48 LEPIDOPTERA. 



Variable in size ; moreover, the ordinary form abroad 

 seems to have more dusting of black scales, especially over 

 the costal area, which consequently is not so white, nor the 

 general appearance quite so silky. 



On the wing from June till August. 



Lakva obese, cylindrical, almost uniform in width ; head 

 small, narrower than the second segment, its lobes rounded, 

 dark brown, darkest on the upper part of the lobes, polished ; 

 dorsal plate also polished, yellow-brown, with a distinct, 

 intensely black border behind ; ground colour yellowish- 

 wreen, varying in shade; markings all purple and con- 

 spicuously defined; dorsal stripe rather irregular; in the 

 sub-dorsal region is a pretty series of large round marks, 

 one on each segment, sometimes forming rings ; below 

 these along the spiracular region are other marks, usually 

 three on each segment — one situate over two others — ventral 

 surface and pi-olegs very pale green, legs glossy black.

Augtist to October on wild camomile — Antlnnnls, Matvi- 

 cfiriii, and Fi/rethriim inodonrm, feeding across the flower- 

 disk, on which it causes the florets to appear rough, eating 

 the seeds ; also feeding in flower heads of Aster, Hicrariam 

 umhdlatam, and according to A. Schmid on G^miphdium, 

 Senecio, Chrymcoinu, Ciirliiia, Solidngo, and other composites, 

 to which Zeller adds Jusionr. riiontaim. Hire it appears 

 greatly to prefer the " camomiles." 



Pupa slender, light brown : iqiparently not more fully 

 described. In a thick cocoon of greenish-grey silk, in 

 which it passes the winter as a larva, pupating in the 

 spring. 



The moth bides among the thick growth of its food- 

 plants, and is not to be aroused in the day-time, unless the

 distance to hide again ; Init very soon alter sunset, and
