6 THE DIPTERA-BRACHYCERA OF TASMANIA, 



Tabanus similis, Macq. 



This species is only known from the type specimen 

 described by Macquart. It has been redescribed by Mis© 

 Ricardo (Ann. Mag. Nat. Hist., Nov. 1914, pp. 391-2), 

 whose description is here appended : — 



"A medium-sized yellowish species, with a narrow grey 

 median stripe on a wider darker stripe on the yellowish 

 abdomen. Antennae, palpi, and legs all yellowish. Length, 

 12i mm. 



"Face covered with ashy-grey tomentum. and some long 

 pale hairs. Beard white. Palpi pale yellow, with sparse 

 black pubescence, rather stout, ending in a point. Antennas 

 reddish yellow, the third joint (which is incomplete) with 

 a distinct tooth, the first two joints paler in colour, with 

 black pubescence. Forehead broad, about four times as 

 long as it is wide anteriorly, almost parallel ; frontal 

 callus large, square, not reaching eyes, reddish brown, with 

 a short lineal extension. Thorax drab in colour, with 

 traces of lighter tomentum. Scutcllum is similar. Abdo- 

 men (faded) warm buff-colour, with a broad median 

 mummy-brown stripe, on which appears a narrow grey 

 tomentose stripe ; the apex and sides are also mummy- 

 brown ; underside very similar, but no stripes are visible. 

 Legs reddish yellow. Wings clear, stigma yellow ; no 

 appendix present." 



This species should be easy to recognize by the absence 

 of a recurrent veinlet (or appendix) to the cubital fork, 

 in conjunction with the striped abdomen and light 

 colouration. 



Tabanus limbatinkrvis, Macq. 



A very large rod-brown species, with all the wing-veins 

 suffused with brown, and the first posterior cell closed. 



Length. Female, 20 nun. 



Miss Ricardo redescribes Macquart's type as follows: — 

 Palpi yellow with blaek pubescence, fairly stout through- 

 out, their Length, ending in an obtuse point. Antenna 

 reddish, black ;'t apex, with a well-defined tooth. Fore 

 head about eight times as long as it is broad, parallel; 

 frontal callus oblong, chestnut red. reaching eves, with a 

 Ion.' lineal extension. Eyes apparently bare. Thorax 

 (denuded) reddish with darker stripes. Abdomen reddish 

 brown, the dorsal white spots very indistinct owing to 

 denudation. Legs described by Macquart as black; the 

 tibia? yellow, the anterior and posterior pairs black at 

 apices "
