The metathorax is about two-thirds of the length of the 

 mesothorax, oblong convex, smooth, with the lateral margin 

 on each side armed with a similar row of small black spines ; 

 the six basal abdominal segments are large, smooth, convex, 

 and destitute of spines, with an acute lateral margin ; the 

 three terminal segments are small and narrowed, the eighth 

 segment being the shortest, the ninth gradually attenuated 

 and rounded behind, and with the two short caudal styles 

 scarcely visible at its sides. The operculum is very long 

 and boat-shaped, extending the length of the three termi- 

 nal dorsal segments ; beyond the extremity of the abdomen 

 it is furnished within with two compressed, narrow, sabre- 

 shaped appendages, as loug as the operculum itself The 

 legs are moderately long, the thighs strongly, and the under 

 edge of the tibise less strongly serrated. 



A female specimen in the National Museum, smaller 

 than the usual-sized individuals, has the sides of the meso- 

 thorax almost parallel.

 The only known male of this species is a mutilated in- 



dividual, which I have examined and sketched, from the 

 Leyden Collection. The type of the female in the Berlin 

 Museum is a gigantic insect, of which I have given the 

 proportions above. The sixth ventral segment has a small 

 spine in the middle of its hind margin ; the terminal dorsal 

 segment is truncated or rather slightly trilobed, and the 

 operculum is boat-sha])ed, and extends nearly to the extre- 

 mity of the last dorsal segment. The anal styles are very 

 minute. 



In general form this female bears a close resemblance to 

 the female figured in my PL VI. fig. 5.

The male is long and very slender, destitute of spines, 

 except on the legs. The head is much broader than the 

 prothorax, oval, very convex in its hinder part, the middle 

 of which is elevated into two minute conical tubercles of 

 unequal size. The mesothorax is long, smooth, ami of 

 equal width, except at the hmd part ; it is of the same 

 length as the metathorax. The tegmina are obovate, 

 much constricted towards the base, the middle being raised 

 into a large rounded tubercle ; they are dirty ashy brown, 

 with the base of the outer margin luteous. The wings are 

 large, but narrow, very sHghtly tinged with brown, and 

 with darker brown longitudinal veins. The costal area is 

 pale greenish brown, pale luteous along the base of the 

 outer margin ; the chief vein is furcate in both wings at 

 half an inch from the base ; the transverse veinlets are very 

 niunerous, straight, and distinct. The abdomen is long, 

 cylindrical, and smooth ; the seventh segment gradually 

 widened, and the ninth deejdy slit at its extremity ; the
