strongly raised between the antennae and obscurely continued to the 
anterior ocellus. Eyes diverging towards the clypeus, the ocelli in 
a wide triangle, the posterior pair further from the eyes than from 
each other. Thorax subopaque, shallowly and sparsely puncturetl, 
the scutellum almost smooth. Median segment very sparsely and 
finely punctured, the triangular space at the base smooth and shining, 
with a faint median sulcus. Pleurae and abdomen deeply but not 
very closely punctured, the petiole about twice as broad as long ; 
pygidial area rugulose, about twice as long as broad, truncate at the 
apex, the sides almost parallel, slightly narrowed at the apex. 
Black ; a large spot on each side of the front below the base of the 
antennae, the scape beneath and the tibiae beneath yellow ; the fifth 
dorsal segment, the sides of the fourth more obscurely and a trans¬ 
verse spot on each side at the base of the second dark castaneons 
brown ; a dull ochraceous spot on the tegulae. Wings hyaline, the 
costa as far as the apex of the radial cell rather broadly fuscous ; 
nervures black. Length 12 mm.

9. Clypeus short and broad, the middle lobe twice as broad as 
long, porrect and deeply and widely emarginate at the apex, sparsely 
and shallowly punctured. Head much broader than the thorax^ 
closely but not very coarsely piinctured, shallowly on the front, more 
deeply on the vertex ; antennae inserted twice as far from the eyes 
as from each other, with a sharp longitudinal carina between them, 
the second joint of the flagellum as long as tbe first and third 
combined. Posterior ocelli fully twice as far from the eyes as from 
each other, the cheeks behind the eyes rather broader than the eyes. 
Thorax and median segment finelj' and rather sparsely punctured, 
shining, scutellum very sparsely punctured, the postscutellum and 
the triangular area at the base of the median segment smooth and 
shining. Abdomen smooth and shining, the basal segment more 
than half as broad again as long ; pygidial area finely granulate, 
widest in the middle, a little broader at the base than at the apex ; 
sixth ventral segment deeply emarginate at the apex, the angles pro¬ 
duced and showing as blunt tubercles beyond the dorsal segment. 
Pleurae striated, the upper portion of the mesopleui’ae punctured, 
the lower portion rugosely striated. 
Black ; the base of the mandibles, clypeus, front, scape beneath, 
cheeks, a spot on each side on the vertex, prunotum, tegulae, 
scutellum, postscutellum, mesopleurae, legs, a broad curved band on • 
each side of the median segment almost enclosing a large black spot, 
the third and fifth abdominal segments, the basal half of the second
