Young insect normal. 



Adult male yellowish-red in colour, about ^in. in length, 

 exclusive of the wings. General form normal. Antennae long, 

 with ten joints, all long and equal, except the two first, which 

 are very short : all the joints have several hairs. Legs normal, 

 but the tibise are very long and slender, and only a little thick- 

 ened at the tip ; tarsi somewhat thick ; digitules fine hairs. 

 Abdominal spike long, and very slightly curved. 



Habitat On Plagianthus, Cyathea, &c. j Hawke's Bay. 



This insect resembles, to the naked eye, somewhat nearly 

 Ctenochiton perforatus, but the female differs in the absence of 

 the curious perforations in the test of that species, and in the 

 shorter and thicker antennae, with also more long hairs on the 

 last joint. The test of the male is also different.

 (Plate VII., Fig. 3.) 



Test of adult female oval, nearly circular, black in colour, 

 divided into hexagonal and pentagonal segments which are not 

 conspicuous, and of which the median series forms a very 

 slightly elevated ridge somewhat lighter in colour. The test is 

 only slightly convex. The fringe is very long and conspicuous, 

 the segments toothlike. Diameter of test, exclusive of the 

 fringe, reaches Jin. 



Test of male unknown. 



Test of second stage of female white, waxy, not homogene- 

 ous, but built up of a number of loosely-aggregated tubuliform 

 plates, somewhat resembling those of the genus Orthezia, Bosc. 

 The fringe of this test is longer than in that of the adult, the 

 teeth curling in different ways. Length of test and fringe, 

 sometimes Jin. 



The adult female fills the test, shrivelling at gestation. 

 Colour black. Antennae somewhat long, of seven joints ; a few 

 hairs on the last joint. Foot normal; upper digitules strong 

 and thick, lower pair very broad. On the skin are a number 

 of large oval spots which appear to be the orifices of spinneret 

 tubes. 



Female of the second stage wanting the usual wavy edge of 

 the genus. Round the edge of the body is a row of sharp
