but in that species these are simply two concentric circles, whereas in 

 C. wairoense they exhibit (fig. 49) an outer circle with six smaller ones 

 within it. 



The male pupa is bright red, and is enclosed in a small cylindrical sac 

 of white cotton slightly tinged with red. Apparently these sacs are found 

 in great numbers. A mass of several hundreds together was sent me on 

 one occasion, and, after about six weeks (in the depth of winter) two or 

 three hundred males emerged. 



Amongst this mass of male puparia were a few (perhaps half a dozen) 

 objects which I took for females, at least before the hatching of the males. 

 They certainly were not male pupa?, but I cannot exactly make out what 

 they are. They were much shrivelled, but on maceration in potash 

 regained their original form. Length about \ inch : the body elliptical, 

 segmented, generally resembling C. zcclandicum ; colour dark purple. 

 Antennae (fig. 50) of nine joints, all nearly equal in length, the first two 

 somewhat broad, the rest narrowing to the fifth and then widening again 

 to the last, which is almost globular. All the joints are short, and on each 

 there is one ring of hairs with tubercular bases, forming a sort of crown. 

 The eyes are small, tubercular and smooth, conical and a little projecting, 

 with a small terminal spot. Legs (fig. 51) strong and thick. The 

 trochanter bears one very long hair. Tibiae somewhat dilated at the 

 extremity, with a few spines on the inner edge. Tarsi thick, tapering 

 towards the claw, which is normal in shape, and has two lower digitules, 

 which are long, fine, knobbed hairs. Anal ring oval, without hairs. There 

 is no sign of anal tubercles. The segments of the body bear a number of 

 longish fine hairs with tubercular bases, interspersed with circular 

 spinneret orifices. These last show two concentric circles and a central 

 spot. The hairs and spinnerets are most numerous at the two extremities. 

 There are twenty-four spiracles, i.e., one at each side of each segment; 

 the spiracles are simple, and the tracheae small. There is not the least 

 sign of a mouth, neither rostrum, mentum, or rostral setae. I should have 

 mentioned that the tibiae are twice as long as the tarsi. 



I have not seen any specimens which I can take to be adult females, 

 nor any young larvae. I presume that the adult female will have antennae 

 of eleven joints. 



My specimens were sent to me by T. Cheeseman, Esq., of Auckland, 

 who informs me that the insect is found in the District of Wairoa, attacking 

 Phormium and Leptospermum. 



There is no doubt that this is a distinct species. The antennae and 

 legs of the male differ from those of 0. zaiandicum, bat the claw of the foot 

 is quite sufficient to distinguish it from that and all other Coccidne. I have
