260 XOTES ON AUSTRALIAN TABAN.IDAE, ii., 



greyish-yellow tomentum, rather densely covered with dark hairs with some 

 paler hairs intermingled; beard whitish. Palpi tawny, second joint rather short, 

 oval-shaped, rather densely clothed with mingled dark and light pubescence. 

 Antennae black as in 2. Eyes large, holoptic, bare, with facets rather small, 

 equal. Thorax as in S but with more conspicuous pubescence, the pale straw- 

 coloured hairs scantily present on anterior as well as posterior portion and more 

 evident around seutellum. Abdomen with first three segments more evidently 

 diluted with reddish-brown at the sides, pubescence more distinct. 



Dimensions: 2 holotype. Length, 14 mm.; wing, 13 mm.; width across eyes, 

 4.5 mm.; <S autotype, 15 mm. 



Range of variation: ? 14-16 mm. (5 specimens) ; c? 13-15 mm. (2 specimens). 



Holotype 9 and autotype c? presented to Australian Museum. 



Hab. — New South Wales: Blue Mountains. 



Specimens are under examination from the following localities : Leura, 2 

 2, January, 1920 (Dr. A. L. Maclean); Blackheath, 2 2, 12.2.22, 4.2.22 and 

 2 c?, 22.2".22 (E. W. Ferguson); Blue Mts. (no locality) 1 2, January, 1922 

 (Deuquet). A specimen of this species is also in the South Australian Museum 

 from Wentworth Falls. This specimen was commented upon by one of us (E. 

 W.F., under T. macquarti Eic.) in a paper on the Tabanidae in that Institution 

 (Records of South Australian Museum, Vol. 1, No. 4, 1921, p. 373). 



In general appearance the species approaches closely to T. alternatus (= 

 T. macqitarti Ric), but differs in the wing pattern which resembles that of T. 

 doddi Taylor, though less marked. From the latter species it differs in the 

 much shorter "tooth" on the base of the third antennal joint. 



The species can hardly be T. funebris Macq., from the description of which 

 it differs in size, palpi not black, and the absence of a recurrent appendix to 

 the third longitudinal vein.

A specimen of Walker's species was recently received by one of us (E.W.F.) 

 from the British Museum, and iDroved to be the same as T. obscurimaculatus 

 Taylor. 



A specimen of Taylor's species was also sent to the British Museum (G.F.H.) 

 and compared with the type of T. pvraepiositiis Walk.

Egg-masses were found at Magnetic Island, N.Q., (24th and 25th November) 

 on twigs and grass overhanging small pools in the sandy bed of a creek, which 

 had the appearance of those of the above species described in an earlier paper 

 (HiU, Bull. Ent. Res., xii.. 1921, p. 41). Three of these batches of eggs were 

 subsequently reared to the final larval stages and proved to be referable to the 

 above. The third batch produced larvae of a species not known to us in the 

 immature stages. The history of the two batches of eggs of T. aprepes is as 

 follows : — 



(a). This mass was found at 5 p.m. on 24th November on a flower-head 

 of Juncea, 5 inches above clean, wet sand at the margin of a small pool in 

 creek-bed. When found the eggs were creamy white, but at 7 p.m. a few de-
