36 LEPIDOPTEKA. 



called pale varieties ; sometimes the dark dusting has a 

 distinctly smok^'-brown tint ; in others it is so dark a grey 

 that the moth appears almost lead-coloured. Such an 

 example is in the collection of the late Mr. F. Bond. Others, 

 ia Mr. G. T. I'orritt's collection, are strongly tinned with 

 smoky-brown, in ground colour or in dusting. In size there is 

 a good deal of disparity, those of the later broods being often 

 very small, while in Suflolk a form is found, in the summer 

 brood, of quite double the usual size and very pale in colour. 

 On the wing in June, as a second brood, often much more 

 plentifully, in the later portion of July and in August ; and in 

 some seasons casual specimens of a partial third generation 

 may be found in September or October. 



Lauv.v long and slender, tapering toward the head, which 

 is small and rounded, dark brown or reddish-brown with a 

 pale stripe down each lobe ; skin transversely wrinkled ; 

 pale brown ; from the fifth to the tenth segments, on each, 

 is an ill-defined dorsal brown diamond, which often encloses 

 smaller brown outlines of diamond-shaped markings; on the 

 second to the fourth, and on the tenth to the thirteenth, is a 

 grey-edged ochreous dorsal line ; spiracular line blackish, 

 often very conspicuous, but sometimes absent, edged above 

 with whitish-ochreous ; this pale ochreous line is present 

 even when the spiracular dark line is wanting ; the segments 

 where the dorsal line appears have also a paler ochreous sub- 

 dorsal line, broad and edged with pale brown ; on the fifth 

 segment are four black dots, two lateral and conspicuous, 

 two dorsal and minute ; iindersurface pale grey or ochreous, 

 with two waved central black threads, and a pair of black 

 dots at each incision — these spots being frecjuently situated 

 at the termination of oblique blackish dashes. (Chas. Fenn.) 



Among his larvae Mr. Buckler noticed a variety of a pale 

 grey ground colour, in which the dorsal line could be dis- 

 tinctly traced throughout, though but little paler, it was 

 strongly margined at the beginning of each segment with a
