Genus FIORINIA (Targioni-Tozzetti). 



The female puparium consists almost entirely of the 

 moulted skin (exuviae) of the second-stage female, 

 which at the period of moulting becomes highly chiti- 

 nised, remains intact, and completely encloses the 

 adult insect. Dorsally it is usually covered by a very 

 thin secretion, but in F. Keivensis the covering is 

 abnormally thick, in which respect it differs from all 

 other known species of the genus. The larval exuvige 

 are always placed at the cephalic extremity. At first 

 the adult insect fills the moulted skin of the second- 

 stage female, but the body shrinks at gestation and 

 leaves room for the eggs, and subsequently the young
