Pu;pa. 



Head broad, abdomen slaty grey, velvet-like, deeply 

 ringed. Wing-cases and thorax more or less green. 



Winged viviparous female. 



Head and thorax shining black. The latter with 

 two strong spines. Antennae and legs as in the larva. 

 Abdomen pointed, shining, dark olive green, with ob- 

 scure transverse bars, spinose. Cornicles black. Cauda 

 moderately long, olive green. Wings short, pale, 

 iridescent, finely veined with yellow ; insertions and 

 stigma grey. Rostrum reaches to the third coxsb. 



This species has a great resemblance to A. Jacobceoe, 

 but is larger and more shining. The head and thorax 

 of the winged insect are much less developed in width, 

 and the wing-veins are not so coarse and black. 



Taken abundantly on Bumex acetosa from June to 

 September. In autumn the larva becomes more linear 

 in form, and decidedly greener in hue.
