BOARMID.-E—LIGDIA. 273 



nients five, six, and seven dark brown, followed by smaller 

 spots on the hinder segments ; the head also has a dark 

 brown spot on each lobe. 



June and the beginning of July, and, as a second genera- 

 tion, in August, September, and even October ; on spindle 

 {Euonymus curopmis), feeding at night, but remaining during 

 the day upon its food-plant, to the twigs of which it bears a 

 close resemblance ; if disturbed, it drops and feigns death. 



Pupa thickest in the middle, the hinder portions of the 

 wing-covers being thickened and swollen, almost bulbous, 

 certainly quite corpulent ; eye-covers also very prominent, 

 and mouth organs filled out, leaving a hollow just below ; 

 antenna-cases so sculptured as to appear beaded ; abdominal 

 segments rapidly tapering, very faintly punctured over a 

 broad surface, the smooth hind band of each segment 

 narrow; cremaster a conical spike, tipped with several 

 minute hooked bristles ; eye-covers black ; wing-covers 

 smooth and shining, pitchy black; remaining portions 

 shining dark red-brown. In a slight cocoon of fine silk, in 

 the earth. 



The winter is passed in this condition. 



The moth sits during the day among the leaves of its food- 

 plant, and may easily be disturbed, when it flies quickly to a 

 similar hiding-place ; its natural flight is at dusk and in the 

 night, when it will come to a strong light. Common in lanes 

 where spindle grows in the hedges, also in the margins of 

 woods, and probably anywhere about its food-plant, but not 

 found very far away from it. In this manner fairly common 

 in all the Southern and South-Western Counties to Worces- 

 tershire, and the Eastern to Norfolk; much less frequent 

 in the Midlands, but recorded very locally in Leicestershire 

 and Warwickshire, and rarely in Derbyshire ; also in York- 

 shire occasionally, in Lancashire rarely, and in Westmore- 

 land. In Wales the only locality in which I find it recorded 

 is Dolgelly; there is one doubtful record in the extreme
