CRYPTOCOCCUS FAG I. 217 



smaller spine-bearing lobule, and there is a single long 

 slender hair arising from the base of each of the lobes 

 on the ventral surface. 



Ova (see fig. 1 b) lemon-yellow, very large in propor- 

 tion to the size of the insect, and often laid in strings 

 of four or five together, attached end to end. 



Habitat. Exclusively confined to the beech (Fay us 

 sylvatica). It is an abundant species, and one of the 

 commonest and most destructive of our native coccids, 

 and it is generally and very widely distributed through- 

 out the British Isles. In Scotland it has been 

 recorded from Dalkeith Park, near Edinburgh.* Dr. 

 William Somerville, Newcastle-on-Tyne, says, " The 

 insect is very common hereabouts, and, in fact, in most 

 parts of the country. It does a lot of damage too, 

 and I doubt if badly infested trees ever properly re- 

 cover, unless artificially assisted by dressings similar 

 to those used for American blight." * Kavensworth 

 Woods, co. Durham, is also given as a locality.* In 

 Yorkshire, Mr. J. Eardly Mason found it at Headingly, 

 near Leeds, where I have also seen it, and I found it 

 common in the surrounding districts. In Lancashire 

 it occurs at Huyton and Hainhill, near Liverpool. It 

 is everywhere abundant in Cheshire, and occurs in 

 several localities in both Flintshire and Denbighshire. 

 Mr. Burbidge has found it at Dublin, but I am not 

 aware of any other Irish records. It is injurious in 

 the woods on the estate of Lord Burton at Rangemore, 

 Burton-on-Trent. It is common near Stratford-on- 

 Avon (Hodges), and in the Ledbury district in Here- 

 fordshire. It occurs very sparingly in the extensive 

 beech woods between Birdlip and Pains wick in 

 Gloucester shire, but is injurious in the Forest of Dean. 

 In Norfolk it occurs near King's Lynn and Norwich. 

 In Kent it occurs at Chislehurst, and Mr. Green found 

 it in the Bearsted and Mailing districts. The Eev. W. 

 Wilks informs me that it is doing much damage to the 

 magnificent beech trees in the eastern districts of
