Type of D. lanatus, a male from Van Diemen's Land 

 (/. Brijnce). 



Type of D. thalpius, a male from Perth, W. Australia 

 (G. Clift07i). 



Type of D. agave, a male from Swan River, W. Australia. 



Also a series of males and females from S. Australia, Tas-

Length 9 lines. ^ ? . 



Palpi black, with black hairs. Face black ; moustache 

 and beard golden yellow, the first reaching the antennae. 

 Forehead black, with black bairs. Antennae black ; the first 

 joint a little elongated, with black hairs below. Thorax 

 black, with black hairs ; sides with greyish-yellow tomentum 

 and whitish hairs. Abdomen narrow, 6 lines long, black,

 whitish hairs ; anterior femora black, testaceous at the apex, 

 posterior ones black, the posterior half below testaceous ; 

 tibiae black at apex ; anterior tibiae with no spines ; tarsi 

 black. Wings clear, a little yellowish ; apex slightly 

 brownish. 



From New South Wales. Coll. M. Fairmaire and M. Bigot. 

 One specimen in the coll. of Marquis Spinola comes from 

 Sydney Island, Oceania.
