TACHINIDAE OF AUSTRALIA 61 



appears best to treat Eipe and Campylocheta as separate genera, but Frivaldskia 

 ought probably to be treated as a synonym of Campylocheta. 



The principal characters of the tribe are as follows. Eyes haired; facial ridges strongly 

 setose (Text-fig. 33); face deeply sunken but epistome not projecting; vibrissae level with 

 epistomal margin; antennal axis well above level of eye middle; head receding below, much 

 shorter at vibrissal axis than at antennal axis; ocellar setae very strong and directed outwards 

 and backwards; inner vertical setae parallel; parafacials bare, or haired on upper half only; 

 proboscis very short, palpi well developed; presternum and prosternal membrane bare; 

 propleuron pale haired ; humeral setae four (basal row of three and one set forwards) ; 2—3 + 3 

 dc setae; pre-alar seta very small; 1 + 3 ia setae; two or three stpl setae; scutellum with three 

 pairs of very strong marginal setae (basuls, subapicals and horizontal crossed apicals), subapicals 

 extremely wide apart, occasionally a weak fourth pair of setae present between the subapicals 

 and apicals; scutellum without definite discal setae; pteropleural seta absent; infrasquamal 

 hairs present or absent; fore coxa bare on inner anterior surface; mid tibia with a v seta; 

 hind tibia without pv apical seta, usually with three strong d preapicals; hind coxa bare 

 posterodorsally; wing with several strong setulae dorsally on node, veins usually otherwise 

 bare above (some American forms with R l setulose); R s open or closed in wing margin 

 (occasionally very short -petiolate) ; bend of vein M forming very obtuse angle, without 

 appendix, remote from wing margin ; distance on vein M from bend to m-cu at least equal 

 to and usually greater than that from r-m to m-cu; apical section of Cu l longer than m-cu; 

 second costal sector very short and haired ventrally; calyptrae normal; abdomen with Ti + 2 

 excavate to, or almost to, its hind margin; Ti + 2 without median marginal setae; intermediate 

 abdominal tergites with discal setae; T5 with a complete transverse row of very strong erect 

 discal setae around the upper surface; sternites concealed; male hypopygium very conspicuous, 

 T7 + 8 at least partially exposed, cerci enormous and curved forwards (slightly hook-like) 

 in profile. 



Finally here it should be noted that the spellings Campylochaeta and 

 Campylochaetini in the literature are erroneous, as Campylocheta Rondani is the 

 correct original spelling in nomenclature. 



Tribe VORIINI 



Most of the members of this tribe have a very characteristic head facies and 

 wing venation and it is usually possible to recognize the voriines easily once one 

 of the genera has been seen in a named collection; often one glance at the wing 

 is sufficient for reliable tribal placement. The notable features of the head and 

 wing alluded to are listed in detail later. The tribe is nearly cosmopolitan, and 

 includes four genera in New Zealand; in this tribe there is therefore, perhaps, some 

 faunal connection between Australia and New Zealand. Three genera are known 

 from Australia, all of which occur also outside the area: Voria occurs widely in the 

 New World and throughout most of the Old World, Afrovoria occurs in Africa, 

 India and Western Australia, and Hyleorus occurs in New Guinea as well as Australia. 

 When the Voriini are studied in more detail it will almost certainly be concluded 

 that Hyleorus is widespread also in the Ethiopian Region and Eurasia (including 

 Japan) as there appears to be little doubt that the genus Steiniomyia Townsend 

 (synonyms Neuroplagia Townsend and Afroplagia Curran) is identical with Hyleorus; 

 comparison of material of several species of Steiniomyia (including elata Meigen, 

 the type-species) with Hyleorus from New Guinea and Australia has shown no
