May to .September, apparently in three successive genera- 

 tions. 



Larva active and restless ; pale yellow or dull white with 

 the dorsal vessel faintly visible, except in the ninth segment 

 where it is broad and distinct ; head light brown, margined 

 with black at the back ; jaws dark brown ; dorsal plate very 

 pale horn colour with two black dots on the posterior margin; 

 anal jalate horn colour ; feet grey. As it reaches full growth 

 it becomes tinged with pink. 



June, August, and October to April or May; in three genera- 

 tions on Pijrcthniiii iiiodori!,i/i(corn feverfewj, burrowing in the 

 stems and shoots and eating the pith between two joints or in 

 the later broods feeding in the flower or seed-head. Also in 

 Anthcmls rotuhi, Matricaria chaiiwraiUa, and So/ir/arfo 

 ■virgaurra. Assuming the pupa state in the larval habita- 

 tion. It is a curious circumstance that in woods the golden- 

 rod seems to be exclusively chosen, while on railway-banks 

 and such exposed situations the species cf chamomile are 

 conspicuously favoured. 



This species is easilj' disturbed and induced to fly in the 

 •daytime, especially in the afternoon. It does not sit exclu- 

 sively on its food-plants, but takes readily to any cover close 

 by ; at sunset flies freely of its own accord and continues 

 into the night coming sometimes to a strong light. Par- 

 ticularly fond of railway banks, where among chamomile it 

 is often abundant. 



First noticed as British, under the name of E. hejidcniawt, 

 in the "Entomologists' Annual''' for 1869, by my colleague, 

 Mr. R. McLachlan. Since that time it has, I think, very 

 greatly increased here in numbers, and in range of localities. 

 It is not scarce in the outskirts of London especially on rail- 

 way banks, and has even been found in waste land at the back 

 ■of the Natural History Museum at South Kensington. 

 Elsewhere frequent in Middlesex, Surrey, Kent, Sussex, 

 Hants, Dorset, Berks, Essex, Oxfordshire, Somerset,
