This species, Ihe larva of which, as is well known, feeds in the 

 rootstocks of Senecio jacohcca, normally has, on the jioslerior half of 

 tlie cosla of the fore-wing, eight sliort narrow white streaks, arranged 

 in four pairs, the two streaks of each pair being separated from one 

 another by a narrow dark brown streak, and each pair being separated 

 from the next by a dark brown bar. In Haworth's type specimen of 

 costipunctana, however, the white costal streaks are broader ; the 

 narrow dark streak that separates the two white streaks of each })air 

 does not disajipear, but the dark bar between each two pairs is itself 

 reduced to a streak. Llence the white streaks have quite lost the 

 appearance of b(>ing arranged together in pairs, and are seen as eight 

 separate white costal streaks or s))ots, alternating with seven dark 

 ones, these latter representing the four dark streaks that normally 

 separate the streaks of each pair, together with the three dark bars
