trocerus. Bingham does not appear to have been actually acquainted 
with the species, for he, Lc ., only copies Smith’s description. I have a 6 
from Bombay, which agrees with Smith’s description of ornatus, except 
that it is not an dncistrocerus. I give here a description of both sexes 
of the Dehra species. 
$ Ferruginous, a broad oblique line over each antenna, about one- 
half longer than wide and united below by a narrower black line, a 
large spot covering the ocelli, more developed below than above them, 
narrowed gradually from the bottom to the top, the bottom transverse, 
except for a shallow incision in the middle, the occiput except above, 
more than the lower half of the occiput, a large mark on the basal 
half of the mesonotum, dilated laterally at the base, the apex gradually 
slightly narrowed to a rounded point, a squarish mark on either side 
of the apex, the edges of the scutellum and post-scutellum, the base of 
the propleurse, the base of the mesopleurse, the mark becoming widened 
below, squarish mark on the upper apical half, the base of the 2nd, 3rd 
and 4th abdominal segments, their apices more narrowly, a mark 
narrowed towards the apex, on the 2nd ventral segment and a line 
bordering the apex of post-scutellum and going down the centre of meta- 
notum, black. Legs coloured like the body, the base of 4 front femora 
and the hinder to near the apex, black. W ings yello wish hyaline, clear in 
tint behind, the radial cellule clouded. The puncturation on the head 
and thorax is strong and close, the post-scutellum more rugosely punctured 
than the scutellum, its apex above raised, crenulated, forming a segment 
of a circle. Sides of metanotum broadly rounded. First abdominal 
segment large, cup-shaped, the 2nd longer than it is wide at the apex. 
The $ is similarly coloured except that the clypeus, mandibles, except 
at the edges, a triangular mark on the front, continued as a short line 
between the antennse and a line on the lower part of the eye incision 
are bright lemon-yellow. The clypeum in the ? is longer than wide, 
closely distinctly punctured, its apex depressed, the sides forming shining 
reddish teeth; in the & the clypeus is wider compared with the width 
less closely punctured and there is a rounded incision on the apex; the 
legs bear less black. No doubt the black markings vary in size and shape.
