notch at its tip. The tegmina are elongate-ovate, with 

 an oblong tubercle in the middle. Wings chalybeate-brown, 

 with numerous luteous oval spots forming irregular fasciae ; 

 costal area ashy-brown ; the base with a black spot. Legs 

 of moderate length ; anterior tibiae with the lower edge 

 rather dilated, the upper with three small lobes ; fore tarsi 

 compressed, the basal joint cristate ; four hind femora 

 strongly curved, furnished near the base with two diver- 

 ging lobes ; tibiae towards the extremity with several small 

 lobes.

Body long, slender and cylindric, winged in both sexes. 

 Head rounded ; ocelli wanting. Mesothorax scarcely twice 

 the length of the pro thorax. Tegmina obsolete or minute, 

 spiniform or stipuliform. Wings in both sexes large, those 

 of the females smaller than those of the males. Legs 

 short, simple. Abdomen slender. Oviduct of the females 

 not extending beyond the extremity of the abdomen. 



Inhabit the Islands of the Eastern Ocean. 



The original type of this curious genus and following 

 species differ from the remainder in not possessing the 

 slightest rudiments of the anterior pair of alary organs, — 

 being, so far as I yet know, the only instances of such a 

 departure from the ordinary conditions of insect develop- 

 ment. In the other species the tegmina are represented by 

 two minute spines, or two small scales incurved at the 

 sides.

Hab. In Malacca (B. Wallace). In Mus. Saunders. 



Specimens of this species of large size have been col- 

 lected by Mr. Wallace in Malacca, which I at first con- 

 sidered sufficiently distinct to form a separate species. I 

 can, however, after more mature consideration, only regard 

 them as forming a local variety, in which the body is quite 

 smooth, the head broad, and the eyes large. The antennae 

 are long and slender, upwards of 70-jointed, the joints 

 beyond the middle becoming more and more indistinct, 

 except at intervals of four or five joints, which gives the 

 appearance of long compound joints. The head is pale 

 luteous, with seven longitudinal dark streaks on its hinder 

 portion, the middle ones being transversely united between 

 the eyes. The prothorax is square, the anterior angles 

 spiraculiferous, transversely impressed across the middle, 

 and marked with blackish stripes, two of which form a V 

 in the middle of the front half; the mesothorax is also con- 

 siderably varied with blackish, which colour leaves a pale 

 frontal hastate and two reuiform lateral patches of luteous. 

 The metathorax is nearly as long as the pro- and meso- 

 thorax united. The abdomen is long, ITarrow and convex 

 in the male, wider in the female, with a dark longitudinal 

 median stripe, having two larger oval and several smaller 

 dark spots on each side of it. The legs are moderately 

 long and simple, luteous-coloured ; the femora and tibia; 

 with the extremity and a fascia across the middle black ; 

 the tarsi black, except the pale basal joint. The wings 

 are brown; the costal area pale green, with numerous
