APLECTA HERBIDA. 37 



increasing its depth ; along the side is a similar series 

 of more elongate and narrower diamonds of freckles, 

 followed below by a rather thin blackish line on which 

 the white spiracles delicately edged with black are 

 seen. Beneath the spiracles is the usual stripe of pale 

 ochreous. On the head is a black brown streak down 

 each lobe, and the spaces between the lines on the 

 second segment are filled with rather darker brown 

 than the rest of the back. The lateral breadth of the 

 junction of the twelfth and thirteenth segments is the 

 widest part of the larva ; otherwise, with the exception 

 of the head and second segment being a little tapered, 

 the rest of the body is cylindrical and of uniform sub- 

 stance. 



These larvse fed up to full growth in November, two 

 of them burrowing into the earth on the 17th, and the 

 other two on the [no date given in MS.]. 



The full-grown larva and from its last moult is very 

 much darker brown, indeed for a few days after this 

 moult it is so dark a purplish-brown as to show but 

 little more than the dorsal paler fine line, but with its 

 growth by expansion of skin the slightly paler sub- 

 dorsal fine line also appears, but in an interrupted 

 manner. The ground-colour of the skin is now of a 

 pinkish grey-brown or light purplish-brow 7 n ; this is also 

 the ground-colour of the very shining head, which is 

 broadly streaked with black down the front of each 

 lobe and delicately reticulated at the sides, with a black 

 triangle between the lobes. The second segment has 

 a velvet-like blackish-brown patch on the back through 

 which run the fine dorsal and subdorsal lines ; the 

 last-mentioned is on the next four or five segments 

 invisible from the dense mass of dark blackish purplish- 

 brown freckles that hide the ground-colour, but this 

 begins to appear on the other segments more and 

 more distinctly towards the posterior end of the larva, 

 and it is along those segments where the subdorsal 

 line is best to be seen, and within this line on either 

 side is a blackish purplish-brown wedge mark com-
