Bathypogon hruchijpterus, Macquart. 

 Proctacanthus postica, Walker. 



This species is erroneously placed in Kertesz's catalogue 

 under Astyhim, a genus formed by Rondani for a species 

 from Venezuela with no terminal bristle or style to the third 

 joint of antennpe. 



Type ( ? ) from New S. Wales seen by me in Paris 

 Museum, 12. 4. 11. 



In Brit. Mus, Coll.: type of Pructacanthus posticn, Walker, 

 from Melbourne (Mr. Baby's coll.), a female from New S. 

 Wales (Saunders coll.), and another from Maclcay, Queens- 

 land (G. Turner) (1894). In Mr. French's coll. a female 

 from Victoria. 



Macquart's description is as follows : — 

 Black. Abdomen ashy grey below. Femora and tibia} 

 red below. 



Length 8 lines. ? . 



Face and forehead yellowish grey ; moustache reaching to 

 the base of antennae, yellowish white ; the upper hairs black. 

 Beard and hairs of palpi white. Hind part of head with 

 yellow hairs. Antennnc black. Thorax black; stripes on side 

 and scutellum with grey tomentum. Abdomen black, with 

 scattered small yellow hairs; sides and belly ashy grey. 

 Legs : femora and tibise red ; with a black stripe above, 

 which is wider on the posterior ones ; posterior legs black ; 

 tarsi black, with yellow hairs, which are also present on the 

 tibise. Wings rather short, slightly yellowish ; brownish at

 oblique posterior vein, the posterior vein of fork of third

 New South Wales. 



The antenrxB have a short terminal style. Moustache 

 black above, theii yellow. In the specimens before me there 

 are no black hairs on upper part of moustache. The small 

 cross-vein of iving is situated slightly beyond the middle of 

 the discal cell. 



Length of specimens 18-20 mm. 



Walker's type is probably a specimen of this species ; the 

 type is in very bad preservation.
