No material difference existed between the two larvaa, excepting that the cap- 

 tured one was rather less bright and distinct in coloui" and markings than the 

 other. The full grown larva is an inch and a-half in length, tapering much 

 to the anal forked extremity, and a little towards the head, which is globular. 

 Ground colour of the back a delicately mottled drab, with longitudinal stripes 

 broadest along the middle segments, viz., a dorsal stripe of oUve-brown, very dark 

 at the beginning of each segment, with a thin edging of brownish-white. Throe 

 stripes along the sub-dorsal region, of which the first is composed of a double nar- 

 row line of yellowish-brown, the second wider, of the mottled ground colour, edged 

 above with paler and below with white, and the third of similar width of dark grey 

 brown, edged above with black. Spiracular stripe broader and of nearly equal 

 width, of pale ochreous-brown, edged both above and below with bi'ownish-white. 

 The spiracles black. Belly and legs drab colour. Head brown, on which the 

 principal stripes of the body are delicately marked with darker brown. —

Description of the lai-va of Acidalia mancunxaia. — At the time that Mr. HelUns sent 

 me two larvae as variations of A. subsericeata, I remember making known to him 

 that they were not the least Hke those of that species sent to me in October, 1862, 

 by Mr. Crewe, nor yet like others I had in April, 1863; for both Mr. Crewe's 

 examples and the last named, although they varied slightly, were all constant to 

 one particular, viz., a pale yellowish or whitish mark on each side of the ninth 

 segment. 



It will be seen by the subjoined description that, from subsericeata, Mancu- 

 niata is more distinct in the larval than in the perfect state even, the character of 

 its markings being entirely different. 



Description. — Larva abont three-quarters of an inch long, tajjering gradually 

 towards the head, which is grey-brown, with a daik brown line on each lobe. 

 Ground colour of the body pale reddish-grey ; dorsal line scarcely paler, very thin, 

 and enclosed by a broad brown line on either side, which gradually widens down to 

 four-fifths of the segments, and then contracts towards the segmental divisions, and 

 at the widest portions on each side is a rather large spot or blotch of blackish- 

 brown. 



The sub-dorsal lines are of grey -brown, very thin and double, with a blackish- 

 brown oblong blotch on them, about the same distance from the end of each 

 segment as those on the dorsal region. 



The last four segments appear paler than the others, as the dorsal line on them 

 is enclosed only by thin brown lines, and the sub-dorsal lines on them also have no 

 dai'k spots, except a slight indication of them on the tenth segment only. 



A blackish-brown line on the spiracular region extends between the tenth and 

 thirteenth segments. 



The full-fed larva was figured on the 15th July, and on the 20th it changed, on 

 the surface of the earth, to a very slender dark blackish-brown papa, the tail of 

 which was turned backwards. 



The moth appeared August 9th. — Id.
