2. TABANUS 363 



bristly hairs on its anterior margin shorter tlian usual. Pubescence on 

 the front coxa3 long and brownisli yellow ; that on the femora usually blackish, 

 fairly long and abundant behind the front pair and beneath the middle pair, 

 • but i-ather more abundant and conspicuous beneath the hind pair, but that 

 on the middle pair sometimes and that on the front pair rarely mainly 

 pale ; middle tibiae ciliate but not very conspicuously so ; hind tibiae with a 

 rather coarse and rather dense dorsal ciliation, and with a more dense though 

 less coarse ciliation beneath, but with no specially long antcro-ventral ciliation 

 as in T. tropicus ; there are some "touch-hairs" beneath the basal joint of 

 the front tarsi and at the tips of the next three joints, and also some at 

 the tip and two or three scattered ones on the underside of the apical third 

 of the front tibi«. Pulvilli brownish orange ; claws obscurely brownish red at 

 the base but black at the tip. 



Wings slightly greyish, rather darkened along the subcostal vein and 

 this darkening widens out about its tip so as to form a long narrow incon- 

 spicuous stigma. Squamse glassy pale brownish orange, with thick and browner 

 margins, and with pale almost microscopical fringes except for the fairly 

 conspicuous yellow tuft at the frenal angle of the alar pair. Halteres dull 

 blackish with the top of the knob brown, or brown with the top of the 

 knob brownish orange. 



9 . Greyer than the male, and usually without any brownish orange markings on 

 the (juadrately ended abdomen. 



Frontal stripe yellowish ashy grey or pale brownish grey, only slightly 

 contracted below as it is almost parallel-sided and hardly four times as long as 

 its width at narrowest part ; lower callus shining black, rather tiunsverse and 

 extended quite to the eyes, and almost always connected not narrowly to an 

 elongate ovate shining black middle callus ; upper part of frons indistinctly 

 darkened round the ocellar space ; ocellar space only slightly elevated, 

 brownish red ; pubescence on the frons (when seen sideways) only short and 

 slight, yellowish all down the sides and front part but black on the upper 

 middle part right up to the ocelli ; aljove the ocelli there are very few 

 curved short black hairs but no obviously longer hairs there or anywhere 

 about the vertex ; side-cheeks with shorter less dense mainly yellowish white 

 pubescence, but with a few black hairs on the upper part and sonre indistinct 

 (sometimes very indistinct) short ones down the sides near the eyes, and 

 these short hairs indistinctly extend all along under the eyes to just 

 the lower part of the back of the head ; pubescence on the lower part of the 

 jowls and all about the mouth yellowish white ; back of the eyes with a 

 distinct ec^ual narrow bare light grey rim, and behind this rim with a short 

 blackish yellow ciliation which becomes a little longer and rather less 

 blackish on the upper half but does not become in any way evidently longer 

 about the vertex ; frontal triangle (separated by a furrow from the cheeks) 

 with apparently a blackish ground colour but obscured by light grey or 

 yellowish grey dust ; antennal pits dusty orange. Palpi with the second 

 joint dull yellow or pale yellow, rarely orange, with numei'ous short black 

 bristles which are often absent about the base and which are usually longer 

 and not so dense as in T. diMinguendus and not at all obscuring the ground 

 colour, but in some specimens of apparently this species these black bristles 

 are more numerous and are shorter • this second joint is bare on its inner 

 side, and is moderately dilated soon after its base and then gradually tapers 

 to a rather blunt point, and is nearly four times as long as its width at its 

 broadest part ; basal joint also yellow and bearing long ])ale pubescence 

 though sometimes with some still longer pale hairs beneath about the tip. 

 Eyes clothed with short pale pubescence on the front part, but the pubescence 

 not extending to the upper or hind ])arts and becoming very sparse on the lower 

 part ; Colonel Yerbury made notes of the colour of the eyes in three females 

 taken at Nethy Bridge on July 9, 1905, the first specimen had two bands across 

 the eyes of which the lower one was very indistinct, the second specimen had 

 one band, and the third specimen two distinct bands, but Brauer described the 

 eyes as emerald green with three linear carmine red bands, of which the middle 

 one often failed to reach the hindmargin, and with the upper and lower margins 

 emerald green. Antennae almost as in the male, there being no long pubescence
