and slender, very shallowly and indistinetly punctured, the meso- 
pleurae coarsely but shallowly punctured. Abdomen slongate, flat- 
tened, very slender at the base, shining and very sparsely punctured, 
with pale fulvous pubescence on the sides; the first segment with 
a deep sulcus from the base to the middle, the seventh dorsal seg- 
ment deflexed and narrowly truncate at the apex, the hypopygium 
straight and narrow, scarcely projecting beyond the dorsal segment 
and very narrowly truncate at the apex. Maxillary palpi slender, 
the fourth and sixth joints the longest. The first recurrent nervure 
is received beyond the middle of the second cubital cell, the second 
at about one quarter from the base of the third cubital cell. 
Black; the mandibles, except at the apex, the apical half of the c]y- 
peus, the lobes of the interantennal prominence, the inner margin of the 
eyes, the lower half of the outer margin continued along the margin 
of the head and broadly interrupted on the vertex, a minute spot 
between the posterior ocelli and a short oblique line on each side 
on the vertex behind them, a vertical band on the propleurae, the 
posterior margin of the pronotum, the tegulae and a streak above 
them, which is sometimes interrupted forming two small spots, a 
quadrate spot on the mesonotum near the posterior margin, two 
minute spots close to the anterior margin touching the inner longi- 
tudinal furrows, a broad curved band on the mesopleurae, a large 
spot above the intermediate coxae, a spot on the centre of the scu- 
tellum and a smaller one at each of the anterior angles, a trans- 
verse band on the postscutellum with a small spot on each side, 
two curved bands on the median segment broadening and diverging 
from the base to the apex with a spot on each side at the base, 
the coxae beneath and the posterior coxae above bright yellow; the 
sides of the first abdominal segment, a broad band close to its apex, 
a large spot on each side of dorsal segments 2—5 and of ventral 
segments 2—4, a smaller spot on each side of the sixth dorsal seg- 
ment and a large one on each side of the seventh yellow suffused 
with light ferruginous; the apex of the first segment, the second, 
third and fourth segments above and beneath, the pygidium, tibiae.,
