Tabani(la3 of the Australian Region. 273 



proboscis. Antenna black, the first two joints with black 

 hairs ; the third joint in type is imperfect ; in the other 

 female the basal divisions are fairly distinct, the basal 

 division broad, forming a sliglit angle. Eyes bare. Fore- 

 head parallel, same colour as face, about five times as long 

 as it is l3road ; the frontal callus l)lackish, very narrow, con- 

 tinued nearly to the vertex, ending in a fine point. Ocelli 

 distinct. Thorax blackish, with two distinct grey tomentose 

 broad stripes, with appressed white and fulvous pubescence, 

 longer at sides and on posterior border. Scntellum covered 

 Avith grey tomentum, leaving a dark brown spot in the 

 middle, with fairly long white pubescence. Abdomen 

 blackish, the median spots triangular, large on the second, 

 third, and fourth segments, their apices not quite reaching 

 the anterior borders ; a narrow band of white hairs is con- 

 tinued from each spot to the side, where it broadens out 

 into a wider spot continued up the side of segment; sides 

 ■svith long white hairs ; puijescence on the grey spots white, 

 elsewhere black ; underside with white-haired bands, matching 

 those on the dorsum. Legs black, the pubescence on the 

 coxae and underside of femora white, elsewhere black. 

 Wings clear, tinged faintly with brown on the fore border, 

 more widely so towards the apex ; veins yellowish brown. 



The species bears a great resemblance in the shape of the 

 frontal callus and foreiiead and in the markings of the wings 

 to Fseudotubanus distinctus. 



PsEUDOPANGONiA, gen. nov. 



This genns is very distinct from any other genus known 

 to me in the Pangoninse in its general appearance and in the 

 form of the antennae, which have three joints as usual, but 

 the third joint has only four divisions. 



Antenn<B are small, situated on a rather protuberant 

 tubercle ; the first two joints short and stout, the second 

 siiorter than the first ; the third twice as long, composed of 

 four divisions, the first one being stout, conical, the re- 

 maining three very narrow, each about the length of the 

 basal joint. Fulpi are small and narrow, Probc^scis short. 

 Face short, nearly horizontal. Forehead narrow and furrowed. 

 Ocelli prominent on vertex. Abdomen large and flat. 

 Pubescence very scanty. Hind tibiae with one stout spine. 

 Wings large, longer than the abdomen ; all cells except the 

 anal one widely open ; no appendix.
