 dots. These dots are entirely absent from the costal stripe, but on all 

 other white lines the black dots are sprinkled sparsely over the white ; 

 on veins 2. 3, and 4 the black dots follow the veins to cell. There is 

 lit) trace of a subterminal line, and all of the white stripes extend 



directly to the terminal line, 

 which is cream white, edged on 

 either side with a fine brown 

 line; beyond this the cilia is 

 white at base and outwardly 

 speckled with gray and brown. 



Hind wing above cream white, 

 lightly speckled outwardly with 

 pale brown; underside white. 

 Underside fore wing pale ochre-

The venation of this species, as shown by fig. 5, agrees better with 

 Fernald's figure of />. saccharalis 

 Fabricius" than with Hampson's fig- 

 ure of saccharalis? The majority of 

 Hampson's palpal figures in this revi- 

 sion are misleading, as they show the 

 terminal joint as though it were differ- 

 ently scaled than the median joint. FlG - 14-— Head and palpi of dia-

I his is scarcely ever the case in the 



Crambinse. The long overlapping scales of the median joint entirely 

 hide the junction with the apical and usually the same scaling extends 

 to the apex. These characters in this species are shown by fig. 14.
