and occasionally this part of the band is finely cut off from 

 both upper and lower portions. (Plate 68, Figs. 7, 8.) 



The caterpillar is yellowish green, merging into pinkish on 

 the sides ; the pink is edged below with black, and this is 

 followed by a dark olive stripe ; rings 1-3 and 10-12 are 

 wrinkled, whilst all the others are ridged across the back and 

 along the sides. It feeds, in August and September, on the 

 unripe seeds of meadow-rue {Thalictrtim flavum)^ also on 

 T. mijtus, and, according to Barrett, on old withered leaves 

 of columbine. 



The moth is out in July, occasionally at the end of June, 

 and occurs locally in " Fenland." 



Doubleday introduced it as British in the Zoologist ior 1848. 

 He there states, "A single example of this pretty species was 

 obtained last season near Peterborough, but I believe it was 

 not in very good condition. A splendid female was sent to 

 me from the same neighbourhood this week (July 15, 1848)." 



In 1853 and 1854 the species was discovered in the fens of 

 Huntingdonshire and Cambridgeshire. Later it was found to 

 inhabit the fens of Norfolk and Suffolk. It is still obtained in 

 the Cambridge fens from Bottisham to Chatteris. Outside 

 " Fenland " it has been recorded from Worcestershire (Bewdley 

 Forest) and Warwickshire (Rugby). 



The range abroad extends to Amurland.

The general colour of the fore wings of this species (Plate 68, 

 Figs. 1-4) is greyish green, with more or less of rosy suffusion ; 

 the basal patch and central band are darker green, and the 

 latter is outwardly edged with whitish below the front margin, 

 and towards the inner margin. The female has rather more 

 ample wings, and is generally of a darker hue, but in both 

 sexes the basal patch and central band are blackish ; the hind
