of tlie tectum, on each side, another ridge starts and runs backward 

 at an angle, so that the two together form a V-shaped marking, the 

 point of which is rounded, and lies within an indented semicircle in 

 the anterior margin of the abdomen. The elevated markings on 

 the tectum form transverse wavy lines. There is a strong chitinous 

 projection from the side of the cephalothorax between the second 

 and third pairs of legs. The stigmata are near the lateral margin 

 between the first and second pairs of legs. The stigmatic hairs 

 are short, and consist of a small globular head, on a stout filiform 

 peduncle. There are two pairs of short, thick hairs on the dorsal 

 surface of the cephalothorax. 



The coxfe of the first two pairs of legs are hidden beneath the 

 body. The trochanters of the same pairs are large and long, but 

 suddenly become small, and turn almost at right angles near their 

 insertion into the coxae. The coxae of the third and fourth pairs of 

 legs are rounded and conspicuous. The second and fourth joints 

 are the longest in all the legs, the third joint being the smallest. 

 The first three joints in each leg are covered with irregular raised 

 markings. The tarsi have a few fine hairs round the claws, which 

 are very heterodactyle. There are three short, thick hairs on the 

 fourth joint of each leg of the first two pairs, and a few other 

 similar hairs on the different joints of the legs. All these hairs are 

 very caducous. 



The abdomen is elliptical, slightly pointed posteriorly, and 

 slightly truncated anteriorly ; it is indented between the insertion 

 of the third pair of legs and the stigma, and the anterior margin is 

 cut out in rather more than a semicircle. This indentation receives 

 the point of the V-shaped ridge on the cephalothorax; and at the 

 side of it the anterior margin of the abdomen is attached to the 

 upper surface of the tectum. There are about ten short, thick 

 hairs round the hind margin of the abdomen, also very caducous. 



On the ventral surface the genital plates form almost a square, 

 and are far forward. The anal plates are large, elliptical, and touch 

 the posterior margin. 



Nymph. 



The colour of this curious nymph is dull opaque brown, often 

 with a shade of dark olive green in the brown. It is so broad and 

 flat in general shape as to give the effect of having been 

 flattened out, and it is thickly covered with wrinkles and ridges all 

 over. 



The cephalotliorax is flat, long in proportion to the abdomen, 

 but not in proportion to its breadth, conical, but sharply excavated 

 at the edge, for the insertion of the first pair of legs. The base of 

 the cephalothorax is narrower than the anterior margin of the 

 abdomen, and the second pair of legs are inserted in the angles thus
