Both sexes of this species are contained in the Royal 

 Museum at Berlin. The head is convex ; the mesothorax 

 granulose ; the median carina of the tegmina very strongly 

 and roundly raised between the base and middle of the 

 tegmina ; the wings extend to the end of the sixth segment 

 of the abdomen. The following are the proportions of the 

 female : —

The pale- ringed antenna? and the elegant contrast of the 

 two portions of the beautifully tinted wings distinguish 

 this species. The general colour is dull luteous, tinged 

 with green on the thorax, and with fulvous on the abdo- 

 men, which is glossy. The head is broad, with the eyes 

 very prominent, convex above, fine green, with a large yel- 

 low rounded spot between the eyes. The antennae are very 

 long and slender, blackish, with about five whitish annuli. 

 The metathorax is finely granulated. The tegmina are 

 small, subovate, rather strongly angulated near the middle ; 

 the base, and a spot between the base and the middle of 

 the inner margin, together with another spot beyond the 

 middle of the outer margin, pale. The wings are rosy pink ; 

 the costal area green, yellower at the base, with the veins 

 darker green, the principal vein not being furcate. The 

 abdomen is loug and slender ; the terminal segments con- 

 siderably swollen ; the ninth dorsal segment with an acute
