segment and the tendency to a hump of the 12th. It no longer 
sits in ? shape except occasionally when alarmed, it is wonder- 
fully uniform in width and bulk from end to end, the front 
few segments being only a little smaller, and behind, it tapers 
only at the 13th segment. Each segment is full and cushiony, 
and (except the head) each has the yellow lozenge on back, 
so as clearly to demonstrate not only the 13th but a 14th 
segment. 
The yellow plates include both trapezoidals, of which the 
anterior has a small black bristle, the posterior the clavate 
hairs ; on each segment the yellow lozenge has a special out- 
line, those of 5th to loth have rounded ends and front and 
back edge parallel. On the nth it is square with a minute 
notch at the side, on the 12th nearly square, on the 13th curved, 
with the concavity forwards, and ends square, the 14th lunated 
with only two short hairs ; on the second, it is broader but of 
similar shape, on the third, the front edge is produced to a 
blunt angle in the dorsal line, and, on the 4th, the same, but 
with the addition of a corresponding notch behind. 
The yellow lozenges rise a little above the surface as if laid 
on, on the 3rd and 4th they include the supra-spiracular 
tubercle ; the anterior and posterior edges of each lozenge 
paler, in a few specimens nearly white. Each lozenge has 
sundry wrinkles disposed in relation to a deep groove that 
crosses it transversely about the middle, and has several dark 
spots or lines in its course. 
This groove, with its ends curving forwards and a shallow 
depression in the dorsal line, mark the divisions between 
the tubercles. On the 3rd and 4th segments there are no 
transverse grooves, the original disposition of the tubercles 
being different, on each of them the six hairs of the original 
tubercles exist but are very short, none being clavate, a sur- 
vival of the circumstance of these being originally pale seg- 
ments. Similarly, ii has no clavate hair, is lower dorsally 
than the other segments, the anterior trapezoidal has a very 
minute hair, and that of the posterior trapezoidal is only as 
large as that of the anterior trapezoidals of the other segments. 
Segment 2 has two clavate hairs, which always lie closely 
together at their ends, this segment still has a double row of 
tubercular hairs, and illustrates that this segment is, dorsally, 
an equivalent for two segments, what the second equivalent is 
ventrally is not so plain ; it appears to have a pair of prolegs 
like 3 or 4, whether the appendages of the other half of this
