Psyche 
[June- Sept. 
ment is shown in Plate VI Figure 4. Hairs i and iii lie at 
the anterior edge of the segment in a position more anterior 
than the spiracle, iv is posterior to the spiracle and v ventral 
to it. ii, iv, vi, vii, and viii lie in a line along the posterior 
edge of the segment. The hairs do not arise from conspicu- 
ous scleritized areas as in the preceding species. Legs same 
color as body. Spiracles with brown rims. Crochets uni- 
ordinal forming an elipse. 
Second Instar. Head height .5 mm. ; head width .575 mm. 
Head smooth, clear chalcedony yellow. The spines and the 
region of the ocelli are dark brown to black. Plate V Figure 
2 shows the head spines and the distribution of the hairs. 
Body 2.5 to 3 mm. long. Chalcedony yellow. Covered with 
large branched spines. Green from gut visible. Legs and 
spiracles same as in previous instar. 
Third Instar. Head height .7 mm. ; head width .9 mm. 
Similar to second instar. Head spines longer and more con- 
spicuous (Plate VI Figure 11). Body 5 mm. long. Shiny 
empire green. Spines conspicuously black. Dsitribution of 
spines same as in previous instars. 
Fourth Instar. Head height 1 mm. ; head width 1.2 mm. 
Head similar to previous instars. Lateral and ventral areas 
slightly suffused with green. Body 6 mm. long. Same 
color as before. Spines larger. Large branched substig- 
matal spines occur on all but the prothoracic segment. Here 
there is a prominent prespiracular spine (Plate VI Figure 
5). Suprastigmatal branched spines occur on all segments. 
Those on the prothoracic and mesothoracic segments are 
more postspiracular in position. Branched para-dorsal 
spines occur on all but the first thoracic segment. The para- 
dorsal spine on the second thoracic segment is much reduced 
(Plate VI Figure 8) . Mid-dorsal spines are found on all the 
abdominal segments. The surface of the body is finely 
rugose. The rugosities are deep maroon in color against a 
yellowish surface background. The green color of the 
body is due in great part to the color in the viscera. Legs 
same color as body. Spiracles with black rims. 
Eggs laid July 8 hatched July 12, four days later. The 
first instar required two days with moulting taking place 
July 14. The second instar required three days with moults
