the number to six. In a series that I have examined, I find examples 

 that have distinctly 7-jointed antennae (fig. 7-c.), and others in which 

 5 joint.s only are present (fig. 7-a). The 6-jointed form (fig. 7-b) is, 

 perhaps, the most common. 



A few paler and somewhat smaller individuals show more fully 

 developed antennae and limbs. These are probably female nymphs. 

 In place of the continuous lateral bands of ceriferous pores, found in 

 the adult, these supposed nymphs haA^e an isolated group of similai* 

 pores on each side of the prothoracic segment. The antennae, in this 

 stage, appear to be normally 7-jointed. 



I have also found still smaller examples that I take to l^e advanced 

 larvae. They are characiterized by slender 6-jointed antennae, the 3rd 

 joint longest ; a pair of longish caudal setae ; and four isolated groups 

 of ceriferous pores on each side, situated on the three thoracic and 

 first abdominal segments. 



Eriopeltis festucae Fonscol. 



Found, in great abundance, on a hill-side at Arundel (Sept.). It 

 occurs, but very sparingly, in the neighbourhood of Camberley. 



Chionaspis salicis Linn. 



Newstead gives broom {Cytisiis scoparius) as an occasional host- 

 plant of Ch. salicis. During the past summer, I found the stems of 

 every broom plant over a large area, on Weybridge Common, thickly 

 infested with the puparia of this species. 



Diaspis pentagona Tary. 



This species has been detected by Mr. Fryer upon cherry plants 

 imported from Japan. D. pentagona is recognizable by the large and 

 prominent median lobes, the bases of which are confluent (fig. 8). 



Diaspis persimilis Cidl. 



On Sideroxylon mermulatia, in piant house at Kew. Collected by 

 Mr. F. Laing. 



The species may be distinguished from pentagona, (which it some- 

 what resembles) by the smaller median lobes, the bases of which 

 remain separate and distinct. There are other differences that may be 

 appreciated by a comparison of figures 8 and D.
