second posterior cell broad, its base nearer the base of the wing 
than that of the first sub-marginal cell; posterior cross-vein 
nearly twice its own length distant from the mid cross-vein, both 
very pale; veins with a row of small dark scales; the apical 
portions of the second to fourth long veins with lateral spindle- 
shaped ones; halteres with a pale stem and fuscous knob. 
Length .—2 mm. 
Time of capture .—July. 
Habitat.— Bupengary, Queensland (29. 5. 1899). 
Observations .—A very distinct species, with very characteristic 
silvery markings, notably on the base of the wings in front, on 
the prothoracic lobes, and on the wings themselves. In many 
respects it might be mistaken for C. atripes of Skuse, but the 
first sub-marginal cell is quite different from Skuse’s G. atripes. 
One specimen resembles the one from which this description was 
taken, but the white markings are absent. I cannot, however, 
see sufficient characters to separate it. Although there are 
certain striking resemblances to 0 . atripes, the first sub-marginal 
cell is narrower and shorter instead of much longer and scarcely 
narrower than the second posterior cell. The apical abdominal 
banding is not mentioned by Skuse, and the still more striking 
silvery-white line on the wings could not have escaped his observ¬ 
ation. This small species is undoubtedly a typical Uranotaenia , 
most nearly approaching Arribalzaga’s U. pulcherrima, but 
instead of having blue flat scales, as one finds in the South 
American species, the scales are brilliant wffiite as in the African 
U. caeruleocephala and U. domestica. 
8. Uranotaenia caeruleocephala. n. sp. 
Head with shiny azure-blue scales. Thorax chestnut-brown, 
with a small silvery-white spot on each side in front, a white 
line on each side just in front of the wings. Abdomen and legs 
brown, unbanded. 
Head covered entirely with flat azure-blue scales, slightly 
paler around the eyes, and with black upright forked scales 
behind, the apices of the forks bent (Fig. 276); a large lateral 
black bristle on each side curved inwards, two smaller ones in 
the middle, and two nearly parallel small ones between the eyes 
pointing forwards; antennae brown, with rather large joints; 
basal joint deep brown; proboscis brown; palpi black, very 
minute.
