strip, dark brown, as is also a very broad band across the middle 
of the first abdominal segment and the basal half of each of 
the succeeding segments. Hairs covering the mandibles, anten- 
nze, legs and body, whitish ; those on the body rather long, coarse 
and truncated, but scarcely clavate 
at their tips; those on the limbs 
tapering and less conspicuous. 
Mandibles rather coarsely striated 
longitudinally and provided with a 
few setigerous punctures; cutting 
edges black. Clypeus moderately 
convex, smooth in the middle but 
with a few delicate longitudinal 
ruge on either side. Antenne 
11-jointed. Head opaque, above 
and on the sides coarsely and 
sp. longitudinally reticulate-rugose, the 
areole enclosed by the rugæ being 
indistinctly and finely punctate. In the mid-dorsal region 
of the head the rugz are close together and their longi- 
tudinal course is very distinct, but in the antennal fovez and 
on the cheeks and the sides of the head they are farther 
apart and more reticulate. Some of the workers have 
two or three minute ocelli which are most easily seen in alco- 
holic specimens. Thorax faintly but distinctly constricted at 
the meso-metanotal suture; opaque, above and on the sides 
less distinctly reticulate-rugose than the head. Anterior por 
tion of the pronotum, metanotum, and lower pleurz punctate ; 
metanotal spines slightly longer than broad at their bases, 
nearly parallel, terminating in broad, flattened, blunt points. 
Petiole about twice as long as broad, subopaque, finely punctate, 
with a pointed dorsal cone, the anterior and posterior surfaces 
of which are of nearly equal length and inclination, the former 
being very slightly concave, the latter flat when seen in profile. 
Postpetiole smooth, subglabrous, hemispherical. Abdomen 
rather broad, distinctly flattened dorso-ventrally, and very 
glabrous.
