a. p. — apex of primaries — with a pale apical spot. 

 h. a. — hind angle of primaries. 



c. m. — costal margin. 



0. m. — outer margin of primaries ; o. m.', same of secondaries. • 



i. m. — inner margin of primaries ; i. ?H.',same of secondaries. 

 h. a. — hind angle of primaries. 



d. 8. — discal spot on secondaries. 



e. I. — exterior line on secondaries. 

 apex — apex of secondaries. 



*. >H. — submedian, or internal vein,
