20 . E. W. Ferguson : 



Wings, hyaline, veins and stigma black; appendix present^ 

 always short, sometimes rudimentary. 



£ Eyes contiguous, very densely hairy, facets apparently uni- 

 form in size. Antennae with third joint less expanded at base,. 

 first and second joints very hirsute. 



Palpi yellowish brown, second joint oatshaped, densely pubes- 

 cent. 



Thorax similar to 2. Abdomen much more strongly nar- 

 rowed to apex, black sides of first and second segments reddish 

 brown, clothing as in $ . # 



Legs and wings as in ? . 



The female differs from T. anteccdens female in the wider 

 front, which is also more hirsute, the basal antennial joints are 

 also much more hirsute. In general it is darker in colouration 

 than T. antecedcns, of which it may represent a mountain race. 



Hab. : — Cradle Mountain, Tasmania (G. H. Hardy, Jan., 

 1917), l& f 7 $?. Two females from Mount Wellington and 

 one female from Maria Island apparently belong also to this 

 species, but differ in having the second abdominal segment red- 

 dish brown towards sides, with lighter anterior margin (in T. lati- 

 frons the anterior margin of second segment is dark greyish), 

 the other segmentations also are obscure reddish grey, instead 

 of dark grey. 



In some specimens the first and second joints of antennae are 

 black. A further long series of this species from Cradle Moun- 

 tain, collected by Messrs. A. M. Lea and H. J. Carter, is in the 

 South Australian Museum collection. Types presented to Aus- 

 tralian Museum, Sydney, by Mr. G. H. Hardy.

 tum, and with scattered black pubescence, a few white hairs at
