sitriple. The hair is thin, nowhere concealing the body, blaclv and brown 
mixed. 
Sixth stage. — Female larvae undergo this additional stage with no 
change in markings. Width of head 6.5 mm. 
Cocoon. — Composed of a few threads drawing together loose material. 
Pupa. — Slightly flattened ventrally, tapering posteriorly, cases promi- 
nent. Tufts of soft spreading brown hairs represent the larval warts 
and also occur on the slight leg prominences. Cremaster flattened, with 
two bunches of short hooks. Color brownish black, cases faintly 
creased, not shiny. Length 15-25 mm. ; width 5-10 mm. 
I consider tlie genus Macrnrocam])a to be well defined ; the 
accessory cell is absent in all the specimens accessible to me. In 
this respect, it approaches Cerura, which also lacks the accessory 
cell, except in occasional specimens of C. occidental is.

Egg. — Flattened, hemisplierical, quite flat on the base, the shell thin 
and translucent, covered with shallow hexagonal depressions of uniform 
size (seen under a i-inch objective). Diameter 1.3 mm. Deposited 
singly on the under side of a leaf. The larva hatches by eating a large 
hole near the vertex. 
First larval stage. — Head cordate, higher than wide, flat in front; 
smooth, shining, pale brownish yellow, with a brown line on each side 
from the jaw to vertex of head, the two united at the top ; width 0.7 mm. 
Body cylindrical, annulated, shining; on the vertex of joint 2 (first 
thoracic segment) a pair of divergent fleshy processes, each tipped with 
a hair and about 0.4 mm. long, colored black at tip and red at base. 
Anal feet prolonged into a pair of tails flve millimeters long, setose, pale 
brown at base, the outer half black with a broad white ring. Body pale 
greenish, asubobsolete brown dorsal band, emphasized on joints 5, 7, and 
11. A very obscure yellow subdorsal band. 
Second stage. — Head conoidal in outline, higher tlian wide, rounded, 
not depressed at vertex, flat in front; pale yellowish green, mouth parts 
brownish, ocelli black; width 1.1 mm. Body as before, the marks rather 
more pronounced. Cervical horns sliorter, pale at base, red at tip,
