Two male specimens of tliis species from Mangalore, 

 Tasmania, 24. x. 1911 and Ifi. iii. 1913 (A. White). 



The characters lis.t('tl in the foregoing key will serve to 

 (listingnish this species from the next two, with which it 

 forms a group tliat differs from any in the genns known to 

 rae from any part of the world. The general hahitus of the 

 forms is very similar to that of small CalliphorirKB, hwi no 

 reliable characters are present that appear to justily their 

 separation from other Hcli/ifp. 



Helina irhitci, sp. n. 

 Male and female. — The largest of the three species and 

 quite robust. Colours as stated in key, the thorax very 

 conspicuously vittate. ^Viiigs hyaline.
