Lecanium PERSiai;, var. ronjJi (Linn.) 



I have only found this species in the adult stage — viz., on Cofon- 

 ea'ifer microphylla, growing in a cemetery near Leamington, War- 

 wickshire. The colour is bright reddish-brown, more or less hemi- 

 spherical, of a very uniform pattern and size. 



Lecanium ciliatum (Newstead). 



I found this scale fairly common on oak-coppice shoots at High 

 Legh, Cheshire. The female may be first recognised, about the latter 

 end of May or beginning of June, by the conspicuous fringe which 

 surrounds the body. This is the period of fecundation, and it may 

 be compared to a large specimen of " mealy bug " we find in green- 

 houses. The whole body is covered with a whitish farinose secretion, 

 including the two anal lobes which project beyond the body. 



As this stage of the life-history of the species in question cannot 

 be called a starting-point, though in all probability the student may 

 also recognise them in the forest at the same stage, the following 

 note as regards life-history is taken from Newstead : — 



" The larvae hatch towards the end of July. At least one moult 

 takes place before winter, and the insect grows to some extent before 

 hibernating. In spring (March) the female appears, and is then about
