Observations .—A number of specimens with a banded pro¬ 
boscis have been received from Dr. Bancroft from Queensland ; 
some of these he has labelled C. annulirostris, Skuse. C. annuli - 
rostris is the only species with an annulated proboscis described 
from Australia, Skuse having taken two 9’ s hi New South 
Wales. The series I have examined do not show any marked 
variation, and answer in so many respects to Skuse’s description 
that I take them to belong to that species. They differ, 
however, in the following respects, but, until I see specimens 
from New South Wales exactly answering his type, it is best to 
retain his name for the Queensland form. 
The scales on the head in Dr. Bancroft’s specimens are not 
yellow ; the thorax has bronzy scales, with sometimes a slight 
golden-brown tinge, with pale scales behind. Skuse says, 
“ rather densely covered with yellow scales and hairs,” but in all 
other respects the descriptions agree. 
The leg banding is rather variable in intensity, and the 
halteres seem to be either entirely ochraceous brown or with a 
dusky knob. 
The simple ungues in the 9 and the greater distance of the 
posterior from the mid cross-vein will at once distinguish it 
from the closely-related C. taeniorhynchus , Wied. 
Sub-species Bancroftii. 
A very distinct and handsome specimen has also been sent 
by Dr. Bancroft, represented by a single 
9 . The head is brown, clothed with pale 
yellowish curved scales, black upright forked 
ones behind and at the sides, and a central 
line of pale creamy curved scales, whilst 
the flat ones at the sides are quite white ; 
the palpi have a white patch at the apex. 
The thorax differs from the type in 
having, in addition to the flat spindle- 
shaped bronzy scales, a few dark yellowish 
ones every here and there, and with two 
patches of white curved scales in the middle, 
in front of the scutellum, and another patch 
just over the roots of the wings. The pos¬ 
terior cross-vein seems to be a little more distant from the mid 
cross-vein than in the type. Ungues, tkc., however, just the same.
