greatly developed and bisected front coxe, the subulate 
abdomen of the female with the last segments ovipositor-like, 
are as in the South-American forms of Chiromyza, in which 
there is also a great difference of size in the sexes *. 
It is important to notice that this first Stratiomyiid with 
vestigial wings is so advanced in wing-reduction, being nearly 
apterous and with the posterior part of the thorax undeveloped. 
It seems to be not rare in New South Wales and Victoria, 
the times of appearance being February, March, and May ; 
most specimens have been found in the mountains. 
In my opinion the Australian species of Chiromyza belong 
to a genus different from the true South-American one, the 
third longitudinal vein being typically forked (even if 
Mr. Hardy has shown the variability of this character) in 
Australian species, while it is typically simple in the American 
ones. In this case the name Soreoides can be used for the 
Australian Chiromyza’s, even for those with normally winged 
females. The apterous condition of the female sex only is 
not of generic value, as shown, for example, by the genus 
Tipula. 
In a recent paper by Dr, G. Enderlein (“Ueber die 
phyletisch alteren Stratiomyidensubfamilien,” in Mitteil. 
Zoolog. Mus. Berlin, x. 1921, pp. 153-214) a new genus 
Archimyza was erected for what seems to be the species 
described and figured by Hardy under the name of Chiromyza 
australis, Macquart. 
In comparing the two Tasmanian specimens before me with 
the figures and descriptions of the type-species subulatus, I 
have found some differences of great value, and it seems 
better to separate them as a new form, although on p. 541-of 
his paper Mr. Hardy says:—“ Specimens from ‘Tasmania 
taken on the summit of Mt. Wellington, and one taken by 
Mr. C. E. Cole near Bellerive, Hobart, undoubtedly belong 
to this species, but unfortunately they are not available for 
study at the time of writing this paper.” 
Boreoides tasmaniensis, sp. n., 2. (See figure.) 
Type-female and an additional specimen of same sex in the 
South Australian Museum from Hobart, Tasmania (Lea). 
Length of body 16-17 mm. 
Agreeing with Hardy’s description and figure of subulatus 
female, but differing in the following points :— 
(a) The third antennal joint has the annulation very 
distinct and deep, being divided into three parts. 
* Several pairs of Chiromyza fuscana, Wied., from Paraguay in my 
collection, taken im copula by Mr. Schrottky, measure 8-9 mm. in length 
in the males and 15-17 mm. in the females.
