The thorax smooth; the collar longitudinally striate ; the 
dorsolum with two slight, longitudinal, elevated lines in the 
centre at its base, extending to the middle of the disc, on each 
side of which it has also at the base a deep longitudinal abbre- 
viated impression; the epaulets of the tegule consute, as well as 
the incisure which separates the scutellum from the dorsolum ; 
the scutellum itself sometimes with a central longitudinal im- 
pression; the metathorax rugose, with the superior surface 
having a central longitudinal carina, and another on each side 
of it slightly curved; the tubercles with a pale lunule; the te- 
gulz testaceous; the wings iridescent, the stigma and nervures 
piceous, the recurrent nervure joining the first submarginal cell 
at about two-thirds of its length; legs black, entirely simple, 
with the anterior and intermediate tibize and tarsi, and the pos- 
terior knees and tarsi, ferruginous. 
Abdomen black, smooth, and shining, attached to the thorax 
by a long petiole, which has a longitudinal carina running on 
each side, with the interstices shagreened 9. 
The ¢ differs in having the face covered with a silvery pubes- 
cence, and the parts, which are testaceous and ferruginous in 
the 9, yellow, with the exception of the tegule, which are pi- 
ceous, and the exterior of the intermediate tibize also piceous,
