or testaceous. Legs ochreous-yellow ; the terminal joints of tarsi 

 almost imperceptibly infuscated. Wings almost hyaline (when 

 denuded) ; veins brownish, densely beset with long brown hairs. 



Bab.— Berowra, N.S.W. (Masters) ; Knapsack Gully, Blue 

 Mountains, N.S.W. (Skuse). August. 



Obs. — One specimen only was captured in each locality. The 

 specimens appear undoubtedly the two sexes of the same species. 



Genus 13. Tasiocera, gen.nov. 



Two sub-marginal cells ; four posterior cells ; discal cell present 

 or absent. Wings very cuneiformly narrowed towards the base, 

 pubescent along the veins 07ily. Second longitudinal vein originates 

 at an acute angle some distance before the middle of the anterior 

 margin ; sub-costal cross-vein very indistinct or none ; prcefurca 

 ends in the second sub-marginal cell, which is longer than the first ; 

 inner end of discal cell, and great cross-vein, not in one line with 

 the small cross- vein but much nearer to root of the wing (as in 

 Molophilus). Seventh longitudinal vein very short. Antennae 

 16-jointed, about twice the length of the entire body. Tibiae without 

 spurs at the tip ; ungues smooth on the under side ; empodia 

 distinct. Male forceps very hairy at the apex of the fleshy lobe, 

 terminated with horny appendages, toothed at the extremity 

 (PI. XXIV., fig. 55). 



The rostrum and palpi short. The antennae with one or more 

 very long cylindrical joints at the base of flagellum, the remainder 

 becoming more flasked-shaped, the terminal joint very small, more 

 or less ovate ; adorned with long verticillate hairs. The two joints 

 of the scapus are small, globose, or more cupuliform, equal in size. 

 In T. gracilicornis (PL xxiv., fig. 56) the flagellar joints more 

 quickly begin to appear flask-shaped, only the first joint being 

 cylindrical ; on this account the antennae are shorter than those of 

 T. tenuicornis. The first cylindrical joints and the basal portions 

 of all the following joints are about equal in width ; if anything, 

 the flask-shaped joints are slightly broader at their widest part
