towards apex and tarsi dark ; femora with lont;- pale pubescence, posterior 

 tibiae with heavy fringe of white hairs along outer side; wings whitish, veins 

 pale brown, appendix present. Long.: 13 mm.; width of head, 5 mm.; wing. 

 12 mm. 



Hab. S.A., Pt. Lincoln, Denial Bay. 



A distinct species from any known to me. and separable from most of the 

 described species by the posterior tibiae being fringed with white hairs. T. 

 robiislus Taylor has similar white hairs on the posterior tibiae, but judging from 

 the description has distinct thoracic ornamentation ; the curious meal-like tomen- 

 tum on the abdomen is also characteristic. There is another species before me 

 doubtfully identified as T. acutipalpis Macq., which has a white fringe of hairs, 

 but it differs widely in general appearance, thoracic markings and size. The 

 wings, though quite transparent, ha\-e a distinctly white appearance. Two 

 other specimens in the collection perhaps represent a variety of this species. 



9 Face, cheeks, and subcallus vellnwish brown with pale creamy tomentum 

 and ])ubescence; palpi light yellow; antennae with two first joints and base of 

 third reddish brown. Forehead yellowish Iirown witli light creamy tomentum 

 and dark pubescence, callus pale vellnwish brown without extension. Eyes very 

 densely hairy. Thorax similar luit more evidently clothed with decumbent 

 golden pubescence. .Abdomen with moderately dense decumbent black pubes- 

 cence and pale creamy pubescence along the segmentations and forming a series 

 of median spots on the second to sixth segments. Legs as in type but posterior 

 tibial fringe with dark hairs intermingled with the white. Wings as in type. 

 Long. : 15 mm. 



Hab. S.A. (A. P. Burgess), Alt. Pleasant, in scrub (J- G. O. Tepper, 

 S.I 1.86). 



The Mt. Pleasant specimen is more abraded than the other, and in general 

 appearance approximates closer to the type, but the black hairs predominate in 

 the tibial fringe. Larger series may shew that these specimens are entitled to 

 specific rank. 



A specimen from Perth. Western .Xustralia, appears to belong to the same 

 species as the var. ?. it differs in being somewhat darker, particularly the sides of 

 the second abdominal segment.
