30 THE DIPTERA-BRACHYCBRA OF TASMANIA, 



broad, finely banded, and having the fourth posterior 

 cell open. 



Nine species have been described as belonging to this 

 genus, six of these being from Australia, two from South 

 Africa, and one from South America. Of the Australian 

 species, however, E. terminalis, Walk., is the same as E. 

 variabilis, Macq., and one or two of the other species are 

 not, I think, correctly referred to this genus. E. rufipet, 

 Krdb., I consider to be more nearly related to Phycus. 

 The specimen from which von Krobcr took his descrip- 

 tion seems to have had the third antennal joint want- 

 ing ; a specimen in my possession shows this to be almost 

 the same as in the species for which he founded the genus 

 To nogera, which has a venation similar to that of Ecti- 

 norrhynchus. These two genera I am unable to separate. 

 E. rufipes, however, in its venation, position of the anten- 

 nae, which are situated about the middle of the face ; legs 

 and shape and banding of the wings, agrees with Phyctu 

 and disagrees with Ectinorrhynchus, whilst the form of 

 the antenna? is intermediate between them, and its only 

 agreement with Ectinorrhynchus seems to lie with the 

 lengthened proboscis, which does not, I think, indicate 

 anv real affinity. 



In Tasmania two species are known to occur, both of 

 them being also found on the Australian mainland.
