494 DESCRIPTION'S OF ArSTRALIAlS' MICEO-LEPIDOPTERA, 



apex, 2 from rather before angle o£ cell, fork of 1 strongly dilated. 

 Hindwings with vein 5 bent and strongly approximated to 4 at 

 base. 



Differs from Eulechria (to which it is not in fact immediately 

 related) through the absence of a complete basal pecten of 

 antennae, the dilated abdomen, and the approximation of veins 4 

 and 5 of the hindwings at base. It must be considered as 

 developed directly from Heliocausta through Euryplacci, its 

 relationship with Eulechria being merely collateral. The genus 

 is of some extent, and has given rise to several offshoots, which 

 have been already discussed. 



The perfect insects are inactive, and seem attached to species 

 of Eucalyptus. I have thirteen species, some of which are closely 

 allied ; the following is a tabulation of them :
