Maskell. — On Coccidas. 395 



Larva orange-yellow, elliptical, slightly convex ; length 

 about eV^^- Dorsum sparsely covered with similar wax to 

 that of the second stage. Antennae of six rather confused 

 short joints, of which the last bears some hairs. Feet 

 moderate ; the tarsus is almost, or quite, as long as the tibia. 

 The margin of the body has the row of conical spines, and the 

 four longer ones, as in the second stage. The abdomen ends 

 in two conspicuous and prominent anal tubercles, each of 

 which bears a few fine spines and is terminated by a long 

 seta. 



Hah. In Australia, on Banksia serrata. My specimens 

 were sent by Mr. Froggatt from Manly, near Sydney. 1 have 

 asked him to procure, if possible, some adults, in the absence 

 of which I can decide neither the genus nor the species, 

 though there seems every probability that it will be a Kermes.

Adult female covered by a rather thick waxy test, whicli 

 is of a nearly brick-red colour, slightly elliptical and convex ; 

 length about jjjin. There is a median longitudinal raised 

 ridge of small tubercular swellings, each corresponding to a 

 segment of the insect ; on each side of this are two other 

 similar but smaller longitudinal ridges ; and, the shallow de- 

 pressions in all the ridges being continuous, the test has the 

 appearance of being transversely, and somewhat conspicuously, 

 corrugated and barred. The apex of each small tubercle is 

 lighter-coloured than the rest. Sometimes, however, the 

 whole test is almost or quite white : this may possibly be 

 due to incipient parasitism, although I can find no difference 

 in the enclosed females. The ventral surface of the test is a 

 flat plate of wax, with a perforation for the insect's rostrum. 

 At the posterior extremity, dorsally, there is a small orifice, 

 with somewhat protruded and raised edges. There is no 

 marginal fringe'; but in some specimens a small quantity of 

 white cotton may be seen beneath the edge of the test. 



Test of male pupa waxy, darkish-yellow, cylindrical ; 

 length about ^^qIu. Dorsally it has rows of small tubercles 

 like those of the female, but these are proportionately smaller 

 in comparison with the depressions, so that the test is more 

 conspicuously corrugated transversely, with the exception of 

 the posterior region, which is a flat sloping plate, hinged for 

 egress of the male. 



Adult female dark-red; filling the test, but shrivelling at 

 gestation. Form shghtly elliptical, convex dorsally. An-
