6 ON THE GALL-MAKING C0CCIU.9i,, 



shape of the cavity occupied by the female, and fig. o. the female 

 taken therefrom, natural size. Fig. s. the gall of the male insect. 



The sketch x. shows a gall of B. munita. 



There are other species of smaller gall-making Cocci, in Avhich 

 both male and female excrescences are on the same leaves. The 

 males are of a red colour, some with and some without anal setae, 

 and the females with vei-y long posterior legs, the anterior and 

 intermediate missing. 



I intend to make these insects the subject of my next paper, 

 which will also include another genus of gall-makei^s, in which the 

 male larva3 undergo their metamorphosis, in the gall of the 

 mother, and where the females lose nearly all traces of ai'ticula- 

 tion, becoming fixed masses of animal matter, without apparent 

 limbs, or sign of vitahty.

In my last paper I gave you the result of my observations on 

 the genus which I have named Brachjscells. I now proceed to 

 the description of some insects so remarkable in their form, that I 

 have ranked them as composing distinct Grenera. 



I propose therefore to divide the gall-making Goccida' as 

 follows : — 



1. Genus. Bmchi/ficeJi.i. Where the females Imve six legs 

 complete, but short, and unfit for use. 



2. Genus. Ojpisthoscelis. Where they have only two lonp- 

 posterior legs. 



3. Genus. Ascelis. Where there are no vestiges of legs. 

 The galls of the insects of the genus Opkthoscelis are often
