SCOPULA FERRUGALIS. 



Plate CLV, fig. 4. 



I have again to thank my good friend Mr. William 

 R. Jeffrey, of Ashford, and this time for a twofold 

 kindness ; he has enabled me to identify a larva which 

 I figured, but could not rear, in 1867, and also to give 

 the economy of a species which, common enough 

 sometimes in the imago, has hitherto remained un- 

 described in its preparatory stages. 



The larva I had in 1867 was found on some sea- 

 shore plant gathered for another larva, and not de- 

 tected at the time of gathering, so I could not at 

 that time follow up the search ; but on the 27th of 

 September, 1876, Mr. Jeffrey found exactly such 

 another larva at Folkestone, feeding on Eiipatorium 

 cannabinum ; this became full-fed and spun up on the 

 7th of October, not, as I expected, among its food- 

 plant, but at the top of its cage, which was protected 

 with a double covering of grenadine first, and over 

 that of fine cambric ; the larva made a hole through 

 the grenadine, and, crawling between the two cover- 

 ings, cut through the cambric in a horseshoe curve 

 with about five-eighths inch radius, and drawing this 

 partially detached portion together with silk, fixed it
