Long, slender, subcylindrical ; the female more robust, 

 with the hind part of the mesothorax and the metathorax 

 dilated. The general colour of the head and thorax is ful- 

 vous or luteous, varied vpith dark brown markings. The 

 head is unarmed, and furnished with two small round 

 tubercles between the eyes, which appear to be developed 

 into ocelli in the male ; the hind part of the head is marked 

 with eight more or less distinct dark lines. The antennae 

 are very long and slender (one-fourth longer than the entire 

 insect in the male) ; the basal articulations are luteous ; at 

 the distance of half an inch from the base the joints be- 

 come very short, a single joint at equal distances apart 

 (about a quarter of an inch) being pale at its base, and 

 there being also a ring of white near the tip. The pro- 

 thorax is marked with two rather angulatcd lines down the 

 middle. The mesothorax is marked with several dark 

 patches, especially one on each side near the tegmina ; its 

 disc is covered with small luteous granules. The tegmina 

 are subquadrate, with the carina moderately elevated in the 

 middle into a rounded lobe ; they are black, with the 

 lateral margin and the fine reticulated veins green. The 



wings are long and rather narrow ; the costal area is green, 

 with the veins (both longitudinal and transverse) paler, 

 marked with a number of dark brown clouds forming indi- 

 stinct fascise ; the chief longitudmal vein is simple. The 

 posterior area is brown, more or less strongly tinged with 

 rosy red. The legs are luteous buff, with dark brown 

 rings ; they are slender and simple, with the basal joint of 

 the tarsi long, and pale yellow, with the tip black. The 

 abdomen is brown, with the articulations paler ; that of the 

 male is very slender, with the three terminal segments 

 rather short and slightly swollen ; the last segment attenu- 

 ated and notched at the tip ; the three ventral segments are 

 moderately swollen, extending a little beyond the base of 

 the ninth dorsal segment. The terminal segments of the 

 female are simple, the operculum extending to half the 

 length of the ninth dorsal segment.

The original type of this species, described by Mr. G. R. 

 Gray, is preserved in the British Museum. The antennae 

 have the basal joints annulated with black. The tegmina 

 have a central spot and the curved carina pale yellow. The 

 costal area of the wings is pale green, with a line along the 

 middle and several small spots yellow. The mesothorax 

 has a fine central longitudinal entire carina, on each side 

 of which are rows of minute tubercles placed wide apart.
