Lecanium capreae L. 



Hazel bushes, in the neighbourhood of Camberley, wei'e found to 

 be heavil^'^ infested by a species of Lecanium. When first observed, in 

 the month of May, they were not fully mature, having still the varie- 

 gated pattern of the early adult stage. The ground-colour was dark 

 castaneous, with erect whitish bands on each side. This colour-pattern 

 is not quite typical of the species ; but the structural characters agree 

 with those of capreae. 



I have also received examples of capreae, taken on bushy Elms, at 

 "VVanstead Park, near London. 



Lecanium persicae Geoff, var. rohiniarum Dougl, 



An Acacia {Robinia) tree, in my garden at Camberley, is infested 

 by the form of persicae referred by Newstead to var. sarothamni. This 

 is evidently the Lecanium rohiniarum of Douglas. Newstead, ap- 

 parently, ignores Douglas's name and does not even place it as a 

 synonym of persicae ; but, having been published in 1890, it has 

 priority over sarotliamni (1891). It would appear, therefore, that 

 this form of persicae should be known as var. rohiniarum, rather tlian 

 as sarothamni. 



Mr. Donisthorpe has sent me specimens of tliis insect, which he 

 records as being " abundant on bramble stems in the New Forest ; much 

 attended by D.fuliginosa.^'' The species does not appear to have been 

 recorded from this Iiost-plant before. Douglas mentions having found 

 L. ruhi on Bramble ; but Newstead places o'uhi as a synonym of 

 capreae. 



Pulvinaria vifis L. 



Male puparia oecm' abundantly, on Birch and Alder, in the neigh- 

 bourhood of Camberley, in August and early September. Twigs may 

 be found thickly encrusted with the puparia, giving them a frosted 

 appearance. Such male colonies contain many hundred individuals — 

 the produce of a single female insect. The winged males emerge 

 during the second half of September. 



LicJitensia vihurni Sign. 



This insect, if of more common occurrence, would rank as a trouble- 

 some pest of ornamental Ivies. I found it thickly infesting a varie- 

 gated Ivy, on a house at Stroud (Xiloueestershire), where it was 

 responsible for a considerable loss of foliage, besides making the plant 

 unsightly by the consequent growth of sooty fungus. The colonies
