Distinction from J^. juncea. 



There is a great resemblance between A£. mixta and 

 ^F. Jnneea, but the following points will serxe to 

 distinguish them : (i) ^-E. mixta is smaller than 

 Ai. jnncea. {2) It has no black line separating frons 

 from nasus. (3) The costal margin of the wings is 

 brown in the former and golden in the latter. (4) The 

 arrangement of the nervures at the anal angle of the 

 hind-wings of the male is different in the two species 

 (Fig. ^6). (5J Pterostigma \\\ Juncea is longer than in 

 mixta.
