antenna; black, slightly piceous beneath ; abdomen luteous, with only 

 the borders of the sheaths of the Baws below (the extremities of 

 which are visible above) black; the four front femora blue-black ; 

 front tibiae and tarsi whitish : four bind tarsi blackish, hind femora 

 and four hind tibiae luteous in the middle, and blue-black at I 

 extremities. Wings hyaline, with yellowish nervures inwards the 

 base; stigma large, piceous, with an oblique shade beneath. 



Described from the type in the Banksian collection, which is a 

 female in very good preservation. 



There are five specimens from Hudson's Baj in the British 

 Museum, which 1 am inclined to regard for the present a- variel 

 of this species. The i "lour of the antenna;, tibia?, and tarsi varies 

 from black or brown to yellowish, and in all at least the lasl two 

 segments of the abdomen are black. The only male closely reseml 

 the type of //. analis; but the body is ratlin- 1 and the wii 



are yellowish hyaline, with a shade below the stigma, which is nearly 

 obliterated in the type by tho dark colour of the wings.
