100 INSECTS NOXIOUS TO AGRICULTURE. 



A species easily distinguished by its cottony sac, its rich 

 colour in alcohol, and its conical spines. It would seem to be 

 intermediate between Rhizococcus and Dactylopms.

N.Z. Trans., Vol. XI., 1878, p. 218; Vol. XVI., 1883, 



p. 138. 



(Plate XVII., Fig. 2.) 



Adult female dull-pink in colour, elongated, distinctly seg- 

 mented, slightly convex; active; covered with thin mealy 

 secretion ; length variable, from Jin. to Jin. Very short 

 cottony appendages sometimes along the edge of the body. 

 Anal tubercles inconspicuous, bearing fine hairs, from which 

 spring two long cottony filaments. Anogenital ring large, with 

 six long hairs which are often glued together by white cotton, 

 forming a pencil between the anal tubercles. Interior substance 

 very oily. Antennae of eight joints, each bearing hairs. 

 Mentum triarticulate, with a few hairs at the tip. Feet 

 normal. 



Female of second stage similar, but smaller. Antennse of 

 six joints. Anal tubercles somewhat more conspicuous than in 

 the adult. 



Adult male unknown. 



Habitat On Calceolaria, Christchurch ; Danthonia, Stewart 

 Island; Phormiwn tenax, Christchurch. 



The large size, and the absence of long cottony marginal 

 appendages, distinguish this species from the European D+ 

 adonidum.
