wings erect above the back when at rest. There are some 



moths that have 

 clubbed antennae,and 

 others that fly by day 

 but no moth presents 

 all three of the charac- 

 teristics given above. 

 It is more difficult 

 to distinguish the but- 

 terflies from the skip- 

 pers : yet this can be 

 easily done. In but- 

 terflies the club of 

 the antenna is bluntly 

 rounded at the tip 

 instead of being fur- 

 nished with a re~ 

 curved point as in 

 most skippers ; the 

 abdomen is very slen- 

 der ; and some of the 

 branches of radius of 

 the fore wings co«

apex of the discal cell (Fig. 455). There are butterflies in 

 which all of the branches of radius present arise from the 

 discal cell ; but this is due to the fact that two of the 

 branches coalesce to the edge of the wing, as is shown by 

 the fact that in these butterflies radius has less than five 

 branches. ^ 



This superfamily includes four famiHes, which can be 

 separated as follows : —
