REVISIONARY CLASSIFICATION OF RUTILIINI 65 
basal depression of calypter). Calyptrae not or only extremely faintly infuscate, 
basal part of upper calypter not unusually opaque white. Mesonotum with very 
broad bold continuous black sublateral vittae : : R. cryptica sp. n. (p. 65) 
— 6 genitalia otherwise shaped, surstylus without such tooth-like process and cerci 
either with tips bent forwards or backwards (Text-figs 72 & 73). Lower calypter 
with surface hairing mainly confined to basal depression and area adjacent to 
suprasquamal ridge. Calyptrae distinctly infuscate on at least the apical half, 
the basal half of the upper calypter unusually opaque white (the white colour very 
conspicuous to naked eye on side view of fly and strongly contrasting with the 
smoky lower calypter). Sublateral dark vittae of mesonotum either bold, 
broad and continuous or evanescent on scutum and broken at the suture . : 14 
14 6 genitalia with surstyli and cerci as in Text-fig. 73; surstylus with blunt antero- 
median projection and the cerci is profile very strongly recurved at their apices. 
Sublateral black vittae of mesonotum very broad, bold and continuous (no 
exceptions seen) . : ‘ . R. decora 
— 6 genitalia with surstyli and cerci as in Texte fig. 72: suratylus simple, without 
trace of prominence on its anterior edge, and cerci rather straight for most of their 
length but with the extreme tips bent distinctly forwards. Sublateral black 
vittae of mesonotum sometimes very broad, bold and continuous (especially in 
specimens from southern part of range) but usually fine and inconspicuous, 
evanescent on scutum and broken at transverse suture in Queensland specimens 
R. splendida 
15 Mesonotum dark bluish green to deep blue-violet, with the darker vittae very 
inconspicuous to naked eye (pair of lighter blwe lines sometimes present on 
prescutum). Surstylus of $ genitalia in profile as in Text-fig. 79, not deeply 
concave on its anterior edge. White aati of thoracic dorsum very 
inconspicuous to naked eye . ; R. caeruleata 
— Mesonotum pale brassy green with the four black! vittae vexy boldly marked. 
Surstylus of $ genitalia in profile rather deeply concave on anterior edge and 
strongly acuminate on apical half (Text-fig. 82). White pollinosity of thoracic dor- 
sum conspicuous to naked eye on prescutum anteriorly between the vittae, on 
humeral callus and on supra-alar area of scutum - ; : R. transversa 
Rutilia (Chrysorutilia) cryptica sp. n. 
(Text-fig. 74) 
6. Head. Ground colour mainly yellow-orange to reddish orange on parafrontals and 
interfrontal area, genal dilations with some slight metallic golden green reflections in some 
lights; pollinosity mainly bright yellow, thinner on parafrontals than on parafacials, but 
pollinosity of postorbits silvery white over dark ground colour; upper occiput dark metallic 
green; parafrontals with a little dark brown colouring just below vertex. Parafrontal and 
most of parafacial hair black or brownish black; genal, postbuccal and lower parafacial hair 
yellow to golden orange; occipital hair yellowish white. Vertex 0:21-0:24 of head-width (0-22 
in holotype). Frontal setae very fine, mostly hair-like, lowermost ones crossing at tips. Gena 
048-061 of eye-height (0-56 in holotype). Parafacial very wide, about 4-0 times as wide as 
third antennal segment, completely haired. Antennae reddish orange on first two segments 
and base of third, remainder of third segment suffused with darker reddish brown to brown 
colouring; antennae falling short of epistome by about their own length; third segment about 
2-1 times as long as second segment. Palpi yellow. Thorax. Dorsum golden green to viola- 
ceous blue with four very broad bold black vittae and blackish side-margins, the submedian 
pair of vittae stopping on scutum just beyond transverse suture, the sublateral black vittae 
continuous to hind margin of scutum and neither broken nor constricted at transverse suture; 
white pollinosity present over humeral calli, anteriorly on prescutum over the metallic areas 
between the pairs of black vittae, and on supra-alar spots, the pollinosity only conspicuous in
