THE PANORPOID COMPLEX, 111., 



Family CASTNIIDiE. 



This family is only represented in Australia by the genus 

 Synemon. The genus Euschemon, originally placed in it, is 

 clearly, both from its venation and its life-history, far re- 

 moved from the Castniidae, and will be dealt with in this Part 

 under the Hesperiidae, to which it properly belongs. 



Text-fig. 94 gives a diagrammatic representation of the vena- 

 tion of the genus Synemon, with all the archaic characters found 

 in the various species included in the one figure. The very large 

 and handsome S. directa Walk., from Western Australia, was 

 found to possess the largest number of archaic features; so 

 that its venation approaches very closely to that of the figure. 

 In this species, however, there is no anal Y-vein in the forewing, 

 and 2A runs separately to the wing-border, as shown by a 

 dotted line in the figure.
