strongly marked with black-brown tessellations along the 

 transverse veins ; the costal area is red-brovrn, with the 

 numerous transverse veinlets whitish ; the central vein is 

 furcate near the base. The legs of the male are long and 

 slender, shorter and more robust in the female ; the ante- 

 rior pair nearly simple, but the four hinder with the lower j 

 angles (especially of the femora) finely serrated. The ab- 

 domen of the male is long and slender ; the terminal ven- 

 tral segment short and much swollen ; the terminal dorsal 

 segment contracted at the base, swollen at the sides, and 

 furcate at the extremity, with minute teeth at the inner 

 edges of the furcation. The ovipositor of the female is 

 boat-shaped and compressed, followed by two compressed 

 porrected anal styles about as long as the preceding joint.

I have only seen the male of this species, which is very 

 long, slender, and cylindrical, entirely of a luteous pale 

 brown colour (the specimen had, however, been preserved in 

 spirits of wine). The head is rather large and subdepressed ; 

 the eyes very large, as well as the three ocelli. The antennse 

 are short and thick, 23-jointed, the joints narrowed at the 

 base, and setose. The mesothorax is long, armed with four 

 pairs of short thick spines. The tegmina are elongate- 

 ovate ; the median carina moderately elevated . The wings 

 are large, stained along tlie outer margin with darker brown; 

 the costal area darker, especially along the basal half, 

 with the median vein furcate near the base. The abdo- 

 men is very long and slender ; the last joint truncate, with 

 the truncation curved ; the anal styles as long as the three 



terminal joints, flattened, and slightly pointed at the tip. 

 The legs are of moderate length and serrated, the anterior 

 tibise being simple ; the four hind tibiae with a bispinose 

 foliaceous lobe near the base on the upper edge.

I at first thought it possible that the insect here figured 

 might be the male of Cyphoerania Goliath, but the arrange- 

 ment of the spines of the hind legs and mesosternum will 

 scarcely allow of such an idea.

Body large, slender in the males, thick and cylindrical 

 in the females. Head flat, gibbose behind. Ocelli 3. An- 

 tennae moderately long ; those of the males one-third 

 longer than those of the females, pilose, and 23-jointed, — of 

 the females shorter, glabrous, and 26-jointed. Thorax short, 

 pyramidal ; mesothorax scarcely twice the length of the 

 prothorax, gradually widening behind, spinose. Meta- 

 thorax rather longer than the mesothorax, broad and ob- 

 long. Abdomen with the ovipositor of the females strongly 

 cymbiform, carinated beneath and pointed at the tip ; anal 

 styles very long, narrow in both sexes ; terminal segment in 

 the males truncate at the tip and biuucinate beneath. Teg-
