A NEW CERIOIDES WITH FOLDING WINGS.

ten of the thirteen known species being in Queensland and only four of 
these ten having yet been recorded from more southern States. It seems 
quite unlikely, therefore, that more than one species of the group here 
dealt with can occur in Southern Victoria, and none are to be expected 
from Tasmania, this being in conformity with other genera occurring 
mainly in Queensland. 
Ferguson comments upon the type locality “Port Phillip, South 
Australia ” as an apparent misstatement. Nevertheless this was quite 
correct, and the only alternative would have been “New South Wales ” 
which, at that time, covered the eastern half of the continent which was 
just beginning division into States The use of “South” referred to 
location in the sense of southern, not to the State of that name which 
was proclaimed a colony eight years earlier, 1836. Victoria, as a State, 
was inaugurated in 1851, six years after Saunders described this fly. 
Cerioides alaplicata n. sp. 
Male. — The antennal tubercle is about as long as broad, light brown 
in the colour, which extends a considerable distance around the base, 
merging into the black-brown median stripe which occupies about one- 
third the width of the face that is otherwise yellow. Below the yellow 
•occurs an upward sloping line from the oral margin to the eyes, below 
which the colour changes to black-brown, varying in intensity of the 
black, to brown below and without a definite pattern, and further 
-extends a short distance at the rear of the head, and above this the area 
behind the eyes is black with a slight grey pulverulent overlay. The 
-eyes are contiguous from the ocellar tubercle to two-thirds the distance 
towards the antennal tubercle, where the frons is yellow as on the face 
with a varying but narrow median brown area, this area forming part 
of the brown surrounding and on the antennal tubercle. The antennae 
.are blackish brow T n with the first segment about as long as the remainder. 
The thorax is black and quite normal, with two pairs of yellow 
dorso-lateral spots and the scutellum is margined with yellow, but these 
.yellow areas are liable to discolouration and reduction in size. 
The abdomen is black-brown with the long type of second segment 
The apices of the second to fourth tergites are margined with yellow and 
these three tergites are equal in length. 
The wings are quite normal in venation except that the fifth radial 
is only sinuous, the customary “dip” being absent. The brown of the 
anterior border extends over the whole radial area and also above the 
vena spuria from the radial median cross-vein to level with the furcation 
of the median vein. AVhen at rest the wings fold as described above, 
and the characteristic crease that indicates the folding and lies adjacent 
to the median vein is present. The legs are yellow to light brown with 
the basal half of the femora black.
