82 NOTES ON ATSTllALIAN r.0.MBYLllD.?3. 



SYSTROPIN^. 

 Genus Systropus, Wiedemann. 

 Note. — Amongrst White's manuscript there is the de- 

 scription of a species for which it was intended to give new 

 generic and specific names. I have seen in the Melbourne 

 Museum specimens of the same species and they are ciosely 

 allied to and cei'tainly cogencric with my Syi^tropns clavi- 

 femorata. White's description was based upon two male 

 specimens sent by Mr. F. P. Spry, and were from Belgrave 

 and Gippsland, Victoria. Names were not given in the 

 manuscript, and although White stated "Gen. nov. allied to 

 "Systropus," he did not give particulars of what he con- 

 sidered to be the characters of his proposed new genus 

 whereby it can be distinguished from Systropus. 



BOMBYLIIN^. 



White's manuseript. — .... (Here comes a key to the 

 genera of the Bomhylins sensu luto, which has already been 

 published by White in these proceedings) - 



"Great variation is shown in the amount of curvature 

 "of the radial vein, but this appears to be a specific char- 

 "acter only. I have examined all Walker's type species, ex- 

 "cept B. areolutns, but the following four species of Macquart 

 "are unknown to me, and I cannot at present place them: — 

 "Bombylms consohriuus, peveUlatus, pictipennis (should be 

 "easily identified by the markings of the wings), and tcnui- 

 "cornis, Mac(i. Of the two following, I have not the doscrip- 

 "tions: — B. (instraliunus and rubriventris, Bigot. 



Genus DisCHlSTUS, Loew. 



The fir.st posterior cell open; first basal cell much longer 

 than the second basal cell.
