REVISIONARY CLASSIFICATION OF RUTILIINI gt 
hair pale yellow. Abdomen partly cupreous. Proclinate orbital setae in one pair 
only or none definitely developed. 1 + 1 sternopleural setae 
[Possibly the 2 of R. media] R. cupreiventris 
Basicosta blackish brown or at least dark brown anteriorly. Parafrontals showing 
metallic green colour at upper ends on to vertex. Sternopleuron with hair entirely 
black or black on upper part around and between the stp/ setae. Abdomen all 
golden green oremerald. Two pairs of strongly developed proclinate orbital setae. 
Normally 2 + 1 stpl setae (occasionally only 1 + 1) . 
Abdominal tergites 3 and 4 without discal setae and with entirely recumbent hair: 
T3 without median marginal setae Sternopleural hair all black Ground colour 
of lower parts of parafrontals reddish and not noticeably contrasting in any light 
with the reddish yellow ground colour of parafacials. Setae of the upper part 
of the postocular row short and straight . : : . : Undetermined sp. 
[Possibly the 2 of R. nigripes] 
Abdominal tergites 3 and 4 with some long fine irregular discal setae distinctly 
developed among the hair, the hair sub-erect medially on T3 and erect all over 
T4; T3 with a row of about four long fine median marginal setae. Sternopleural 
hair black around and between the stp setae but pale yellowish on mid part of 
sternopleuron. Ground colour of parafrontals blackish and in some lights con- 
trasting rather abruptly with reddish yellow ground colour of parafacials. Setae 
of the upper part of the postocular row rather amie and fine and curved slightly 
forwards. : é ; : } : E R. liris 
[Probably the ? of Vee ‘nines 
Hair of pleural regions and abdominal venter pale yellow. Hair of fore coxae 
mainly golden : : Undetermined sp. or spp. 
[Possibly g of R. fulviventris. 3 genitalia ‘souilar to R. nigripes. Specimens 
from Queensland have extremely narrow upper frons as in nigripes, measuring 
0:05-0:06 of head-width. Other specimens from Victoria have frons at narrowest 
from 0-065-0-080fhead-width. Queenslandspecimens belong to R.vuficornis sensu 
Enderlein, not Macquart. They may possibly be a colour polymorph of nigripes.] 
Hair of pleural regions and abdominal venter almost all black. Hair of fore coxae 
black (at most a few golden hairs at extreme base and apex) ; 
Ground colour of parafrontals entirely blackish. Very small species (length es mm) 
with exceptionally long fine bristling and oe 6 surstyli and cerci as in ae 
62 or Text-fig. 109 : 8 
Ground colour of parafrontals tawny reddish or brownish, at most only a little 
blackish at upper ends. Larger species (length 9:5-15 mm) with vestiture not 
exceptionally long and fine. ¢ surstyli and cerci of different shape (Text-figs 
60 & 61) a ‘ ‘ ‘ 9 
Ground colour of parafacials blackish ‘and concolorous with ey 6 surstyli 
and cerci as in Text-fig. 109, surstyli with sharp apical point and cerci sinuous in 
profile. rons at narrowest point distinctly wider than third antennal segment 
R. nigriceps 
Ground colour of parafacials yellow and rather sharply contrasting with the blackish 
parafrontals. 4 surstyli and cerci as in Text-fig. 62, surstyli rounded apically and 
cerci straight in profile. Frons at narrowest point ee lees in width to or very 
slightly narrower than third antennal segment . : : . R. minor 
Eyes exceptionally strongly approximated, interfrontal area almost completely 
obliterated at its upper end, frons at narrowest point only 0:05-0:06 of head-width. 
6 genitalia with free apical parts of cerci not much longer than the contiguous 
basal parts, and the outer margins of the bases of the cerci rounded (Text-fig. 61).
