posed of black dots, passing backwards, curving outward, end near 

 the base of the triangular brown area; between this line and the 

 triangular area is a light brown oval area; segments 7-10 almost 

 entirely blackish brown dorsally, but 7 and 8 have triangular white 

 areas on sides, and 9 a slight indication only; segment 10 has the 

 sides of dorsum white. Ventrally segment 1 is dark brown, and 

 remainder white with brown m.arkings; segment 2 has two brown 

 spots; 3 with two smaller brown spots and a slightly reddish area 

 at anterior margin in median line; on 4 and 5 the brown spots be- 

 come smaller and the reddish areas larger; on segment 6 the reddish 

 area is elongated to the posterior margin; on 7 and 8 there is a 

 median longitudinal brown line, thickened about the middle, and 

 two dots of unequal sizes on each side of it; segment 10 brown, 

 except for a lateral white streak on each side. Forceps white and 

 4-jointed. Setae white, with brown joints, and minutely pubescent. 

 Fore legs brown; femur with a light area near distal end, next to 

 which is a dark brown band; tarsal joints 1, 2 and 3 about equal in 

 length, 4 slightly shorter, and 5 about half the length of 4th. 

 Hind legs lighter in colour than fore; a brown band on femur in 

 distal half; tibia with a brown band about middle; tarsus light in 

 colour, but brown at joints; joint between tibia and tarsus 1 not 

 distinct. Claws unlike. Wings with brown neuration; costal cross 

 veins and others toward base of wing margined more or less with 

 brown; a slight brown cloud in apical costal area; a heavy brown 

 cloud at bulla; often a small cloud at bifurcation of median vein; 

 cubitus 2 strongly bent at base ; hind wing with a large brown cloud 

 at base. 



Female imago : 



Quite similar to male. 



Nymph: (PI. VI. figs. 8, 9.) 



Measurements — Body 15 mm.; setae 5 mm. The two nymphs 

 collected proved to be a male and female, both mature, but, un- 

 fortunately, both died when just about to transform. On this 

 account it is difficult to describe the colour pattern, as the body of 

 the subimago shows through the nymph skin. 



Head vertical; body curved. Posterior lateral margins of ab- 

 dominal segments 1-9 produced into spines. Dorsal colour pattern
