100 EUBOLIA LINEOLATA. 



whereas the spring flight has been eight months in 

 the pupa, having passed the winter in that state, the 

 summer flight of moths comes out after little more 

 than a fortnight's stay in the pupa. 



The food on which I have taken the larva at large is 

 Galium verum, and I have reared it on G. saxatile, but 

 it does not seem to care so much for G. mollugo. I 

 have noticed that the moth is fond of resting on the 

 coarse grasses which grow in its sandy habitat near 

 the sea, where I have been accustomed to take it. 



The egg is rather a long oval in outline, the broader 

 end being also thicker than the other ; it is flattened, 

 but is deposited almost upright on its smaller end, in 

 little clusters; the shell is polished, but not brightly, 

 and is very faintly reticulated all over ; the colour is 

 at first pale straw, soon becoming almost orange, and 

 at last pale brownish-ochreous. 



The larva, when first hatched, is yellowish-ochreous 

 in colour, with a faint, dusky, suffused stripe down 

 the back, and a subdorsal line of the same, the head 

 deeper yellow, the usual dots small and black ; when 

 it begins to feed, the food shows dull green in the 

 middle of the body, the rest remaining still ochreous, 

 but it soon becomes pale greyish-green all over; when 

 rather less than half-grown it is greyish-green above, 

 with a dark green dorsal line, and a brownish stripe 

 above the spiracles, all below being yellowish-green or 

 whitish-green. 



When full-grown the length is about seven-eighths 

 of an inch, the figure slender, uniform in bulk when 

 viewed from above, but when viewed sideways taper- 

 ing towards each extremity ; the head is nearly as 

 wide as the second segment, somewhat flattened, but 

 the lobes with rounded outline. The colour is variable 

 above, the back being dull pink, lighter or deeper in 

 tint, warm brown or olive-brown ; the dorsal line is 

 dark brown or blackish-green, sometimes bordered 

 with yellowish-pink ; the fine subdorsal line is 

 yellowish on the second, third, eleventh, twelfth,
