COREMIA PROPUGNATA. 69 



The young larvae appeared on the 23rd of June, 

 were slender, dark olive-brown, the head brownish. 



They fed up rapidly on young cabbage leaves, and 

 by the middle of July were full-grown. 



Length of full-grown larva about an inch, and of 

 moderate bulk in proportion ; the head has the lobes 

 rounded, and is considerably narrower than the second 

 segment ; body rounded above and below, but the two 

 portions are distinctly divided by the skin at the sides 

 forming a raised lateral ridge ; it is of tolerably uni- 

 form width, tapering only a little towards the head ; 

 the segments are distinctly divided, and the skin has 

 a somewhat tough appearance. 



Ground colour dingy ochreous, but (except on the 

 last four or five segments) is almost entirely covered 

 with dark, dull smoke-colour; in some specimens 

 this dark shade is nearly black, whilst in others a 

 very dark green tint is observable ; head glossy, pale 

 brown, with darker brown spots; dorsal line darker 

 green, paler on the posterior segments ; subdorsal 

 lines rather waved, grey ; there is also an indistinct 

 finer grey line between the subdorsal and spiracular 

 regions, but there are no perceptible spiracular lines. 

 On the anterior of each segment and situated ofi the 

 dorsal line is a conspicuous rather large black spot, 

 and this spot is generally preceded by an equally 

 conspicuous paler mark, of various tints in different 

 specimens, in some being pink, in others grey or 

 yellowish ; spiracles distinct, black, the raised tuber- 

 cles grey. 



Ventral surface dull ochreous or (in some specimens) 

 pinkish ; it has a fine smoke-coloured central line 

 enclosed in a band of the ground colour, outside of 

 which, on each side, is an olive band, bordered 

 outwardly with a fine smoky line, and there are faint 

 indications of one or two other waved lines between 

 this and the spiracular ridges ; on each side, too, is a 

 double series of black dots of two sizes, a large one 

 being in front, followed by a smaller one.
