mination of Cuj at wing- margin; (jalapensis is fairly inter- 

 mediate in these characters). 



2. In mutata the anal loop is distinctly wider, with a median 

 cell and shorter outer side than in multicolor; (jalapensis has 

 a wide anal loop of a form similar to mutata, but the outer 

 side is variable in length). 



3. Mutata has a larger number of cells in the wings as 

 shown by: 



a. The presence generally of two rows of cells throughout 

 between M 3 and M 4 in hind wing distal to point where two 

 rows of cells first appear between these veins ; (jalapensis inter- 

 mediate) . 



b. The larger number of cubito-anal cross veins in both front 

 and hind wings ; (jalapensis intermediate). 



c. The larger number of cells in the triangle of hind wing; 

 (jalapensis resembles multicolor}. 



d. The larger number of cross veins in the supertriangle of 

 both front and hind wings ; (jalapensis intermediate). 



e. The larger number of antenodals and postnodals in both 

 front and hind wings; (jalapensis resembles mutata}. 



f. The more proximal origin of M, a ; (jalapensis resembles 

 multicolor') . 



4. In mutata the more distal position of the arculus in terms 

 of its relation to antenodal crossveins ; (jalapensis intermediate, 

 resembling mutata') .
