BOARMID.E-HAIJA. 383 



Larva stout, bristly, the usual spots raised, the incisions 

 of the segments well marked, otherwise moderately cylin- 

 drical ; head lead-coloured and streaked with black ; colour 

 of the body yellowish-green or some darker shade to bluish- 

 green, violet-brown, purple-brown, or leaden-brown ; dorsal 

 line white, double, both duplicates very slender ; sub-dorsal 

 lines thread-like, waved, white; spiracular stripe broad, 

 yellow, rather extended into a blotch in the middle of each 

 segment ; usual raised spots black and conspicuous, each 

 furnished with a short bristle; uudersurface yellow-green 

 or deep green, with two conspicuous, yellowish or white, 

 longitudinal lines ; legs black ; prolegs dull brownish-black. 

 Sometimes the slender longitudinal lines are smoky-black 

 instead of white. The green individuals usually become 

 reddish-brown just before entering the pupa state. 



April to June on gooseberry, currant — especially red- 

 currant — and other species of Bibcs ; feeding at night on the 

 younger shoots, and resting by day on the undersides or 

 petioles of leaves. Especially attached to gooseberry or 

 currant bushes which are trained against a wall, sometimes 

 stripping these of their leaves, while bushes standing in open 

 ground are comparatively neglected. Very timid and sensi- 

 tive, dropping instantly when touched, and remaining sus- 

 pended by a thread. Dr. A. G. Butler has noted that this 

 larva is distasteful to frogs. 



Pupa moderately stout, anal extremity with a single ter- 

 minal bristle ; colour red-brown or blackish-brown. Sub- 

 terranean, not enclosed in a cocoon. (0. Penn.) 



The winter is passed in the egg-state. 



The moth hides during the day in gooseberry and currant 

 bushes, or sits on a wall in their vicinity, and is easily dis- 

 turbed, flying quickly about the bushes to a similar hiding- 

 place. At dusk it is lively and active. From the nature of 

 its food-plants it is almost confined to gardens, and is in 

 them often very common ; and its larva destructive, stripping
