46 APLEOTA ADVENA. 



which had been reared from eggs. They were very 

 lively creatures, greatly averse to light, and very 

 active in crawling and burrowing under their food for 

 shelter. They throve well on Polygonum aviculare, and 

 by the 26th of July were three-quarters of an inch in 

 length ; they were then pale greyish-ochreous on the 

 back, brownish in the middle, through which ran a 

 fine whitish dorsal line enclosed by two black outlines, 

 which were united thrice across the white line within, 

 at the beginning of each segment, suggestive of an 

 irregular chain pattern. The four tubercular spots 

 black and distinct. The sides, belly, and legs darker, 

 of dull olive-brownish, a fine dirty- whitish longitudinal 

 line above the legs, the subdorsal line darker brown, 

 but interrupted near the middle of each segment by a 

 short oblique streak of pale ochreous from the back, a 

 fine, rather obscure darker brown line running mid- 

 way along the side. Head ochreous. 



Early in September they had attained their full 

 growth, being about one inch and five-eighths in length, 

 rather thick and cylindrical, the head, second and 

 anal segments but a trifle smaller. The head shining 

 olive-brown ; on the second segment a blackish-grey 

 plate, rounded behind, through which pass the pale 

 dorsal and subdorsal lines. The ground-colour of 

 the back and sides very pale ochreous ; a diamond- 

 shape of dark grey mottled with olive on each segment, 

 having on its edges the usual four tubercular dots, 

 rather large, and whitish ringed with blackish -grey ; 

 the dorsal line whitish edged with blackish-grey, but 

 more or less suffused with dark grey and olive as it 

 passes through the middle of the diamond-shapes, 

 though distinct at the beginning of each segment. 

 A very short blackish-grey linear mark on the anterior 

 part of each segment on either side. Subdorsal line 

 whitish, outlined with dark grey, and in its course 

 sometimes touching each posterior pair of dorsal dots. 

 The sides are mottled with dark grey and olive, 

 having oblique streaks and a pale line of ochreous
