MR. HENRY WALTER BATES ON PHASMIDÆ. 351 
From Serville's description of his mutilated specimen. of N. vittata (Orthopt. p. 254), 
the present seems closely allied to that species; it differs, however, in the opake roseate- 
tawny hue of the posterior area of the wings. The species belongs to the section of the 
genus indicated (in the description of our N. cephalotes) as distinguished by the great 
size of the head and short filiform shape of the antenne. The body is slender and fili- 
form, the head being the broadest part; the colour is pale luteous, but probably green in 
life, some traces of this colour being seen on the head; and there is a black line extend- 
ing on each side from the eye to the base of the mesothorax. The antennæ are only one- 
third the length of the body, and filiform, the base not being much thicker than the 
remaining part; there are two elevated lines along each side of the mesonotum, and the 
surface is faintly warty. The apical dorsal segment of the abdomen has its terminal 
angles each produced into a short curved lobe; and the anal styles project a short di- 
stance beyond them, and are clavate in shape. The tegmina are narrow, and obtusely 
truncated at the apex ; their central elevation is but slightly prominent, and their colour, 
together with that of the anterior field of the wings, is brown, with a straw-coloured 
vitta extending along the middle from base to apex; the posterior field is of a uniform 
tawny-pink hue and opake. The legs are rather short (except the anterior pair) ; and the 
intermediate and posterior femora have a row of minute spines along their under surface, 
the anterior pair having only a few similar spines near their tips.

Resembles much N. Palinurus, Westw. (Cat. Phasm. pl. x1. f. 6), but differs in colo- 
ration. Cylindrical, robust, tawny-coloured, smooth. Head very large and of equal 
thickness, oblong, slightly narrowed behind the eyes, unarmed, reddish-tawny, with five 
black stripes—namely, one central, not reaching the level of the eyes, one on each side 
from the eye to the occiput, and another quite lateral, abbreviated. Antenne short, 
filiform, basal joint not enlarged. Thorax and abdomen dingy-tawny, with a black stripe 
on each side, extending from the prothorax to the last abdominal segment. Abdomen 
cylindrical; the eighth dorsal segment the largest of all, and much longer than the 
seventh ; apical segment one-third the length of the eighth, and narrowed to the tip, in 
the middle of which there is a smail but distinct notch. Operculum linear, not convex, 
and not reaching the apex of abdomen ; anal styles exserted, brown, compressed. Tegmina 
narrow and elongate, central prominence slightly marked, brown, with a central straw- 
coloured vitta; costal field of the wings of the same colour; posterior field dingy-white,
