This curious species is more robust than the generality of the 
insects of this singular genus. The head of the male has the sides 
rather curved and rugose, but in the female they are straight, 
forming with the part in front of the eyes an elongated cone; in 
the latter sox it is more rugose than in the male. The antennse of 
both sexes arc 9-jointed * : they are slightly thickened in the 
middle, the tip being slenderest; they are inserted in the under¬ 
side of the head between the front part of the eyes. The prothorax 
is narrower than the head, its narrowest part being before the 
place of insertion of the fore-feet; it is transversely rugose, and has 
the hinder portion nearly quadrate. The meso- and meta-thorax are 
swollen into a rounded hump, much broader than the rest of the 
body in the male, the abdomen in that sex being narrowed. The 
specimens before me have, however, been taken out of spirits, and 
are slirunk in the base of the latter part, so tliat I cannot speak with 
certainty on its form, or as to the shape of the meso- and meta-thorax 
in the female. The feet are comparatively robust, and the ungues 
are vei-y much dilated at the base, being furnished with an append¬ 
age almost as large as the pulvilli; the posterior femora are striated. 
I do not perceive in this species the difference in the number of the 
abdominal segments of the opposite sexes pointed out by M. 
Brulld; on the contrary, in both I find the same typical struc¬ 
ture, namely, seven basal segments of equal size, both on the 
dorsal and ventral surface, followed by two very short arcs, cut off 
obliquely at the sides on the dorsal surface, representing the 8th 
and 9th dorsal segments, whilst the 8th ventral arc is dilated into 
rotumlatoaulennisgracillimis, prothorace longissimo (Jong. unc. If) angusto latcribus senulatis; 
tegminibus et alts abdomen baud tegentibiis, Ulis pallidis griseo et fusco parum variis nubila 
fusca versus bfisin, venisque nigro strigatis ; alis hyalinU, costa maculisque nubUaqne versus 
basin brunneis; ccrcis analibus latis foliaceis, pedibns 4 posticis brevibus femoribus fere ad 
apicera S-foliatis tibiisquo ante medium supra parum foliatis. Long. corp. unc. 4f. Habitat 
in India orientali. In Mus. Ashmol. Oxon. et D. Hope. 
♦ Drs. Klug and Bnrmeister described the antenna; of the males of Proscopia as 6-, and those 
of the females as 7-jointed. M. Brulle describes the antennae of both sexes as 8-jointcd.
