to the margin ; and the lateral irregularities may sometimes 

 be resolved into seven or eight indistinct tuberosities. Diameter 

 of test variable : specimens observed range from i X T in. to Jin. 



The test of the second stage appears to be similar to that 

 of the adult, but smaller ; it is very difficult to make out the 

 lateral tuberosities, which sometimes seem to be only five. 



Test of the larva in its latest period before the first meta- 

 morphosis whitish, waxy, stelliform, having usually eight 

 lateral radiating processes and a dorsal convex mass of wax : 

 average length of the whole about ^in. 



Adult female extracted from the test yellowish-brown or 

 dark-brown ; subcircular, convex above and concave beneath ; 

 form normally Lecanid ; anal cleft small, lobes triangular, 

 each bearing a short seta ; anal ring with six strong hairs. 

 At the cephalic extremity there is a dorsal elevation or tube- 

 rosity, which bears several small subcorneal papillae. Antennae 

 of six joints, of which the third is much the longest. Feet 

 nearly atrophied, short, thick ; tarsus very short, claw small, 

 digitules slender knobbed hairs. Eostrum rather large ; men- 

 turn monomerous. On the margin, near the four spiracles, is 

 on each side a patch containing one large thick conical spine 

 and about twenty other smaller ones. Dorsal epidermis bear- 

 ing some small circular spinneret-orifices. 



Larva dark-yellow, flatfish, elongated, distinctly Lecanid. 

 Eyes large, brown. Antennae of apparently six joints, but the 

 fourth and fifth are not easily separable. Length of insect in 

 this stage about y^in. at first, increasing to about -g^in. with 

 age. 



Male unknown. 



Hab. On Mangifera indica (mango), and on Ficns (F. 

 macrophylla ?), the Moreton Bay fig, Brisbane, Australia. 

 Mr. Koebele sent me several specimens. 



I have ventured to consider this as a new species, although 

 I am not sure that it is not at least closely allied to G. myricce, 

 Linn., a species originally from the Cape of Good Hope on 

 Myrica cerifera ; and, indeed, my first idea was to attach it to 

 that species, the latest description of which (as far as I know) 

 is given by Fabricius (Ent. Syst., 1794, iv., 227). But, after 

 careful consideration, I find that C. myricce. is not only white 

 in colour towards the edges (the centre being reddish), but also 

 convex — "vertice obtuse acuminatus " — and that the margin 

 bears seven distinct tuberosities. The flat vertex and agglo- 

 merated margin of C. rubens do not answer to such a descrip- 

 tion, and I therefore place it as a separate species, subject of 

 course to future correction. 



The wax of C. rubens dissolves readily in potash : on cool- 

 ing it recoalesces, and I have always found it lose its red 

 colour and become white.
