OPORABIA FILIGRAMMARIA. 



LARVA OF OPORABIA FILIGRAMMARIA. 



" Eggs received from Mr. J. Svvinden, of Sheftield, hatched 

 17th of February, the young larvaB chose for food ^Yillow and 

 sallow— went to earth about 10th of April.'' 



*' In figure this larva is stoutish and smooth, the general 

 colour is rich velvety green ; the belly pale whitish green. 

 Head and second segment shining, with a blackish tinge. 

 On each side of the dorsal vessel is a line of paler yellowish 

 green ; the subdorsal and spiracular lines are sulphur yellow, 

 the latter being the more distinct, and between them is a faint 

 interrupted yellowish line. On the back of each segment 

 the tubercles appear distinctly as minute yellow dots. Seg- 

 mental divisions orange yellow. Spiracles yellov/, and be- 

 tween them and the region of the belly are a few freckles." 

 Mr. Hellins adds — " Three or four years ago I bred a moth

 to the form of Oporahia which INIr. Weaver used to take in 

 Scotland, and which he is not sure is the same species as 

 the Sheffield insect : I regret now that I did not take any
