(Text fig. 2.) 



In general appearance a large broad golden insect, 

 measuring 14 mm. in length. 



Male. 

 Head rather broad, measuring '6^ mm. across the eyes. 

 Height of eyes about two-thirds that of head. Front 

 slightly over half the width of eye. Frontal stripe black, 

 tinged with reddish ])rown, and measuring about twice the 

 width of each parafrontal. Eyes red brown. Parafrontals 

 dark golden, almost brown; occiput and gense a beautiful 

 brown colour. First antennal joint clearly visible, though 

 not very large; second large, conical, nearly black; third 

 about thrice the length of second, a brilliant brown colour, 

 and tinged on outer border with black. Ptilinal suture 

 lodged in a distinct depression completely surrounding the 

 mesofacial plates and broadening out laterally, where it is 

 coloured black. Mesofacial plate brown, with very short 

 silvery pubescence and with borders tinged \nth black. 

 About fourteen facial bristles present ; vibrissa? not very 

 large. Thirteen epistomials present. Palps a brilliant 

 brown. Bristles on occiput golden, those clothing anterior 

 part of gena^ black. Two rows of black bristles behind e^^es. 

 of which the first is very regular, the second irregular. 

 Verticals present ; lateral verticals absent. A row of ten 

 frontals beside frontal stripe. 



Thorax about 4 mm. broad, golden, with the usual three 

 black longitudinal stripes. Of these the middle stripe 

 differs from that of all know'u Australian species in being 

 exceedingly narrow; on either side of it occurs another 

 longitudinal stripe rather more distinct than usual. The 

 last two pairs of anterior acrostichals are slightly differ- 

 entiated; of the posterior set, only the prescutellar pair is 

 well developed ; dorsocentral row complete ; three humerals 

 present. There is an indication of a third intra-alar. 



Legs black. First fenuir tinged very faintly with grey, 

 hairless; tibia slightly shorter than femur, also devoid of 

 hair ; tarsus slightly larger than tibia. Second leg hairless ; 

 femur devoid of a distinct comb. Third femur hairless ; 

 tibia hairy on its distal ventral half.
