114 THE MOTHS OF THE BRITISH ISLES. 



The rough-looking, long and slender caterpillar is pale greyish, 

 with a black-edged pale line along the middle of the back, the 

 black edging interrupted on rings 4-9 ; on each side of the 

 central line, and lower down along the sides, are other black 

 streaks ; head, notched on the crown, and marked with brown. 



Some eggs laid August 8th, hatched on September ist; the 

 infant caterpillars were long and thread-like, the colour was 

 black, and there was a whitish stripe low down along the sides. 

 They would not feed on knotgrass and other plants offered to 

 them, and I failed to rear them. Moths hav^e, however, been 

 bred, as a second generation, in the autumn from caterpillars 

 reared from the egg, on bramble and knotgrass. 



The moth occurs in July and August on bush-sprinkled 

 heaths, or heathy ground, where it may be disturbed from the 

 herbage in the daytime, or netted as it flies in the evening. 

 South of England from Kent to Dorset ; also in Berkshire, 

 Cheshire (one specimen, Whitegate Heath, 1901, one ab. 

 circellata in Delamere Forest, July, 1903) ; Yorkshire (Thorne 

 Moor, and rather plentiful on Skipton Common in 1900 and 

 subsequent years ; ab. circellata also occurred). 



The Dwarf Cream Wave {Acidalla {Ptychopoda) 



iuterjectaria). 



This moth (Plate 45, Figs. 15, 18) is said to be referable to 

 fuscoveiiosa, Goeze, and as this is an earlier name than inter- 

 jecfaria, Guende, it may have to be adopted. For many years 

 it was known in England as osseata, and was described by 

 Haworth, Stephens, and others, under this name. It is also 

 the dilutaria of some authors, but not of Hiibner. Hiibner's 

 dilutaria is considered by some writers to be the liolosericata 

 of Duponchel, and therefore an earlier name for the species 

 generally known by the latter name.
