3l8 THE MOTHS OF THE BRITISH ISLES. 



The moth flies from late June to early August, and its range in 

 the British Isles is pretty much as in the last species, but 

 more generally distributed than alsiiics in Ireland. 



Vine's Rustic {Cai-adriua ambigua). 



The fore wings of this species (Plate 151, Fig. 8) are rather 

 greyer than those of the last, and the hind wings are shining 

 white, tinged with greyish brown in the female, especially on 

 the veins. 



Barrett describes the caterpillar as follows : " Plump, 

 cylindrical ; head round, the lobes dark brown, but the face 

 paler ; dorsal region between the subdorsal lines broadly 

 yellowish brown, with slender, delicate, oblique lines on each 

 segment ; dorsal line a row of black dots, one on each segment ; 

 lateral space from the subdorsal lines to the spiracles darker 

 brown or umberous, containing a row of ovate, oblicjue, yellowish 

 spots, each rather raised into a knob by the wrinkling of the 

 skin ; spiracles black ; under surface, legs, and prolegs pale 

 rosy brown, except the anal prolegs, which are brown." It 

 feeds from October to May on dandelion, plantain, chickweed, 

 and other low plants ; also on lettuce and grass. The moth 

 flies in August and September. Sometimes the caterpillars 

 will feed up and attain the moth state the same year in 

 November or December. The species was not known to 

 occur in England until some specimens were taken by Mr. 

 Vine at sugar, near Shoreham, Sussex, in 1879. Since that 

 year it has been taken more or less freely at several places 

 on the south and south-west coast, from Deal, in Kent, to 

 Truro, in Cornwall. 



The Pale Mottled Willow {Caradrina quadriptmctata). 



The black s])ots on the front margin of the fore wings of this 



species i Plate 151, Figs, y, 10) arc pretty constant characters,
