Its occiput is convex with five lightly marked lines, the median 

 somewhat costate. The prothorax is about 4 lines long, and 3 

 broad, very slightly wider at the base than at the apex, and divided 

 by a transverse and longitudinal sulcus into four sections, the 

 posterior ones largest ; in the upper half of the thorax there ai'e 

 four tubercles, two close tojthe head, the others near the transverse 

 sulcus ; in the lower half there are also four tubercles placed two 

 each side of the median line close to the base ; there is also a deep 

 transverse ioipression across the apex of the prothorax, and there 

 seems to have been a good deal of yellow colouring over the whole 

 of its upper surface. The mesothorax is about 12 lines long, as 

 wide as the prothorax, of equal thickness throughout and armed 

 with strong spines over its whole surface. Beneath both meso and 

 metathorax are similarly armed. The tegmina are almost half the 

 length of the wings and of oval form ; there is an indistinct trace 

 of a lightish coloured band across them behind the middle. The 

 costal area of the wings is broad and of the same reddish-brown 

 hue as the tegmina, the hyaline portion is barred with bi'own. The 

 legs are all densely spinous. The abdomen is bulky and extends 

 more than an inch beyond the extremity of the wings.

This should perhaps be placed in a new genus. The specimen 

 (a male) is over six inches in length and appears of a uniform 

 brown colour, excepting on the head, which is yellowish. The 

 form is more slender than in 0. MaclayL The head is elevated on 

 the occiput into a bilobed rounded prominence ; the face is rather 

 inflexed like that of a Blatta ; the pro-thorax is rather narrower 

 than the head and about 3 lines in length ; the meso-thorax is 

 about 10 lines in length, smooth and cylindrical. The tegmina 

 are about one-third the length of the wings, with an oblique 

 yellow fascia extending from the upper margin near the base to 

 the middle of the inferior margin. The wings are four-fifths of 

 the length of the abdomen, and are of a uniform dingy brown. 

 The legs are moderately spinose ; the anterior tibise are singularly 

 contorted and twisted
