Scale Insects. 



Scale insects are not at all common within the Survey Area, with 

 the exception of Chionaspis salicis, L., which is common upon Ash, 

 Birch and variovis species of Sallow [Salix) from sea level to the upward 

 limit of the tree growth. 



Lepidosaphes uliiii {Mylilaspis pomorum) is to be found in some 

 gardens, but very seldom in any abundance. It does not occur in 

 such a manner as to suggest that it is native in the Area, and would 

 appear to have been introduced with nursery stock. It was abundant 

 on apples in one garden in Aberystwyth and upon a pear trained against 

 a wall in another. Elsewhere it only occurred in very small numbers 

 and then usually upon young isolated trees. 



Lecanium persicae (Geoffrey) has been sent me twice from private 

 gardens and L. capreae (L.) once from a similar situation. 



Nine species were obtained from indoor and green-house plants
