Noctuide ; in three genera vein 5 of the hind wing is somewhat 
aborted from below the middle of the discocellulars and in these 
the larve are semiloopers with the first two pairs of abdominal 
prolegs absent, whilst in all the other forms of the four subfamilies 
the four pairs of abdominal prolegs are present. 
The four subfamilies are modifications of the great Quadrifid 
section of the Noctuide and are almost confined to the tropical and 
warmer temperate regions, few genera and species extending to the 
colder zones, and none to the Arctic and Alpine zones. 
Sir George Hampson has to acknowledge the assistance which 
he has received, mostly from those whose help has been referred 
to in earlier volumes of the Catalogue, by the loan of types and 
specimens, and in other ways. 
The coloured drawings which have been made for him from types 
of species which are not in the collection of the British Museum, 
and of which he has been unable to examine specimens, have been 
reproduced and are severally acknowledged in the text. 
The Plates published in connection with this volume are numbers 
CLXXIV.-CXCLI.,, part of Plate CLXXIV. referring to Vol. X. of 
the Catalogue,
