(4); a yellow subdorsal line on joints 3-12, not quite reaching either 
extremity, the pair unconnected at the ends, but centrally on joints 6-9, 
broadened to the top of the depressed spaces (4) and enclosing in the 
•doisal space a reddish patch on joints 7-8 with salmon-colored margin 
and dark brown latticed ridges. In some examples a reddish mark 
appears on joint 3 between the subdorsal lines. Length, 3.2-4.3 mm. 
Sta S e VI. Structures as before, tail rounded quadrate. Depressed 
spaces large, the latticed ridges closely clear granular. Green, the 
large lateral depressed spaces (4) shaded with yellow. The yellow 
subdorsal lines reach joints 3 and 13, entirely free * or joined by a 
yellow bridge on joints 7 to 9 containing a red spot of varying form, 
corresponding to the variety of the larva. In an example from 
Bellport, Long Island, the spot was cordate, the depression in front, 
pink and edged with a crimson line. In another it was in the 
form of a cross, darker, shaded with brown on the latticed ridges and 
encroaching on the subdorsal line. (See T. pallida , pi. VI, fig. 4.) 
In others the shape was circular, or of the form of the “club” or 
spade as usually depicted on playing cards. There is also another 
spot at the anterior end. In the Bellport larva it was elliptical, cover¬ 
ing joint 3 dorsally, bright red and edged with yellow. In another 
from Fort Lee, N. J., it was shaded with dark brown like the central 
spot. It was present in a larva which lacked the central spot entirely. 
Length, 4.2-6.3 mm. 
Stage VII .—(Plate VI, figs. 5 to 9.) Shape as described. Dorsal 
space of uniform width, scarcely narrowing anteriorly. Skin rather 
regularly coarsely watery granular on the latticed ridges, the depressed 
spaces narrow, finely granular. Color pale yellowish green, pigmented 
in the dorsal and upper half of lateral space, clearer green below. All 
the depressed spaces yellow in the bottom, the largest with glandular 
green centers. Subdorsal line yellow, straight from joint 3 to the tail, 
rather broad. On the anterior edge of joint 3 a red mark, widened 
along the edge, produced backward in the dorsal space more or less. 
The central dorsal red mark is very variable. It may be absent (Plate 
VI, fig. 8) or represented only by a narrow yellow bridge on joint 8 
slightly red tinted (Plate VI, fig. 9). The usual form is a rounded 
cross, reaching on the sides nearly or quite to the lateral depressed 
spaces (4) and in the dorsal space on joints 7 to 9; it may be enlarged 
to a hexagon (Plate VI, fig. 6) or extend in a dorsal band the whole 
* Out of 263 larvae which were found in an oak woods at Yaphank, L. I., only 
■three were entirely without the yellow bridge (Plate VI, fig. 8).
