notum darker than the pleura, especially in the middle ; 
closely punctured, thickly covered with depressed fulvous 
pubescence. Scutellum pyramidal, the top shining, sparsely 
covered with large punctures and clothed with Jong fuscous 
hair ; the keels broad, extending from the base of the depres- 
sion to the middle behind, becoming narrower as they do so; 
below the keels the scutellum is closely punctured. Post- 
scutellum not much depressed at the base, stoutly longitudinally 
striated. The base of the median segment is obliquely de- 
pressed in the middle, irregularly rugose, the bottom smooth 
and shining; there are only the two central aree—the basal 
is slightly narrowed towards the apex and irregularly marked 
with stout keels, the apical area is narrowed at the base and 
stoutly irregularly striolated; the sides are stoutly carinate, 
except at the base, where the keels are somewhat indistinct ; 
the tooth very stout and prominent. ‘The propleure strongly 
punctured, especially behind, the lower partsobscurely striated, 
and with a stout keel behind the central depression. Meso- 
pleure strongly punctured; under the wings is a large pro- 
jection, roundly narrowed at the base and apex; the basal 
part of the metapleure strongly punctured, bordered at the 
top with a stout keel; the apex is coarsely, rugosely, irregu- 
larly reticulated. The anterior coxe slightly, the posterior 
coarsely, punctured. Areolet oblique; the first transverse 
cubital nervure is straight, oblique, the second more curved ; 
they unite at the top; the recurrent nervure is received 
shortly beyond the middle; the transverse basal nervure is 
almost interstitial. Petiole smooth and shining; the sides 
tuberculate at the spiracles; the apical half of the dilated 
part laterally depressed, the depression becoming gradually 
wider towards the apex. ‘The second and following segments 
are closely punctured, the third and following segments infus- 
cated; the gastrocceli large, deep, the base smooth, the apex 
aciculated, the outer edge obscurely striated. 
LAGENESTA, gen. nov. 
Antenne stout, dilated beyond the middle. Labrum 
largely projecting. Apex of clypeus transverse. Mandibles 
bidentate, the apical tooth the larger. Scutellum flat, its 
sides not carinate. Median segment without arex, all the 
keels being obliterated. Areolet large, five-sided, wide at 
the top. Legs stout, the tarsi spinose. Abdomen with 
seven segments, neither punctured nor striated; the ventral 
fold distinct on the second and third segments, less distinct on 
the fourth and fifth.
