border and rounded posterior corners. Eyes large and very convex, 
at the middle of the sides of the head. Ocelli absent. Clypens nearly 
as long as broad, its anterior margin rounded, projecting far beyond 
the anterior border of the head over the bases of the mandibles, 
convex but not carinate in the middle. Mandibles long, with the 
external borders straight at the base and the apical borders with 
about 9 large teeth alternating with nearly as many smaller ones; 
the apical teeth longer and more curved. Frontal area and frontal 
groove distinct ; frontal 
carin ae short, subpar- 
allel, slightly diverg- 
ing behind. Antennae 
slender, 12-jointed, the 
scapes extending more 
than half their length 
beyond the posterior 
corners of the head, 
gradually incrassated 
towards their tips ; 
funicular joints slen-

ing in length distally, 
joints 1 and 2 subequal and fully 4 times as long as broad, the 
penultimate joints scarcely twice as long as broad. Thorax long and 
slender, much like that of Gesomyrmex , but with deeper and longer 
mesoepinotal constriction and longer pro- and epinotum. Petiole 
more than twice as long as broad, elongate elliptical from above, in 
profile bearing in its middle a low rounded node which is not com- 
pressed anteroposteriorly. Graster short, elliptical. Legs long, with 
stout claws on the slightly enlarged terminal tarsal joints and feeble 
spurs on the middle and hind tibise. 
Body, legs and scapes finely coriaceous or shagreened and very 
sparsely and finely punctate. Mandibles and clypeus finely, longi- 
tudinally striated, the former also with coarse, sparse punctures. 
Hairs very sparse, erect, visible only on the mandibles, on the 
venter and posterodorsal portion of the gaster. Apparently also the 
body in life was covered with fine dilute pubescence, but traces of 
this are distinctly seen only on the head of some of the specimens. 
Color varying from red to black; the darker specimens often 
showing signs of considerable decomposition. 
Male. Length about 8 mm; length of fore wing 10 mm.
