Characters. — Eyes contiguous in the male, separated in the female; the wings 

 have a variable venation, in which the upper branch of the cubital vein is pre- 

 sent or obsolete, the first and second posterior veins may be stalked, or issue 

 from the discal cell from a point or independently; the third posterior vein is 

 obsolete; the transverse vein between the second and fourth posterior veins may 

 be incomplete, making the discal cell partly open, and in one ease which is 

 illustrated (Plate xxix., fig. 7) the second basal cell is also partly open by a 

 similarly incomplete cross-vein. In the male the posterior tarsi are thickened. 



Note. — Walkers type from Tasmania is evidently a male and is not ade- 

 quately enough described for its identity to be positively determined ; the only 

 species known from that State that appeai-s to approach Walker's description 

 was subsequently identified and described as Metoponia prisca, but the identifi- 

 cation is not a satisfactory one. 



Chiromyza vicina Bigot. 



Chiromyza vicina, Bigot, Ann. Soc. Ent. France, (5), ix., 1879, p. 200 (2).

Note. — The position of this species is open to doubt, but as it was described 

 from a female, it cannot belong to the genus Boreoides, and its colour does not 

 agree with the known species under the genus Metoponia. The inadequate de- 

 scription reads like that of a typical female Chiromyza, and its habitat is queried 

 Australia.

Genus B R B o I D E s, n . gen . 



Boreomyia, Walker, MS. name. 



Definition. — T);e eyes are separated in both sexes; the antennae have "the 

 two basal joints of equal length and the third joint about twice the length of the 

 basal joints united in the male, and about the same length as the basal joints
