206 THE DIPTERA-BRACHYCERA OF TASMANIA, 



ExoPROSOPA BiCELL\TA, Macq. 

 Black, with red tomentum. Wings> brown with hyaline 

 spots; number of submarginal cells two. 

 Length. Male, 11 mm. 

 Hab. "Tasmania." 



49. Anthrax, Scop. (Fig. 38.) 



Antennae without any clearly-differentiated style ; wings 

 with two submarginal cells ; the bifurcation of the radial 

 and cubital veins takes place at a right angle, almost in a 

 line with the median cross-vein. 



Fig. 38. Wing of Anthrax minor. 



Head large, globular, as wide as the thorax. Proboscis 

 short, not in the least projecting. Antennae very small 

 and short, widely separated at the base, the first joint 

 cylindrical, the second cup-shaped, the third an elongated 

 bulb-shape, without any differentiated style, the apex ter- 

 minated by a micro'scopic bristle. Eyes separated in both 

 sexes, but more widely in the female than in the male. 

 Thorax rather large, flattened, and pubescent; scutellum 

 with or without marginal bristles. Abdomen longer than 

 the thorax, sometimes conspicuously flattened. Legs slen- 

 der, the tibiae with small, weak bristles. Wings with nor- 

 mally two submarginal cells, but varieties occur in which 

 three are present, or there may be three on one wing and 

 only two on the other; radial vein curved upwards, but 

 never strongly looped as in the Tjomatincd; upper branch 

 of cubital fork much curved upwards ; posterior cells four 

 in number, which are all open, as is also the anal cell. 

 The wings in Australian species are usually'- hyaline, with 

 the costal margin brown, but they may be quite hyaline, 

 or entirely suffused with brown. 



A large number of Australian species have been described 

 under the genus Antlirur, but many of these do' not really 

 belong here, but should be placed in the genera Hypera- 

 lon'ia, ExoproRojia, Argyramaclia, and Comptima. Of the 

 true species of Anthrax, eight of the sixteen Australian 

 species at present known occur in Tasmania.
