hair and others black pleural hair (sometimes with pale hair on barette or ptero- 
pleuron), and the number of median marginal setae on abdominal T3 varies in 
different specimens (there is also sexual dimorphism in these setae which are often 
absent in males but always present in females). The strength of the parafacial 
hairing varies greatly amongst females. 
It may be useful to note the condition of some of these varying features in the 
primary types of elegans and zabirna in case it is later concluded that elegans is an 
admixture of species. In the holotype of elegans the legs are blackish brown with 
slightly more reddish tibiae, the pleural hair is black except for some golden hair on 
the lower pteropleuron and the barette, and the prosternum and prosternal membrane 
are strongly haired (the prosternum even bears one very long strong downwardly 
directed bristle on each side) ; in the lectotype of zabirna the legs are similar to elegans 
type, the pleural hair is also black but there are only a few pale hairs on the ptero- 
pleuron and all the barette hair is black, and the prosternum and prosternal mem- 
brane have a few strong hairs (but no definite bristle). The paralectotype specimen 
of zabirna is topotypic and unquestionably conspecific with the lectotype, but has 
the prosternum and prosternal membrane almost completely bare (one long recum- 
bent hair on one side of the membrane, no hair at all on the prosternum itself); 
otherwise it agrees with the lectotype. (Townsend, 1932 : 39, noted the two strong 
prosternal setae in the holotype of elegans, as ‘2 PST’, but his statement that the 
rest of the prosternum is bare is incorrect.) In the primary types of both elegans 
and zabirna the prosternal hair is black. The lectotype of versicolor could not be 
located for study during the present work. 
The specimen from Newdegate with male genitalia as in Text-fig. gt has mainly 
yellow pleural hairing (only mesopleural hair mainly black), has some long fine very 
pale yellowish hair on the prosternum, and has the legs entirely reddish yellow; the 
specimen from near Watheroo with male genitalia as in Text-fig. 92 has the pleural 
hair similar to that of the Newdegate specimen, but has the prosternum and 
prosternal membrane completely bare, and has the coxae and femora partly blackish- 
brown with the rest of the legs reddish. 
Macquart (1846) recorded the provenance of elegans, at the time of description, 
as ‘ile Sydney’ (New South Wales), and the holotype from Bigot’s collection bears 
a label by Austen recording the locality as Sydney, New South Wales; the same 
type-locality was indicated in my paper on Macquart’s Australian Tachinid types 
(Crosskey, 1971). It is now certain, however, beyond any real doubt that the type 
must have come from Western Australia: all later known material is from Western 
Australia, and it is here considered that Paramonov (1968 : 374) was right to regard 
Macquart’s stated provenance as a mistake and to accept Western Australia as 
being the true type-locality. 
Almost nothing is known of the early stages and host-relations of Chrysopasta. 
Malloch (1930 : 106) described the puparium from a specimen with its associated 
adult from Swan River, and stated that another specimen from this locality had a 
label reading ‘Rutilia sp. in nest of Termites, Eut. westaustraliensis’. It is extremely 
improbable that Chrysopasta has a termite host as the known hosts of Rutiliini are 
all coleopterous, and it should be assumed that there is no direct connection in the
