A slender and delicate-looking species, of a uniform pallid greyish brown colour, 
faintly marbled with olive-brown ; the membrane of the wings transparent and tinged 
with a milky hue. The body and legs are unarmed ; the apical dorsal segment in the male 
is triangularly emarginated at the apex, and the edge of the emargination has a row of 
small tubercles. The operculum of the female is simple, and reaches barely to the 
tip of the abdomen ; the anal styles are short and linear, but slightly tapering to the 
apex.

Elongate, cylindrical, and moderately slender; the body, antennze, legs, tegmina, and 
anterior area of the wings pale grass-green ; posterior area of the wings very pale 
greenish yellow, uniform. The head is oblong, plane above, and not at all narrowed behind 
the eyes, the latter moderately prominent. The mesothorax is much elongated, cylin- 
drical and smooth. The legs are unarmed. The operculum is boat-shaped, and reaches 
the dorsal tip of the abdomen; the anal styles are small and obtuse. The tegmina are 
elongated and tapering to the tip, and the central prominence forms a moderately 
elevated flexuous ridge; an obscure pale line runs down the middle of each tegmen. 
The wings are produced and acute at the apex.

A large and rather robust species, with moderately elongated but linear mesothorax, 
and oblong quadrate, plane-crowned head. The upper side of the head, prothorax, and 
mesothorax is opake, pallid ochraceous; but the under surface, in striking contrast, E 
of a blackish-brown hue; the broadish, obliquely and obtusely truncated tegmina. 
the anterior area of the wings offer a similar contrast of colours, the tegmina being 
dark-brown, with the inner margin irregularly bordered with chalky-ochraceous, and u | 
costal area of the wings being light yellowish, with a broad dark-brown costal. strip? |
