4. EUCOSMID^. 



Ocelli present. Forewings with 2 from before | of cell. Hind- 

 wings with basal pecten on lower margin of cell. 



This family is very largely developed throughout the whole 

 northern hemisphere, but is less conspicuous in Africa and South 

 America, whilst in Australia and New Zealand it is much 

 inferior in numbers to the Tortricidfc. The real extent of its 

 inferiority in Australia, however, is partially disguised by the 

 number of species of Indo-Malayan type (especially in the genus 

 Argyrojiloce), which have penetrated into Queensland. It forms 

 roughly four natural groups, viz., {a) the primitive Laspeyresla- 

 group, with 5 of hindwings parallel to 4 (genera 66-7); (b) the 

 Aryyrojiloce-gvon^, with crested thoi-ax, to which Bactra truly 

 belongs, though it has lost the crest (genera 57-65); {e) the typical 

 ^?(.cosma-group (genera 52-56); and {d) the Spilonofa-groui:), with 

 notch in stalk of antennae in ^ (genera 49-51).
