184 EuBRIK Strap, 
eination; the apex not produced, an elevated transverse carina 
nearer to the base than to the apex, shining and almost smooth. 
Mandibles bidentate, not elbowed. Head finely and very closely 
punctured, the antennae inserted a little nearer to each other than 
to the eyes, nearly as long as the head, thorax and median segment 
combined, the apical joints arcuate. Thorax and abdomen finely and 
elosely punetured; the punctures on the pronctum very shallow, the 
anterior margin raised. Median segment rounded, more shallowly 
punctured than the mesonotum; abdomen narrower than the thorax, 
tapering slightly to the extremities, longer than the head, thorax 
and median segment combined; the first segment rather slender at 
the base, shining and less strongly punctured than the others. 
Hypopygium narrow, the sides parallel, short, scarcely projecting 
beyond the dorsal segment and blunt at the apex. Second recurrent 
nervure received at one third from the base of the third eubital cell. 
Black; elypeus (except at the extreme apex), a spot at the base 
of the mandibles, the margins of the eyes very narrowly as high as 
the base of the antennae, a transverse line on each side on the 
posterior margin of the head, a short oblique line above the base of 
each antenna, the anterior margin of the pronotum, the posterior 
margin at the sides, a small spot on the propleurae, a small spot 
on the mesopleurae below the anterior wings, a small spot above 
the tegulae, a large spot on the middle of the scutellum and a 
smaller one at each of the anterior angles, the postscutellum, two 
obligue bands on the median segment not reaching the base, a 
narrow transverse band near the apex of the first dorsal abdominal 
segment, a broad one on the second and third segments, narrowly 
interrupted on the third, a narrow one broadly interrupted in the 
middle on the fourth, the bands on the second and third segments 
continued on the ventral surface, a spot at the apex of the first 
ventral segment and a line on the femora beneath yellow; spines of 
the tibiae and tarsi testaceous. Wings hyaline, faintly tinged with 
fuscous, a dark fuscous cloud in the radial cell; nervures black. 
Length 12 mm. 
9. Mandibles falcate, acute at the apex. Head shining, micro- 
scopically punctured, more strongly above the base of the antennae 
and at the posterior angles, with a longitudinal frontal sulcus, as 
long as the breadth anteriorly, half as broad again anteriorly as- 
posteriorly, a large and very deep depression on the vertex half as 
broad again as long and touching the posterior margin of the head.
