SCALE-INSECTS. 49 



Adult male doubtful ; very minute and difficult to detect. 

 Antennae apparently short and tibiae large. 



Habitat On Cordyline australis and C. indivisa, Phormium, 

 Gahnia, Astelia, Eucalyptus, &c., throughout the islands; but 

 the chief habitat seems to be C. australis (the common cabbage- 

 tree), on which it is often very abundant. 



This spec ;les may at first sight be mistaken for Fiorinia 

 stricta, described below, which also infests Cordyline and Phor- 

 mium ; but, on inspection, it will be seen that the puparium of 

 the Mytilaspis is much whiter, and the pellicles yellow, those of 

 F. stricta being black. An examination of the second pellicles- 

 of the two species will, of course, at once distinguish them. 



14. MYTILASPIS DRIMYDIS, Maskell. 



N.Z. Trans., Vol. XI., 1878, p. 196. 



(Plate V., Fig. 3.) 



Female puparium elongated, often straight, sometimes curved; 

 colour, dirty- white or brown ; pellicles at one end ; length, about 



Male puparium similar, but smaller. 



Adult female dull-red in colour, elongated, not very dis- 

 tinctly segmented. Abdomen ending in a number of small 

 lobes, of which the four median are the largest; several fine 

 hairs between the lobes ; no groups of spinnerets, but a very 

 great number of single ones, which are scattered on the segments 

 as far up as the rostrum. Many of these protrude as short 

 thick tubes with serrated or fringed extremities. On the 

 cephalic segment are a few spiny hairs and two rudimentary 

 antennae. 



Adult male red in colour ; antennae of ten joints ; tarsi 

 somewhat large. Both antennae and feet have numerous hairs. 

 Digitules, fine. 



Habitat On Drimys colorata, Water of Leith, Dunedin, 

 from which it has spread to other native plants. 



15. MYTILASPIS EPIPHYTIDIS, Maskell. 



N.Z. Trans., Vol. XVII., 1884, p. 21. 



(Plate V., Fig. 2.)
