SERICORID.E—EUDEMIS. 69 



Larva cylindrical, active, dark green, slightly paler 

 beneath ; head very pale brown ; dorsal and anal plates 

 black; legs also black; raised dots green; hairs short. 

 July and a second generation at the end of August and 

 in September ; on Euphorlia parcdias (sea spurge) in the 

 shoots, drawing together the terminal leaves into a bundle, 

 eating the heart completely out and boring down the shoots, 

 forming a chamber much lined with frass in the hollowed 

 space. Also on Enphorhia lucida, E. aqitatim and E. 

 amygdaloidcs. 



Pupa light chestnut-brown; its whole surface shining; 

 ridges of the abdomen very small, with almost imperceptible 

 spines ; cremaster short and broad, furnished with a number 

 of hooked bristles. In a closely constructed, delicate, white, 

 cocoon of papery silk, between two dead leaves of the food 

 plant, or among rubbish. 



The moth is rather sluggish and seldom observed on the 

 wing, yet on a bright sunny afternoon may sometimes be 

 seen flying in a lively manner. Its natural time of flight is 

 towards dusk, and at that time one or two may occasionally 

 be seen buzzing about the spurge, but the great majority of 

 our specimens are reared from the larva state. Its principal 

 locality with ns has been on the Kent coast, especially at 

 Folkestone, whence it has been, I fear, nearly exterminated : 

 it has, however, been found in Savernake Forest, Wilts, and 

 very rarely in Somerset; also in the Malvern district of 

 Worcestershire, at Farrington, Herefordshire (where it has 

 been taken among wood spurge by Dr. Wood), and it is 

 reported, rarely, from Warwickshire by Mr. Bradley and 

 from Bedfordshire by Dr. Sharpin. This is, I think, the 

 extent of its range in these Islands. Abroad it is found 

 over the greater part of Central Europe— Professor Zeller 

 wrote of it as especially plentiful in the valley of the Oder 

 — and in Sicily ; also as a larger variety in Asia Minor.
