secundoque, tertio basi extrema, femoribus anticis subtus, inter- 
mediis dimidio apicali, supra nigro-lineatis, tibiis anticis interme- 
diisque, tarsisque anticis ferrugineis; petiolo segmento primo

Long., 2 18, d 16 mm. 
?. Mandibles with a long acute apical tooth and two 
strong teeth on the inner margin. Clypeus with sparse large 
punctures, microscopically punctured and pubescent; head 
subopaque, with sparse large punctures, a deep groove from 
the anterior ocellus to the base of the antennee. Eyes almost 
parallel on their inner margins; posterior ocelli much further 
from the eyes than from each other, separated from the eyes 
by a distance about one-third greater than the length of the 
third joint of the flagellum. Pronotum a little longer than 
the scutellum, nearly twice as broad anteriorly as long, with 
a deep median groove on the posterior half, rather strongly 
transversely striated. Mesonotum strongly transversely 
striated, with a deep median sulcus reaching almost to the 
posterior margin, where the striez are oblique. Scutellum 
and postscutellum longitudinally striated. Median segment 
rugose, with oblique striz, which are more distinct laterally 
than in the middle, First joint of the petiole black, almost 
exactly equal in length to the hind femur, a little longer than 
the second joint of the petiole; second tergite longer than its 
apical breadth. ‘Tarsal ungues simple, with a distinct pul- 
villus. Pleurze rugose, with more or less distinct oblique 
striz, evenly covered with very delicate whitish pubescence. 
Spiracle of the first tergite situated considerably behind the 
middle. 
3. One large tooth only on the inner margin of the man- 
dibles ; eyes converging towards the clypeus ; apical margin 
of the clypeus widely and shallowly emarginate; eighth 
sternite rather narrowly rounded at the apex. ‘Third cubital 
cell in both sexes small, contracted both on the radius and 
cubitus, second abscissa of the radius longer than the first in 
the female, a little shorter in the male, more than twice as 
long as the third.
