136 FIORINIA FIORTNI/E. 



the margins either entire, or with an outer notch 

 towards the extremity. 



Second-stage female (PL XXIX, fig. 8) larger than 

 the adult insect, elongate ; has two or more sharp spine- 

 like projections on free abdominal segments. Pygidium 

 without circumgenital glands, otherwise not differing 

 materially from that of the adult. Towards the period 

 of moulting the dermis above becomes highly chitinised, 

 and subsequently forms the puparium of the adult 

 female, as already stated. 



Adult male unknown. 



Larva effects its moult in the same way as Diaspis. 

 Antennae of five joints, of which the last is longer than 

 the rest together; formula 5 (1, 2) (3, 4). 



Habitat (under glass). It is a pest on seedling 

 palms in Cheshire ; and I have received it from Scot- 

 land and Ireland on the same kind of plants, but did 

 not find it in the Royal Botanic Gardens, Kew. The 

 infested leaves turn a sickly yellow colour (PL XXIX, 

 fig. 10), with rusty-brown spots and blotches, which 

 are sure indications of its presence. 



Distribution. Is common in the open air in S. 

 Europe, U.S. America, Ceylon, Australia, and Brazil.
