In Brit. ]Mus. Coll. specimens from Victoria {Lea) and 

 Hunter River, New S. Wales. 



A very large, dull, blackish-brown species, 30-40 mm. iu 

 length. Wings in males very much dilated on fore border. 



Face with distinct tubercle, the moustache composed of 

 black and yellowish hairs. Antenna have the first joint 

 twice as long as the second (not equal in length as v. d. 

 Wulp states). Abdomen with yellowish-grey tomentum and. 

 very short fulvous pubescence on dorsum, sides with longer 

 yellowish hairs. Male genitalia rather large, black. Female 

 ovipositor small, the eighth segment distinct. Legs stout, 

 red ; base of femora, knees, and tarsi black, the numerous 

 bristles are black. Wings much dilated in male, not usually 

 so in females, but the submarginal cell is rilled as in male, 

 hyaline, with yellowish-red veins ; posterior branch of third 

 vein strongly curved ; second posterior ceil broad at base, 

 bulging into the first one ; the third nearly as wide as the 

 second, the fourth and anal cell closed, the small transverse 

 vein beyond the middle of discal cell. 



AsiLUS in sensu stricto. 

 Linn., Syst. Nat. ed. x. pp. 605, 227 (1758). 



This genus, in the narrowest sense, is usually defined as 

 comprising large bright-coloured species ; the abdomen at 

 sides near the segmentations without any bristles ; dorsum 

 "with short appressed pubescence ; ovipositor conical, not 

 compressed. The following species appear to belong to this 

 genus, but Asilus inglorius and discutiens differ from the 

 other species by the presence of thick tufts of hair on the 

 basal segments of abdomen, on dorsum, though not reaching 

 the median line ; they approach Pamponerus iu this character, 

 but the facial tubercle and non-contrasted colouring of wings 

 prevent their inclusion in that genus.
