MasxeLL.—On New Zealand Coccide. 129 
Of the genera given above, the following have been reported by me as 
indigenous to New Zealand—Lecanochiton, Ctenochiton, Inglisia ; and several 
species of Lecanium have been introduced. | 
Strictly speaking, perhaps Ctenochiton, Vinsonia, Fairmairia, and Inglisia 
might properly be united under the same genus Ceroplastes. Still there is, 
I think, a sufficiently marked distinction between the tests of all to allow of 
their separation; at least, the distinction is quite as marked as that of the 
genera Aspidiotus and Diaspis in another group.

lst Genus, Lecanochiton, mihi.

Figs. 26, 27. 
I have found the male of this insect, last year. It has the generally 
normal form of Lecanide, the abdominal spike or sheath of the penis being 
moderately long, straight, and stoutish. Antenne (fig. 26) of ten joints, of 
which the first two are very short, the third much longer and expanded at 
the tip, the fourth more than twice the length of the third; the remaining 
six almost equal, about the length of the third, but stouter and rounder, 
being almost moniliform. All the joints but the first two have hairs. Foot 
generally normal; the tibia slightly expanded at its tip, with a strong spine; 
claw slender, with four digitules, fine hairs (fig. 27). Colour dark red; 
thoracic band inconspicuous. Length, exclusive of spike, about j^ inch. 
The test is white and glassy. 
When describing the female of this species in 1881 I had specimens 
only from rata trees in Milford Sound, at the extreme south-west of New 
Zealand. The male above described I found, with a great number of 
females, on the pohutukawa, near Auckland, almost at the extreme north. 
This last tree, Metrosideros tomentosa, of the same genus as the rata, does 
not grow, I believe, far south of Auckland. The occurrence of Lecanochiton 
on it is therefore another instance of the persistence of certain Coccids on 
certain trees. Milford Sound and Auckland are, I suppose, 700 miles | 
apart, but in both the insect attacks the same genus of plant. In the same 
way Inglisia leptospermi may be looked for with almost certainty on the 
manuka (Leptospermum) from one end of the islands to the other, and 
probably both it and Lecanochiton confine themselves to one kind of tree. 
Some Coccids, as the Dactylopii, or Fiorinia astelie, or Lecanium hesperidum, 
are not so particular. 
The antenne of the male Linda are peculiar, and distinguish it 
from all Coccids known to me. As a rule, the four or five terminal joints of 
the male antenne are elongated, in this insect they are nearly globular. 
This character, and the employment of the second pellicle in the test of the 
female, clearly differentiate the species.
