Coelostoma immane, Maskell. 
The female of Calostoma immane, one of the Monophlebide, is 
probably the largest sized of all Coccids, was first figured and 
described by the late F. M. Maskell in the Transactions of the 
New Zealand Institute, 1891 (p. 49, pl. XJ., figs. 9—12), and 
afterwards mentioned repeatedly in subsequent volumes up to 
1898. The male has, however, remained unknown hitherto, it 
seems, although it is mentioned by Maskell that the species was 
reported as having been observed near Sydney on some kind of 
Eucalypts. Nor was the precise locality known where the 
original type specimens in the South Australian Museum had 
been collected, as they were received without any note or 
indication, except a half-obliterated postmark indicating the 
Far North. Both these points are now cleared up by a parcel: 
of specimens received at the S.A. Museum on September 5th 
of this year, having been sent by Mr. George Prout from the 
Wheal Turner Mine, in the neighbourhood of the Yudanamutana 
and Umberatana Stations, north of Port Augusta, to Prof. R. 
Tate, who courteously handed them over to the Museum 
Collection. 
Some six or seven females, fixed to the twigs of Acacia aneura 
(Mulga), were still fresh, and some of them actually alive. They 
were of various sizes, the largest measuring 35 mm. in length, 
and 17 mm. in width; but with them were also about twice as 
many males enclosed, which were, however, all dead, and unfor- 
tunately, more or less distorted and damaged. There were like- 
wise a quantity of eggs which had been deposited in transitu. 
The antennz of the females are stout, ten-jointed, 9 mm. long, 
gradually attenuated from the base to the apex, the joints sub- 
cylindrical, and each apparently with a narrow white annulus at 
the base. The body segments are distinctly separated by more 
or less deep constrictions ; hence the margin is sinuate, besides 
being otherwise sculptured above with mature individuals, the 
young ones being almost smooth and entire in this respect. 
The whole body in life is covered thinly with a mealy-white 
layer of wax, which also covers the twigs and foliage near the 
specimens, and appears not to be dissolved by strong methy- 
lated spirit. In formaline solution the wax forms a more or
