A common sjtecies. As in some otiicr forms, this species 

 ranjjes into the niountain-districts of S.E. Australia.

This is very near A. viaculata, Gu6\\, hut clifTers in the 

 shape of the head anl pronolu:n in the fetnale, a^? well as in 

 the markings on the ni '(lian se^^int-nt in the male. It must 

 therefore be regarded a^ distinet, and not as a mere variety. 

 The males in Ajriomyia are very ditficult to separate when 

 the females are not available, owing to the want of good 

 structural differences, and until we have long series it is not 

 well to depend too much on colour-ilistinctions. Unfortu- 

 nately species of this group are not taken coupled nearly so 

 frerpu'ntly as most Thymiida3. 



Westwood does not give any locality for odyneroid'js, but 

 most of the specimens I have seen are Tasmanian. There 

 are also males in the British Museum from Adelaide, from 

 Jindabyne, N.S.W., 3000 ft., and from " ]\I..reton Bay." 

 All these have the third abscissa of the radius distiiicily longer 

 than in Tasmanian specimens.
