PLUTELLIDAE 



This family is now of only moderate extent, and contains no 

 dominant genera ; it would seem to have been in great measure 

 supplanted by its derivatives. Its characters, as usual in 

 very early groups except when isolated, are somewhat un- 

 defined and fluctuating. Although nowhere very prominent, 

 it is relatively more numerous in Australia, New Zealand, and 

 oceanic islands than elsewhere. 



Larva more or less elongate, with 10 prolegs ; usually 

 feeding in a slight web on leaves or seeds, seldom mining. 

 Pupa with segments 9-11 free, sometimes also 8 and in 12 : 

 usually not protruded from cocoon in emergence. 



An exotic genus is introduced (in brackets) into the 

 diagram, to explain the phylogeny; but the British genera 

 in any case give only an inadequate notion of the family.
