projecting. 
Belongs to Bingham's Section F [Fauna of Brit. India , T, 472) and

hyaline towards their base. 33 
Ccelioxys sulcispina , sp. nov. 
Black, the face, lower part of front broadly at the eyes, the lower 
three-fourths of the outer orbits, a small tuft in the middle of the meso- 
notum at the base, the part at the base of tegulse, a small patch behind 
them, 2 transverse tufts on the base of scutellum, the mesopleurse and 
mesosternum, the upper and lower part of metapleurge densely, the 
central sparsely, patches, narrowed inwardly, on the sides of the abdo¬ 
minal segments and continuous lines on the ventral of snow white pube¬ 
scence ; wings to the 2nd cubital cellule in front, to the 2nd recurrent 
nervure, hyaline, the rest fuseous, tinged with violaceous, the 1st cubital 
cellule and the greater part of the space between the recurrent nervures 
lighter in tint than the apical part, the nervures black. Apex of scutel¬ 
lum broadly rounded, the centre with a small rounded incision, the 
sides project into stout teeth, broad at the base, narrowed towards the apex, 
which is rounded, the sides are margined with a stout keel, the outer 
keel straight and commencing at the mesonotum, the inner shorter and 
rounded. Metanotal area semicircular, opaque, its base with a stout 
keel down the basal half in the centre, the base with a short striated 
border. Apical abdominal segment with 8 teeth, 2 short basal, 4 upper

punctures followed by a curved line of punctures in a shallow furrow, 
on the apex is a regular row of furrows, with some scattered ones before 
it in a curve, the 3rd is irregularly punctured, almost smooth near 
the base and apex, its apex and that of the 4th with a regular row 
of small punctures in a shallow furrow. Ventral surface with the
