Maskell. — On Coccidse. 39 



teristic long hairs of the abdominal extremity, partly simple 

 and partly serrated, and the single pair of lobes, are so clear 

 that the identity is manifest. I think, however, that there 

 are six of the long simple hairs on each side, and not four as 

 given b) 7 Mr. Morgan. 



A minute, bright-red mite (seemingly Gamasid) was very 

 active and numerous amongst these Sandwich Island speci- 

 mens ; and I found many of the Aspidioti which appeared to 

 have been partly devoured, whether by this or some other 

 parasite I could not determine. 



Aspidiotus camellise, Boisduval. A. rapax, Comstock. 



This insect is still very prevalent in New Zealand on many 

 plants. It has lately attacked Diosma in the gardens near 

 Wellington. I have also had specimens sent to me by Mr. 

 Froggatt, from Sydney, on Melaleuca nodosa, and by Mr. 

 French, from Melbourne, on Rhododendron. The species 

 seems to be omnivorous, and bids fair to be cosmopolitan. 



Aspidiotus ficus (Riley), Comstock. Comstock, Ent. Eep. 

 U.S. Agric. Dept., 1880, p. 296. 



This species, which in North America appears to be an in- 

 jurious pest on orange-trees, has been sent to me during the 

 last year from New South Wales (by Mr. Froggatt) and from 

 Queensland (by Mr. Koebele). The characters by which A. 

 subrubescens mihi (1891) differs from it will be found in vol. 

 xxiv. of our Transactions, p. 9. The Australian plants on 

 which my specimens of A. ficus came were not named by the 

 senders ; but I imagine them to be various kinds of Citrus.

Aspidiotus ceratus, sp. nov. Plate I., fig. 1. 



Female puparium snowy-white, circular, convex ; diameter 

 about ^gin. when separate; but numbers of puparia are 

 usually so massed together that measurement is difficult. 

 Texture solid and waxy ; the two pellicles are central and of 

 a faint yellow tinge, covered by a scale of white wax. 



Male puparium white, smaller, and more elongated than 

 that of the female. 



Adult female orange - colourpd, pegtop - shaped ; length 

 about Tnjin. Abdomeu ending in two adjacent lobes with 

 rounded emarginate ends ; above them are two club-shaped 

 organs. The abdominal margin is serratulate and bears some 

 short spines : of these spines, one on each side, not far from 

 the lobes, is widely forked. No groups of spinnerets. 



Adult male unknown. 



Hab. In Australia, on Acacia stenophylla. Mr. French 

 sent me specimens from the banks of the Murray River, in 

 South Australia.
