The male is very slender and cylindrical, of a greenish- 

 black colour ; the abdomen and antennae black. The 

 head short and wide ; eyes large. Antennae very long, 

 black ; basal joint moderate-sized ; on the face between the 

 eyes is a circular depression. Mesothorax very slender, 

 and very finely granulated. Abdomen slender ; three ter- 

 minal joints short, bent upwards ; terminal joint slightly 

 notched at the tip ; anal styles short, obtuse ; three ter- 

 minal ventral segments swollen, extending to the extremity 

 of the abdomen, the terminal one emarginate at the tip. 

 Tegmina small, oval, with a moderately raised conical 

 tubercle near the base ; the inner edge, as well as a spot 

 near the base, obscure red. The wings have the costal 

 area blackish brown, varied with obscure paler greyish 

 spots, with a reddish tinge along the fore and inner margin ; 

 posterior area black, with a curved row of pale blue spots 

 near the apex. Under -side of the body and of the femora 

 tinged with green, except the metasternum, which is brick- 

 red. The tibiae slightly annulated with obscure paler 

 marks. 



The female is much larger and more robust. The head 

 and pro- and mesothorax greyish obscure, the latter finely 

 granulated, varied with blackish markings. The antennae 

 with a number of pale rings. The tegmina blackish, mot- 

 tled with greyish buff, as well as the costal area of the 



wings, the base of which is brown, tessellated towards the 

 middle with dirty-buff spots ; a large orange curved fascia 

 in the middle, followed by the curved row of blue spots as 

 in the male. The legs are alternately banded with buff and 

 blackish brown ; the three terminal segments of the abdo- 

 men are simple, with a curved upper outline. The opercu- 

 lum is but little swollen, and extends considerably beyond 

 the extremity of the abdomen ; it is acutely bifid at its tip, 

 and is accompanied within by two elongated horny append- 

 ages bifid at the tip, the upper apex acute and elongated.
