This species is at once distinguished by its short bi- 

 tuberculated mesonotum, and short broad tcgmina very 

 strongly elevated between the base and middle, and the 

 numerous minute spines on the front parts of the body. 

 The head is rounded, very gibbose ; eyes very prominent ; 

 hinder part of the crown armed with several rows of mi- 

 nute spines. The antenna; are short ; the joints slender, 

 short, and very numerous ; they are dark brown, annulated 

 with buff, the anuuli being near together towards the base. 

 The pronotum has the anterior lateral angles acute and 

 porrected, and the disc is furnished with a few acute gra- 

 nules. The mesothorax is not twice the length of the pro- 

 thorax ; it is widened behind, especially in the female, and 

 is furnished with numerous small tubercular spines, the disc 

 being armed with two elevated granulose tubercles a little 

 in advance of the middle. In the male the mesothorax is 

 comparatively more elongated than in the female. The 

 metathorax is longer than the mesothorax (being nearly 

 double its length in the female). The tegmina are nearly 

 square, with the angles rounded (those of the male being 

 rather longer than those of the female) ; the elevation of 

 the carina is very strongly raised and rounded, especially 

 in the female ; the veins are pale buff and finely reticulated. 

 The wings are large and brown, with the longitudinal veins 

 rather darker ; the costal area is mottled with black, green, 

 and obscure buff; the chief longitudinal vein is simple in 

 the male, but furcate in the female. The legs are short 

 (comparatively longer in the male), slender, and simple ; 

 the anterior femora very slightly sinuated at the base. The 

 abdomen of the male is slender, linear, and clavate at the 



extremity, the eighth segment being much the widest, and 

 the ninth short and nearly straight at its extremity, with 

 the sides rounded off ; the anal styles are rather thick, por- 

 rected, curved, and obtuse at the tips ; the three terminal 

 ventral segments are considerably swollen, and scarcely ex- 

 tend beyond the base of the ninth dorsal segment. The 

 abdomen of the female is gradually narrowed ; the three 

 terminal dorsal segments carinated ; the ovipositor is 

 scarcely swollen, and extends to about the middle of the 

 ninth dorsal segment.

The female of this beautiful species is unique in the Col- 

 lection of Mr. Westermann of Copenhagen, a gentleman 

 who possesses one of the most beautiful collections of in- 

 sects in existence, a large portion of which was collected 

 by himself in Asia and Africa. It is closely allied to the 

 female of N. Medora (PI. XXVII. fig. 1), but differs in 

 the smooth anterior portions of the body, short legs, and 

 tessellated wings. The body is comparatively robust, espe- 

 cially in the region of the metathorax ; it is smooth, green, 

 and opake. The head obovate ; eyes very prominent; 

 ocelli obsolete. Antenuse very slender, of moderate length, 

 and brown ; hind part of head very convex, unarmed, the 

 fore part luteo-fuscous. The prothorax is short. The meso- 

 thorax subcorneal ; it is swollen above in the middle into two 

 raised lobes terminating in points ; it and the prothorax are 

 obscure green, with a slender transverse sanguineous mem- 

 brane in front of each. The tegmina are broad, flat, with
