Insect globular, a little elongate, covered with a white waxy mass ;

Pulvinarice, Maskell, Trans. New Zeal. Inst, xi, p. 205 (1879) : Sign., A. S. 

 E. F. (5 ser.) i, p. 424 (1871) ; iii, p. 29 (1873). 



This division is formed for the genus Pulvinaria, Targ., which in- 

 cludes those species in which the adult $ forms a mass of waxy- 

 resinous cottony matter in which the eggs are laid. To this genus 

 belongs the P. gasteralphe, leery, that attacks the sugar-cane in the 

 Mauritius. 



Subdivision Lecaniaria. 

 Sign., A. S. E. F. (5 ser.) i, p. 424 (1871) ; iii, p. 395 (1873). 



This group includes those species which are naked : they vary in 

 form, flat, or globular, or semi-globose and more or less smooth or 

 rugose. It comprises the following genera : — 



1. Species which are naked, flat or globular, smooth or rough, with 

 one joint in the lower lip and having anal lobes or scales : — Lecaniuniy 

 Illig. [Sign., I.e. iii, 395]. 



2. In which the adult 2 in its most advanced stage is divided 

 into two equal parts by a film formed of the skin of the abdomen which 

 remains stationary, whilst the insect continues to increase on its dorsal 

 surface until the lateral margins thereof meet and a ball-like form is 

 produced on the underside of which traces of a fissure may be seen : — 

 Physokermes, Targ. [Sign., 1. c. iv, 87]. 



3. Species in which the ? is spherical, more or less rounded, except 

 where it is attached to its food-plant, and the d* occur in masses along 

 and around the branches on which the insect lives : formed for the wax- 

 insect of China : — Ericerus, Guerin [Sign., 1. c. 90].
