convex from the rear edge of the eye to the lateral ocellus. 
The occipital border is slightly concave between the lateral 
ocelli. Anterior border of the clypeus feebly sinuate. Man- 
dibles small, somewhat spatulate and with the teeth repre- 
sented only by a V-shaped notch on the masticatory margin. 
Antennal scapes long, surpassing the occipital margin by 
a little more than one-third their length. 
The greatest width of the thorax, when seen from above 
is approximately equal to that of the head. In profile the 
neck of the pronotum is short, the anterior face of the 
scutum is evenly rounded and its dorsal face is flat and on 
the same level as the anterior edge of the scutellum. The 
latter is convex in profile and descends sharply in the rear. 
In profile the epinotum is depressed well below the level 
of the scutellum, rounded and without a good separation 
between the basal and declivious faces. Petiole with a short 
but distinct anterior peduncle, the node low in profile, taper- 
ing slightly from base to crest with the latter evenly 
rounded. Seen from above the node of the petiole is trans- 
versely oval, with the width about twice the thickness from 
front to back. Gaster approximately as long as the thorax. 
Genitalia small and obscure. 
The surface is moderately to strongly shining. Front 
and genae strongly shining with scattered punctures. Oc- 
ciput and scutum less shining with a delicate reticulate 
sculpture. Scutellum very shining with scarcely any sculp- 
ture. The remainder of the thorax and the node of the 
petiole with a reticulate sculpture which is less pronounced 
than that of the scutum. Gastric sculpture very feeble, 
shagreened but scarcely reticulate, the surface more shin- 
ing than that of most of the thorax. Sparse erect hairs 
are present on the head, the coxae and the gaster. Thorax 
without erect hairs. Antennal scapes, the femora and the 
tibiae with very delicate, short, sparse hairs which are fully 
appressed. Pubescence on the antennal funiculi and the 
tarsal joints suberect and not particularly prominent. Tho- 
rax and gaster dirty, yellowish brown, the head distinctly 
darker. Wings hyaline and iridescent with the veins very 
pale.
