150 DESCRIPTIONS OF AUSTRALIAN MICRO-LEPIDOPTERA, 



hither through Ceylon, thus not being truly aboriginal, whilst 

 the other, C. cuneiferellus, being thus left a solitary exception, 

 must be held insufficient to prove the native origin of the genus, 

 since it is more probable that with extended knowledge it also 

 wiU be found to be derived from elsewhere. 



I have been obliged to create several new genera, principally 

 in the Phycidce, where the variation of structure is considerable ; 

 some of these will doubtless be found to occur elsewhere. For 

 instance, it is possible that to Ftochostola should be referred the 

 species of Cramhus described by Zeller as having only three- 

 branched median veins, i.e., vein 5 absent in both wings ; but as 

 Ftochostola has other points of distinction, I can only conjecture 

 the relationship ; these species are G. incanellus,. Z., and C. 

 pygmcBUs, Z., (South America), C. troglodytellus, Snell., and C. 

 mconspicuellus, Snell., (South Africa). Again, to the genus 

 Cateremna is referable the European Euzophera terehrella, Zk. 



The distinction between the families of the CMlonidcB and 

 Cramhida, as hitherto constituted, is utterly untenable. Heine- 

 mann makes the difference lie in the cell of the hindwings being 

 closed in the Chilonid(B and open in the Cramhid(B, but in at least 

 half the genera of the Gramlidce, such as TMnasotia, Biptyckopliora, 

 &e., the cell is very distinctly closed, and the character is proved 

 merely a generic one. Zeller seems to rely rather on the 

 ChilonidcB frequenting water-plants and the Gramlidce dry ground, 

 surely a most unreliable and trivial point, and wholly inapplicable 

 in practice. I consider that Gliila is b}^ no means closely allied 

 to Schoenohius and Scirpophaga, but that its points of resemblance 

 are merely analagous and due to similarity of habit ; and I have 

 made the point of distinction between the two families consist in 

 the pectination of the lower median vein of the hindwings, which 

 is always present in the Cramhidcje, and absent in Schoenohius and 

 its allies ; Ghilo is therefore removed to the Gr ami idee. This 

 separation is in my opinion both natural and easy of application. 

 Indeed, so near is Ghilo to TMnasotia, that it was with difficulty
