abdomen viewed from behind. Mesonotum very dark blue-black or violaceous

Palpi and epistome black or brownish black. Upper and lower calypter both dark 
smoky brown. Infrasquamal setulae present (but minute and inconspicuous). 
6 genitalia with surstylus shaped as in Text-fig. 45, cerci much longer than the 
relatively small surstyli . : - C. canberrae 
Palpi and epistome yellow or tawny eellewe Crore is or Bees white, if 
largely smoky brown then at least basal half of upper calypter white. Infra- 
squamal setulae absent. ¢ genitalia with ae pee SS a as in Text-fig. 46, cerci 
shorter than surstyi . 4 
Ground colour of abdomen aan yallowih or very pale cedcice bean eh a 
conspicuous black median vitta (abdomen distinctly pallid to naked eye on either 
side of the black mid-line). Scutellum dark brown with little or no trace of 
metallic colour. : C. pellucida 
Ground colour of abdomen very dace metallic preeaisn or ooo appearing dark 
brownish in some lights only, darkest mid dorsally but without a definite black vitta. 
Scutellum distinctly metallic steely blue-black or purplish violet 3 
Third antennal segment uniformly bright orange. Parafacials bright aaa 
pollinose. Ground colour of parafrontals tawny reddish. Calyptrae almost all 
white, only the border darkened. Abdomen with pollinosity of the dorsum almost 
entirely whitish (at most only yellowish brown near the mid-line) 
C. argentifera, C. auriceps 
[C. auriceps is known only from the 2 holotype which has not been examined. 
Paramonov (1968) distinguished it from argentifera mainly by the yellow pollinose, 
instead of silvery whitish pollinose, parafrontals. It appears doubtful whether 
auriceps is specifically distinct from argentifera.] 
Third antennal segment partly or mainly brown, at least infuscate along one edge. 
Parafacials mainly whitish pollinose (if lower parts somewhat yellowish pollinose 
as in some @ specimens then calyptrae largely smoky brown). Ground colour of 
parafrontals blackish. Calyptrae at least faintly infuscate over much of their 
surface or lower calypter broadly darkened against hind edge, calyptrae of 9? 
usually dark smoky brown except for basal half of upper calypter. Abdomen with 
pollinosity of the dorsum mainly dark yellowish brown or coppery brown on the 
median third (the darker pollinosity of the middle of the abdomen contrasting with 
the whitish lateral pollinosity in some lights) . : . . : C. oblonga
