Aspidiotus zonatus, Frauen. 



A large colony of male puparia, on the underside of the leaves 

 of Quercus pedunculata. 



These examples formed the prettiest little colonies that I have 

 jet seen in this country, and they were unusually numerous, 

 though the females were very scarce. 



Dactylopius citri, Risso. (Living adult females and empty male 



puparia.) 



On My Hit 8 communis, var. tarentina. Coll., W. B. Little, 

 (30.1.08). The host plant was growing against a wall, some distance 

 from a glass house. This record is therefore of great interest as 

 showing the hardy nature of this insect. It is, I believe, the 

 common practice among horticulturists of this country to expose 

 bug-infested houses to the action of frost with the view of ridding 

 such structures of meally bug. In the light of this discovery it is 

 quite evident that such measures must be altogether futile. 



II. FLORA.

A. B. Jackson. 

 3, var. americanum, Harz. Rough grassy and 



Arboretum and elsewhere. It differs chiefly 



much 



mor 



with spreading not appressed pubescence. No doubt of American 

 origin and only found here in a naturalised condition. Harz 

 points out (Bot. Centralb. 45, 106) that large quantities of 

 the seed of this American form are sown in Germany, and I 

 am informed by Messrs. Sutton that it is cultivated to some 

 extent in this country. They state however that, while in special 

 cases it may prove very luxuriant, yet its height and vigour differ 

 with soil and climate, and they have not found it to be any more 

 productive than other strains. It seems, too, to be affected by 

 variations of temperature and on account of this susceptibility is 

 not strongly recommended as a fodder plant. 



Scirpus maritimus, L. This species, which has been inadver- 

 tently omitted from the Kew list, occurs within our area on mud 

 banks by the river associated with Eleocharis pahistris, Scirjnis 

 triqueter, S. car inatus and other moisture-loving plants. It is rare 

 inland but has been known as a Thames plant for over a century, 

 and is still holding its own here. The figure in Curtis VI. 

 Londinensis is drawn from a Thames specimen. See Trim. 

 & Dyer, Fl. Middlesex, 299 (1869). 



Lolium italicum, A. Br., var. muticum, DC. Rough unmown 

 places about the Arboretum, especially near the Palace. This 

 awnless variety of the Italian Rye-grass grows here with the type,
