The largest species of the group, and not to be coufused with 

 any other known ; the very elongate fore-wings have a peculiarly 

 glossy appearance. 



Larva sixteen-legged, very stout, tapering at both ends, head 

 much narrower than body, whole surface with a few scattered 

 hairs ; darker or lighter dull drab-brown, spots, small, black ; 

 head and second segment black ; anal segment with a small black 

 plate. Feeds in the tall spike-like flower-heads of Xanthorrhaa 

 hastilis (the so-called 'grass-tree'), burrowing amongst the seeds 

 and forming tough galleries with silk and refuse, in October. 

 Pupa in a firm cocoon amongst refuse. These larva) were very 

 restless in captivity, and could hardly be restrained ; they occurred 

 gregariously in the heads, one spike containing apparently nearly 

 100 Iarva3 of different sizes, who eventually consumed the entire 

 head. My specimens were bred in November ; I have never 

 taken the imago at large ; it is probably very retired in habit. 

 The larval habits of this species are abnormal in the genus and 

 family ; all previously known larva) are parasitic in habit, feeding 

 in the nest of bees on the wax ; this species is therefore of peculiar 

 interest. 



My larvae were found near Sydney ; Zeller's original specimen 

 was from Adelaide. 



The venation of this species differs from that of the others 

 investigated in having veins 8 and 9 of fore-wing rising on a 

 short stalk, instead of separately, from 7. 



For the benefit of students, I add a classified list of all the 

 species of Crambttes mentioned in this and my preceding paper.
