close to, but on each side of the median line, and situated just be- 
hind each dark dorsal dash. On the sides of each segment from 
the second thoracic to the ninth abdominal segment is a black 
patch, more or less oblong and jagged on the upper edge. The su- 
tures between the segments are not black. The under side of the 
body is blackish. At the base of the abdominal legs is a black 
ring, and another near the planta, and a longitudinal black strip 
down the outside of the leg. 
Sixth stage. — Length 35 mm., Aug. 11. The hairs concealing 
the body are, now uniformly white (Harris referring to the living 
larva, says “of a beautiful white color”), having entirely changed 
their color. The dorsal black lines are now more connected ; the 
three long pencils are pale at base, and black towards, the tip. The 
lateral black spots send two points upwards, and the sutures are 
now black. The head is stained with black on the vertex, and 
along the sutures and around the mouth-parts. The thoracic and 
abdominal legs are black, but the plantse of the abdominal feet are 
pale. Most of the hairs are dark on the distal half, but pale at the 
basal half, and from the black lateral spots arise from two to four 
spindle-shaped black hairs ; also several others which stand out 
from the mass of dull gray hairs, arising from minute tubercles 
along the sides of the body. The legs are hirsute, and the body 
is black beneath. 
Recapitulation. — 1. No glandular hairs, and in stage I, the body 
is already covered with long woolly soft hairs. 
2. In the third stage appear the dorsal black stripe, and a sin- 
gle black pencil on the eighth uromere (abdominal segment) . 
3. The two other black thoracic pencils appear in stage IV. 
4. The hairs become yellow, and the pencils bicolored, while the 
lateral black spots appear in stage V. 
5. The last stage (VI) is signalized by an entire change in 
color from ochre yellow to white. 
Length of egg state sixteen to seventeen days ; of first larval 
stage seven days ; stage II, nine days ; stage III, eight to nine 
days ; stage IV, four days ; stage V, four days ; stage VI, nine 
days (Harris) ; prepupal stage three days (Harris) ; pupal stage? 
Harris states that it does not spin a cocoon, but probably enters 
the earth.
