Maskell. — On Coccidae. 309 



form to Fairmairia bipartita, Signoret, a small and curious 

 insect found on various plants in the South of France, and 

 described in 1874. When, in 1878, I first established the 

 genus Inglisia on a New Zealand species, I. patella, I was 

 influenced prineipallj" by the air-cells which are conspicuous 

 in the glassy tests. The test of F. bipartita is waxy, and I 

 cannot detect air-cells in it. But these are constant in all the 

 species of Inglisia which have been described since 1878, in- 

 cluding I. vitrea, Cockerell, 1894, a West Indian species. The 

 forms of the tests in this genus vary : some are almost semi- 

 cylindrical (J. leptospermi, I. inconspicua, &c.), some singly 

 conical {I. patella), some double {I. fossilis), so that there is 

 nothing to be founded on this. But I think that the glassy 

 structure and the air-cells may be considered as a sufficient 

 basis for the genus. 



Inglisia foraminifer, Maskell, var. major, var. nov. 



Differs from the type apparently only in size, being rather 

 larger, and in being perhaps rather greener in the colour of 

 the test. 



In 1892 I did not know the larva of this species. The 

 larva of var. major is yellow, flattish, elliptical, active ; length, 

 about /oin. Antennae short, thick, with six joints. Feet long 

 and slender; digitules all fine hairs. Abdominal cleft and 

 lobes normal ; setae long. Fragments of a waxy test are 

 visible on the margin. 



Hab. In Australia, on MuhlenbecMa adpressa. My speci- 

 mens were sent by Mr. French, from Swan Hill, Murray 

 Eiver. 



Genus Ceroplastes. 



Ceroplastes rubens, Maskell, var. minor, var. nov. 



Colours of insect and of waxy test as in the type ; also the 

 abdominal lobes, anal ring, cephalic papillae and antennae. 

 The size is smaller ; my largest specimens have a diameter of 

 only about ^in., whilst the type reaches |-in. 



Hab. In China, on Pinus sinensis and Pinus thunbergii. 

 Specimens sent from Hongkong by Mr. Koebele. 



C. rubens appears to be not uncommon. It is on several 

 plants in New South Wales and Queensland, and I believe 

 that Mr. Koebele has found it also in Japan and the Sandwich 

 Islands. 



Genus Lecanium. 

 Lecanium olese, Bernard. 



This species is very commonly known as the " black 

 scale." These trivial names are by no means satisfactory. 

 In the first place, there are many insects quite as black (or
