NOTES ON THE PUPA OF CETA FLORIDANA. 
PLATE VI. 
By T. A. Chapman, M. D. 
Length, 13 millimeters; width, 2^ millimeters. Tolerably uniform 
width to the fourth abdominal segment, thence tapering finally to 
extremity. 
Color .—Deep sepia, nearly black. A pale nankeen coloring in a 
broad dorsal stripe, along all the abdominal segments, extending out¬ 
wards as far as the anterior trapezoidal tubercles, and having a narrow 
double line of the dark sepia or black color down its centre; traces of a 
similar coloring in a narrow supra and another infra-spiracular line. 
The same color surrounds the marginal tubercles and at pitted 
markings in the situation of the third and fourth ventral prolegs. 
Similar color on the front of the headpiece and a narrow line on 
each side of the prothorax and a broad patch in the centre of the meso- 
thorax, ventral line of fifth and sixth abdominal segments also paler. 
Dehiscence is by complete removal of front headpiece, by splitting 
down the back of the prothoracic segment and two-thirds of the meso- 
thoracic. 
The antennae separate from wings two-thirds of the way down and 
slightly from leg cases which also open a little at anterior ends; they 
remain attached together below and also to wings; eye pieces remain 
in situ. 
The two portions of prothorax somewhat separated from mesothorax, 
but attached by delicate membrane, and show fine radiating structure 
of first spiracle. (Plate VI, Fig. 3.) 
Structure .—There is no posterior headpiece; the separated front 
piece is roughly hexagonal, the two sides being hollowed to receive the 
ends of the antennae; and in the pale area here there are on each side 
two spines or hairs (antennae-basal hairs?), the inner one curled at the 
ends into a circle and a-half. In face piece the central portion above 
has three hair points on each side and terminates in a rounded projec¬ 
tion (labrum); beneath from each side are two rounded lappets (man¬ 
dibles); these occupy about the central third of the face (Plate VI, Fig. 1); 
at the summit of the first pair of legs between the eyes and antennae is 
a small separate portion (max. palp.). The maxillae, second legs and 
antennae reach to the extremity of the wings close to the hind margin of 
the fourth abdominal segment, to which they are fixed.
