the completion of the snowy white ovisac, it is readily 

 noticeable. 



The genus Liiziilaspis [ = Suinoretia) might be described as a very 

 narrow and elongate form of Lichteusia, the ovisac covering all but 

 the anterior extremity of the insect. There are, however, structural 

 characters to justify the separation of the two genera. 



L. Ittziilae, Dufour. On the foliage of the wood-rush {Liizida cam- 

 jn'Htria). The elongate, narrow, snowy white ovisacs are 

 sometimes conspicuous objects on rough pasture land. 



The genus Kxaeretopnn is distinguished from other genera of the 

 Lecaniiuae by the presence of a deep fold across the middle of the 

 tarsi of the front limbs, giving that segment the appearance of being 

 2-jointed. 



E. lovgiconiis, Green. On Care.v oralis ; on the upper surface, near 

 the base of the leaves. Adult female orange-yellow, at first 

 resembling an elongate, fiattish Lecaniuw ; but, subsequently, 

 almost completely concealed by a closely felted, cylindrical, 

 white ovisac. 



Lecanopsis. It would be difficult to characterise this genus briefly 

 and concisely. I will content myself with a reference to our only 

 British species. 



L. forinicario)}, Newstead. Early stages on the roots of grasses ; 

 the nymph enclosed in a brittle, glassy test. The young 

 adult females ascend the grass stems; but, after fertilisation, 

 descend to the surface of the ground, where they construct 

 lodse, woolly ovisacs, filled with rose-red eggs, under moss 

 and debris at the base of the tufts of grass. They are most 

 frequently associated with the grass Festuca <)vi)ta. The 

 insect itself is of a yellowish or reddish colour. The nymphal 

 stage was originally regarded as belonging to a distinct 

 species — L. brcviconiis. The regular association of this 

 insect with ants is doubtful, though occasional individuals 

 have been taken in the nests of ants. 



In the genus Eriopdtix the mature female is completely enclosed 

 within a felted sac. The legs and antennae are atrophied. 

 E. festnrae (Ponscolombe) (fig. 5 <'). On grasses of the genus Festnca. 

 This is probably the most conspicuous of all our British 

 Coccids. The large, white, strongly convex ovisac may 

 attain a length of 7 nim. It is of a loose woolly texture and 

 has many erect, projecting filaments, which give it a 

 markedly shaggy appearance. The contained insect is of 

 a pallid ochreous colour, the surface rou<,'hened like shagreen 

 owing to the presence of numerous conical spines.
