844 TABANIDAE FROM CAMDEN HAVEN DISTRICT, 



reaching the eyes on each side, resting on subeallus, with a 

 moderately long lineal extension to beyond middle. Eyes bare. 



Thorax light brown with three darker stripes, darker portions 

 clothed with brownish, the lighter with grey tomentum, with 

 moderately thick dark semierect hairs anteriorly and posteriorly, 

 and with fine scattered white silky hairs; pleurae grey with long 

 pubescence, brown above, white below and posteriorly. Scu- 

 tellum light brown. 



Abdomen light brown (Mars brown) becoming darker to apex, 

 with greyish segmentations, moderately densely clothed with 

 black depressed pubescence, pale creamy hairs on segmentations, 

 thickest at sides and in centre where it forms a series of more or 

 less distinct spots from 2nd to 6th segments. Venter yellowish 

 brown with lighter segmentations, clothed with whitish pubes- 

 cence, thickest on segmentations. 



Legs yellowish, anterior femora with light hairs below, dark 

 above; other femora mainly whitish hairs, tibiae with black hairs. 



Wings clear, veins brown, stigma conspicuous, short appendix 

 present . 



In appearance this species strongly resembles T. circumdatus 

 but will be readily distinguished by the bare eyes. It is perhaps 

 closest to T. eidvoldensis, but may be readily distinguished by 

 the more reddish thorax and the light coloured forelegs. Taylor 

 has placed T. eidvoldensis in Group vii., but it seems to me 

 that its natural position is with T. kewensis in Group ix. The 

 whole question, however, of the grouping of our Australian 

 species of Tdbanus requires revision. Specimens were taken 

 from February 20th to March 6th, but it was always a rare 

 species . 



Group x. 



Tabanus cyaneus Wied.

This fine metallic blue species was never very common. Spe- 

 cimens were obtained between December 10th and March 7th. 

 The eyes are distinctly red when alive. Two of the specimens 

 are decidedly larger than the others, but in other respects iden- 

 tical .
