Chionaspis fodiens (p. 155). 



This insect is certainly not rightly placed in the position to which I had 

 assigned it. I would, for the present, allow it a place in Ferris's genus Ancep- 

 aspis, though I appieciate the fact that it is not strictly congeneric with the 

 type of that genus. 



It is problematical whether the male puparium, described and figured as of 

 this species, is correctly assigned to fodietts. 

 Chionaspis simplex (p. 160) is referable, more probably, to the genus 



Odonaipis. 

 Parlatoria mytilaspiformis (p. 164) is now regarded as an exceptionally 



elongate form of pro/cus. 

 Lecanium (p. \tj). 



As pointed out in a footnote on this page (and with more detail on p. 248), 

 the name Lecanium has been superseded by Coccus, with a corresponding 

 change in the name of the sub-family. The old genus has also been sub- 

 divided by the erection of numerous new genera and sub-genera, the characters 

 of which (with a few exceptions) appear to me to be too elastic for practicable 

 adoption. As the name Lecamuin has never been applied to any other genus, 

 while Coccus is the more generally known name of the Cochineal insects, no 

 confusion can arise from the retention of the former name in the present work. 

 Lecanium subtessellatum (p. 206), Lecanium tessellatum van 



perforatum (p. 207). 



Examination of long series, from various host plants, has convinced me 

 that both of these species are referable to tessellatum of Signoret. 



Neolecanium crustuliforme (p. 252). 



Professor Cockerell has advised me that crustuliforme cannot be included 

 in his genus Neolecanium^ but that it would be referable, with more justice, to 

 the genus Platysaissetia. 



Asterolecanium lineare (p. 336). 



The name lineare being preoccupied, the name lanceolatum has been 

 adopted for the species here represented. (See Prefatory Note to Part I\\) 



Pollinia ceylonica (p. 341). 



My original description of this insect was drawn up from inadequate and 

 badly preserved material. Fresh material, obtained since the publication of 

 Part IV., reveals several characters that could not be observed in the older 

 specimens. There is a continuous marginal series of equidistant, simple, 

 circular pares, with other similar (but slightly larger) pores distributed sparsely 

 over the dorsum. There is a complete absence of paired (8-shaped) pores. 

 The ovisac bears scattered, isolated, crook-shaped, glassy filaments, but no 

 definite marginal fringe. The margin of the ovisac is narrowly flattened and 

 out-turned. 



The species is clearly not congeneric with Pollinia polli/ii; and the 

 absence of paired pores precludes its inclusion in the genus Asterolecanium, to 

 which, in all other respects, it is most closely allied. I therefore propose to 

 erect a new genus (the characters of which will be found below) for its recep- 

 tion. 1 call this new genus Polea, in commemoration of the late John Pole, 

 who assisted me so assiduously in the collection of material for the present 

 work.
