This species, of which I have only seen a single speci- 

 men of the male, approaches N. JEsalus, of which it might 

 at first be supposed to be the opposite sex ; the armature of 

 the head and legs seems, however, sufficiently to disprove 

 this relationship. The head is nearly ovate ; the eyes mode- 

 rately prominent ; the ocelli wanting ; the inner margin of 

 each eye is armed with two small spines, and the hind part 

 of the crown of the head is raised into a rugose tubercle 

 armed in front with minute spines. The mesothorax is 

 rather short and subrugose. The tegmina are nearly square, 

 with the costa elevated into a strong crest, rounded in front. 

 The wings are large and pale, with the costal area darker 

 and clouded. The abdomen is elongated, as wide as the 

 mesothorax ; the fourth, fifth and sixth segments a little 

 dilated at a short distance from the base of each ; the seventh 

 and eighth short, and rather wider than the preceding ; the 

 ninth subquadrate, rather constricted in the middle on each 

 side, with the apical angles rounded off, and the hind 

 margin emarginate in the middle. The anal styles are 

 short, obtuse, and not exposed ; the three terminal ventral 

 segments are short, only extending to the base of the ninth 

 dorsal segment ; they are moderately swollen, the eighth 

 being very short and transverse. The legs are rather short 

 and robust ; the four posterior femora witli two or three mi- 

 nute spines on the under side near the tips ; the basal joint 

 of the tarsi is not longer than the three following joints.

This species is shorter and more robust, especially in 

 the mesothorax, with shorter legs than many of the allied 

 species. The head is short, with the eyes prominent ; it 

 is destitute of ocelli, and is of a luteous colour ; the crown 

 is rugose and armed with minute spines, as is also the pro- 

 thorax. The antennae extend to the middle of the meta- 

 thorax ; they are luteous, with the tips of the alternate 

 joints black. The mesothorax is robust and rugose, being 

 covered with numerous spinulose granules. The tegmina 

 are subquadrate, with the carina strongly elevated into an 

 oblong lobe ; they are luteous buff, with the base, outer 

 margin, and tips blackish. The wings are pale, and slightly 

 tinged with rosy brown ; the costal area is blackish in front, 

 luteous behind, the base pale luteous with a black patch. 

 The abdomen is more slender than the metathorax, gra- 

 dually thickened to the fifth and sixth segments ; the three 

 terminal short and attenuated, the eighth being very short ; 

 the anal styles are short and obtuse, and the operculum is 

 not quite the length of the abdomen. The fore legs are 

 wanting in the unique female in the National Collection ; 

 the four posterior are short and simple, with the tips of 

 the tibiae black ; the basal joint of the tarsi is not longer 

 than the three following joints.

I have only seen a single female specimen of this spe- 

 cies in the National Collection. It is long and narrow, 

 smooth, except the mesothorax, which has a row of gra- 

 nules arranged on each side of the slender, slightly raised 

 median line ; it is brown, with the pro- and mesonotum 

 tinged with luteous, the legs luteous buff, and the abdo- 

 men dark brown, with the anal styles black. The head is 

 of moderate size, destitute of ocelli, with the hind portion 

 raised into two small tubercles. The mesothorax is of 

 moderate length, not longer than the metathorax. The teg- 

 mina are small and subquadrate, with the carina moderately 

 elevated near the base. The wings are large, very pale
