348 LEPIDOPTERA. 



reddish-yellow, with segmental divisions redder on the back ; 

 anal segment purplish ; head very small, masked and tucked 

 down, pale brownish or greyish, with the usual position of the 

 mouth brown ; no mouth-organs nor antennae ; legs merely in- 

 dicated by minute, slender, glassy, yellow, jointed points 

 without claws — mere papillte, apparently without motion or 

 functions — body thick and rounded, but with the segments 

 distinctly visible as in a larva ; tapering off rapidly at the 

 eleventh and twelfth, and with the thirteenth segment small 

 bluntly terminated, except a small point or ovipositor-case pro- 

 jecting from the centre. This portion of the body has a ver- 

 micular motion, otherwise the creature seems quite inert. On 

 emerging from the pupa the moth here described at once forced 

 itself out of the case and fell prone to the bottom of the box 

 in which it was confined. This, the only living female specimen 

 which I have seen, was obtained by Mr. F. G. Whittle, who 

 found the case during a protracted search for that of the 

 following species. Preserved specimens, furnished by Mr. 

 Webb and Mr. E. R. Bankes, are contracted, very short, 

 deeply ridged, with the segments sharply edged and ovipositor- 

 case prominent ; reddish-brown, with the head darker. 



The only variation to which the male of this species seems 

 liable is in size, and perhaps in intensity of blackness, though 

 that depends mainly upon its freshness when captured, or 

 the degree of fading to which it may have been subjected 

 either alive in sunshine or in the cabinet. Specimens, 

 faded very brown, and partially denuded, appear to have been 

 placed in a few collections under the name oi marfjivcnicircUa. 

 Another form, deep black and of larger size, reaching occasion- 

 ally to nearly three-quarters of an inch in expanse, and said 

 to be confined to marshy places, has been thought distinct, 

 but apparently without cause. All intermediate gradations 

 occur.
