species are rather flattened in shape, never humpbacked or 

 conspicuously bristly, usually moderately pubescent, but 

 never with the dense funy pubescence of the Bomhylince. 

 In Tasmania three genera are known to occur. 



Table of the TasiiKinian Genera of Antlirncince. 



1. Wings with three submarginal cells. 2 

 Wings with only two submarginal cells. 3 



2. Antsnn?e with a distinct style. 



ExoPRosopA, Macq. 



3. Antennae without a distinct style. Anthrax, Scop. 

 Antennae with a style bearing an apical pencil of 



hairs. (Velvet-black species, with wings mostly 

 black). A R G Y R A M CE B A, Schin. 



It should be noted that although the species of Anthrax 

 have u'jually only two submarginal cells, yet varieties occur 

 in which three are present, or occasionally there may be 

 two on one wing and three on the other. In any case, 

 however, the species may be distinguished from those of 

 EToproiiopd by the want of any differentiated antennal 

 style. 



48. E X o p R o s o p A, Macq. 



{Trinaria, Muls. Argyro^piJa, Rond. Utteralonia, Rond. 



Defili ppia, Lioy. Eroptata, Coquill.) 



Third joint of antennae elongate-conical, with a fairly 

 long, clearly-differentiated, terminal style, ending in a 

 microscopic bristle, but withorft any apical pencil of hairs. 

 Proboscis short. Claws, of posterior tarsi with a basal 

 tooth. Wings with three submarginal cells; the four pos- 

 terior cells and the anal cell all open. 



Two species of Erojjrosopa have been described by Mac- 

 quart from Tasmania, neither of which is known to me, 

 and I am unable to say whether or not they are correctly 

 placed. The position of the second species (E . hicellata) is 

 particularly doubtful, owing to its possessing only two sub- 

 marginal cells. The following are Macquart's descrip- 

 tions. 



ExOPROSOPA OBLIQUEFASCIATA, Macq. 



Black ; head with white pubescence ; abdomen banded 

 with white, the sides spotted with brown ; wings hyaline, 

 with the base, ccsta, and two obli pie stripes brown. 



Length. 12 mm. 



Hab. 'Tasmania."
