Striana Group. 



Dark buttoned, excepting in insidana ; pale striae take the 

 place of vitta. 



The only new name, introduced by Clark, appropriate to this 

 group was one he adopted from Mr. Bond, who had separated 

 and labelled as distinct a series without buttons, but not other- 

 wise distinguishable from striana of Haworth, calling it pi'o- 

 striana. This characteristic is sufficient to distinguish any 

 specimen without further description. 



Insidana, Curt., Desv. — Comes very near to striana, Haw., 

 but it is a darker insect, with large distinct pale cream button, 

 the bone-coloured striatious run to the hind margin, and they 

 almost constitute a distinct vitta. Superficially it thus resembles 

 subvittana, Steph. 



Striana, of Haworth, was doubtless named from the vitta 

 being broken up into ashy coloured lines, which are generally 

 three in number. The first along the inner margin, another 

 from the base following the line of the fold, and a third immedi- 

 ately above the second, which does not begin until the first of 

 the minute tufts before the button. The space between the first 

 and second is more or less filled in with ashy grey, and the chief 

 differences between moths of the striana form occur here, as 

 occasionally from two to five subsidiary diverging hues, starting 

 from the third line and below the button, spread fan-like out- 

 wards to the end of the wing ; but it is not desirable to name 

 any of these. 



Desvigne's plan of placing forms of cristana in separate 

 groups, although far from satisfactory, is preferable to Double- 

 day's attempt at a natural sequence. I have followed the former 

 plan, but no effort has been made to place the groups seriatim ;
