between the lateral ocelli, sides moderately convex. Eyes 
large, convex, suboval in outline, their margin bounded by 
a narrow and shallow groove, the posterior border lies at 
the middle of the side of the head, the anterior border sepa- 
rated from the insertion of the mandible by a distance 
equal to the thickness of the first funicular joint. Ocelli 
large and prominent, the two lateral ocelli separated from 
each other by a distance almost twice as great as that 
which separates each from the median ocellus. Clypeus 
subtrapezoidal, the median portion somewhat elevated, the 
anterior edge feebly sinuate. Mandibles small, rather broad 
at the base which bears a curious, oval impression, but with 
a narrow though rounded apex, entirely without teeth, An- 
tennae filiform, of thirteen joints. First joint cylindrical, 
about one and one-half times as long as thick; second joint 
thinner, more rounded, about as broad as long ; the remain- 
ing joints all much more slender, five times as long as thick. 
Thorax seen in profile with a feebly convex dorsum, the 
pronotum steeply declivious throughout, the small anterior 
portion forming the neck not well differentiated from the 
rest ; seen from above the pronotum is cresentric in outline 
and separated from the scutum by a very pronounced 
suture. Scutum subtrapezoidal, the anterior face evenly 
convex, its greatest width five-sixths of its length. Notauli 
(Mayrian furrows) absent, parapsidal furrows extending 
forward two-thirds of the distance to the anterior margin 
of the scutum. Scutellum small, rather convex, its dorsum 
triangular in outline but spreading ventrally to form a 
quadrate outline. Metanotum thicker and less arcuate than 
in the female. Epinotum seen from above tapering towards 
the rear, without sharp definition between the basal and 
declivious faces. Seen from the side the two faces appear 
as a continuous curve. Node of the petiole low and thick, 
the anterior face steeply declivious, the posterior face per- 
pendicular, the summit thick and evenly convex, the ven- 
tral surface without lobe or lamella. Gaster very elongate, 
its greatest width three-eighths of its length, a feeble con- 
striction between the first and second segments. 
Color dirty blackish brown, the thorax more or less 
marked with dirty yellow. The posterior gastric segments
