The unique specimen of this species in the National Col- 

 lection is a female, which had been preserved in spirits, so 

 that its colour, now a uniform dull luteous buff, was pro- 

 bably green when alive. It is elongated, with a very slender 

 mesothorax. The head is oval, rather flattened above, with 

 a small impression on each side behind the eyes. The 

 antennae are slender (broken off about half an inch from 

 the base). The prothorax small. The mesothorax slender, 

 cylindrical, granulated. The tegmina small, oval, with a 

 moderately strongly angulated carina. The wings of mo- 

 derate size ; the costal area darker than the hinder area, 

 which is almost colourless. The abdomen is long, and con- 

 siderably broader than the mesothorax, with the middle 

 joints broadest. The operculum is as long as the three 

 terminal dorsal segments, and the two anal styles are slightly 

 porrected. The legs are moderately long, slender, and 

 destitute of spines.

The female of this species (the male not having yet been 

 received) is distinguished by its elongated mesothorax and 

 abdomen and its short legs, the anterior femora being di- 

 lated along the lateral margins. It is slender, destitute of 

 spines, the mesonotum alone being finely tuberculated. 

 The head is rather wider than the prothorax, subconvex, 

 pale at the sides, with a slender curved dark line extending 

 backwards from the eyes. The antennae are of moderate 

 length, very slender, obscure brown, with numerous pale 

 rings ; basal joints pale. The mesothorax is about three 

 times the length of the prothorax. The tegmina are short, 

 subovate, glaucous, reticulated with the dark veins. The 

 wings are subhyaline, being only very slightly stained with 

 brown ; the costal area is darker, redder brown, wnth small 

 darker clouds, and with dark spots along the mid-vein, 

 which is furcate. The legs are short, setose, simple, dirty 

 buff, with darker rings and marks ; the anterior femora 

 dilated along the edges. The abdomen is very long and 

 slender ; the eighth and ninth segments short. The oper- 

 culum is rather small, reaching to the middle of the ninth 

 dorsal segment ; the anal styles short and very broad.

 three terminal segments of the abdomen seen sideways. 



A variety of this species, from Ceylon, is in the collec- 

 tion of R. Templeton, Esq., in which the wings are less 

 iridescent, and the two branches of the median vein of the 

 costal area are not united at the tip of the wings.
