4:8 BOLETOBIA FULIGINARIA. 
seventh, and eighth, which are not only longer but 
more plump at the sides, being deeply wrinkled only 
at the ends, while the others have their deep transverse 
wrinkles farther apart. 
In colour its soft dark skin reminds one of some of 
the Inthosixe ; it is of a sooty grey-brown colour, very 
dark, approaching to blackness, but this is relieved by 
a number of fine longitudinal streaks of brownish- 
erey along the sides, and on the back by two lines of 
this colour enclosing the contracting and expanding 
blackish dorsal lines, and by subdorsal markings of 
velvety black, consisting of a thick oblong dash on 
either side in that region, about midway on each 
segment, followed close beneath by a fine short streak 
of brownish-grey ; the blackish-brown head is of dull 
dark colour hke that of the body, and similarly marked 
a little with the grey-coloured streaks, but fainter ; the 
belly is entirely brownish-grey or leaden-grey, softer 
and smoother than elsewhere; the anterior pair of 
tubercular round warts are smaller than the second 
pair of each trapezoid, and are of brownish-erey colour 
and shehtly glistening, but the second or hinder pair 
of each trapezoid are larger and of bright ochreous- 
yellow, which “still further relieves and ornaments 
the blackish ground colour; these ochreous-yellow 
warts project and glisten, and also occur on each side. 
of the segments in threes, the largest like those on the 
back occur near the beginning of a segment, the next 
size smaller about the middle, and the smallest lower 
and further back; besides these there is a small grey 
olistening one, and below this occurs the small black 
round spiracle ; each wart emits a fine hair, though in 
the example I had many of these had been broken off 
and reduced to bristly stumps. 
The larva is a veritable geometer in its mode of 
progression. (William Buckler, 1882; Note Book IV, 
p. 186.) 
A few weeks since, my friend Mr. J. Trimmer 
Williams, of Foots Cray, kindly brought for my inspec-
