460 Appendix /. 



Aspidiotus latanise (p. 49). 



The species here described under this name is not latania of Signoret, but 

 must revert to its earlier name transparens, Green (which is doubtfully distinct 

 from destmctoj- of Signoret). 

 Aspidiotus cydonise (p. 62). 



The oriental examples attributed to cydoniie are referable to /afanicc of 

 Signoret. American authorities are of opinion that cydonice of Comstock 

 is a distinct species. 

 Aspidiotus secretus (p. 64), Aspidiotus inusitatus (p. 66). 



These two species are now referred to the genus Odoiuispis. 

 Aonidia corniger (p. 69). 



The specific name should read ' cor/ugera.'' Cockerell has proposed a 

 new genus [Greeniella) for this and allied species characterised by the presence 

 of glassy, horn-like processes on the larval pellicle. 



Aonidia bullata (p. 72) should be referred to the genus Gyninaspis. 



Mytilaspis (p. Tj) has to give place to Lepidosaphes of Schimer, which has 

 precedence over Signoret's better-known name for the ' Mussel Scales.' 



Mytilaspis gloverii var. pallida (p. 85). 

 I now regard this insect as a distinct species. 



Diaspis amygdali (p. 87) gives way to the earlier name penlagomi of 



Targioni-Tozzetti. 

 Piorinia secreta (p. 102). 



Leonardi has referred this species to his new genus Adiscofiorinia. 

 Chionaspis. Synopsis of Species (p. 107). 



Species falling under section I. of the synopsis ('Median lobes approximate; 

 their inner edges in close apposition') form a sharply defined group which has 

 been separated from Chionaspis and referred to the genus Hemichionaspis 

 of Cockerell. I am, however, in agreement with Lindinger in the opinion that 

 Hemichionaspis is a synonym of Pimiaspis — proposed by the same author 

 (Cockerell) five years earlier. 



The genus Phenacaspis has been proposed for another group, represented 

 in this synopsis under Section II. B. While agreeing that there is a more or 

 less natural group surrounding the type species iiysscc, its boundaries are so 

 ill defined — grading off in one direction into Chionaspis proper, and in the 

 other direction into the Aulacaspis section of Diaspis — that I prefer to leave 

 these species in their present position, trusting that further study may enable us 

 to define the limits of the group with more accuracy. 



Chionaspis aspidistrse (p. no), Chionaspis these (p. 113), Chionaspis 

 musssendge (p. 117), Chionaspis rhododendri (p. 119), and Chion- 

 aspis scrobicularum (p. 121). 

 I now refer all these species to the genus Pimiaspis. 



Chionaspis albizzise (p. 115) is a synonym of Chioii. minor of Maskell, and 

 must now be known as Pinnaspis iiiinor. 



Chionaspis permutans (p. 130) should be referred to the genus Dinaspis, of 

 Leonardi. 



Chionaspis biclavis (p. 152) has been removed to the genus Howardia.
