Larva mines an irregular slightly inflated discoloured blotch 

 occupying apical half of leaves of Banksia integrifolia {ProteacecB) 

 ejecting excrement through several small holes, in April. Pupa 

 in a very slender close white cocoon, suspended in the air hy 

 stretched threads from each end. 



The habit of the pupa is, so far as I know, quite peculiar in 

 the family. 



Cemiostoma, Z. 



Head smooth, rarely with erect hairs behind ; no ocelli ; tongue 

 rudimentary. Antennoo shorter than forewings, filiform, with a 

 moderately large eyecap. No palpi. Forewings elongate, 

 moderately narrow, pointed, apex rather produced. Hindwings 

 linear-lanceolate, much narrower than forewings, cilia four times 

 as broad. Forewings with 7 or 8 veins ; 2 or 3 branches to costa, 

 cell open or finely closed, 1 simple. Hindwings without cell, 

 median three-branched. 



Larva sixteen-legged, mining large flat blotches in leaves, or 

 galleries under cuticle of shoots. Pupa in a silken, often ridged, 

 cocoon, usually without the mine. 



This genus has not hitherto been observed outside Europe, 

 where are about a dozen closely allied species. There is no doubt 

 that the following species is a true Cemiostoma, though I have 

 not yet been able to examine the neuration. The genus is well 

 distinguised by the smooth head and absence of palpi.

^. 0"-o]". Head, antenna), thorax, abdomen and legs snow- 

 white. Forewings snow-white ; a slender very oblique dark 

 fuscous streak from costa at two-thirds, reaching half across 

 wing; a second, much shorter and much less oblique, in costal 

 cilia at five-sixth ; a third as short as second, inwardly oblique, in 

 costal cilia immediately before apex ; a smal roundish brassy- 

 metallic spot on anal angle, margined anteriorly and posteriorly
