Maskell. — Oil Coccididae. 1-5 



with sloping sides. Upper surface formed almost eutiiely of 

 the pellicle of the second stage. Diameter of test at the 

 base about j^iu. 



Test of male elongated, white or yellow, glassy, convex, 

 divided into segments as in most Lecanidince, and with a pos- 

 terior hinged plate for egress of the insect. In some speci- 

 mens a quantity of white cotton is visible over the test. 

 Length about oV^^- 



Adult female convex, filling the test, brown ; base circu- 

 lar. Antennas with apparently only four joints, of which the 

 third is very long, the others very short ; on the last joint are 

 a few hairs. Feet absent. Some very minute hah-s are placed 

 in a circle near the margin. Abdominal cleft conspicuous ; 

 lobes adjacent, sub-conical. Anogenital ring with numerous 

 hairs. Mentum short and thick, dimerous. 



Female of second stage light-brown, flattish, elliptical, 

 naked, active ; length about g^oin. Abdominal cleft and lobes- 

 present. Antennae of six joints. Feet present, slender. 



Lar\-a flat, elliptical, brown, naked, active. Form normal 

 of Lccanidinc?, with conspicuous abdominal cleft and lobes. 

 Antennse rather long, with six joints, the thkd the longest ; 

 on the last are a few hairs, of which one is a good deal longer 

 than the rest. The anal ring appears to have six hairs. 

 Length of larva about ^in. 



Adult male reddish-brown, the wings rather tliick. An- 

 tennae with ten joints, the last five of which are not monili- 

 form, but elongated. The abdominal spike is long and curved. 

 Length of the insect, exclusive of the spike, about -a^n. 



Hah. In New Zealand, on Metrosideros robusta, in the 

 Reef ton district. 



This is much smaller than Lecanochitoii metrosideri, Mask., 

 and is easily distinguished by its very regular sub-cylindrical 

 female test. Indeed, at first sight the test may be easily mis- 

 taken for a pupa of some Aleurodid ; but the pellicle of the 

 second stage, as well as the antennae and lobes of the enclosed 

 insect, at once proves its Lecanid character. The antennae of 

 the adult are peculiar, and perhaps the long third joint may 

 really be made up of three or four atrophied and confused 

 joints. The male antenna differs from that of L. metrosideri 

 in not having the last five joints moniliform. 



Genus Ixglisia, Maskell. 

 Inglisia fagi, sp. nov. Plate III., figs. 15-25. 



Test of adult female usually conical, less frequently elon- 

 gato-convex, open beneath, with a distinct fringe of small seg- 

 ments which are often sharply triangular ; main segments 

 large, patched with brownish-green, or often altogether light- 

 green, sometimes white, distinctly striated with air-cells,
