Notes in 1887 upon lepidopterous larve, dc. 549 
occur in Deilephila ewphorbie. The habit did not take 
place in the earlier stages of S. convolvuli. When 
irritated, the mature larve curled up and remained in 
this position for a very long time. 
They were fond of drinking the drops of water which 
were sometimes introduced on the food-plant. 
They freely ate the brown and withered leaves which 
were occasionally introduced when the plant became 
frost-bitten in late autumn. 
The antenne were in a state of continual and rapid 
vibration. 
The Sphinx attitude was never observed in the large 
larve. This fact is, doubtless, due to the usual 
horizontal position upon a food-plant, which chiefly 
creeps along the ground. This will be again alluded to 
in discussing the significance of the attitude. 
Lengths of mature larve and times at which they ceased 
to feed. Seven out of the fourteen larve were preserved 
at various times in the last stage. 
Oct. 29th.— Division III.: 3 out of the 4 larve had 
been preserved, the remaining larva No. (8) in the table 
of comparison, probably ceased feeding Oct. 27th, or 
even a day or two earlier; it had certainly ceased 
feeding on Oct. 28th. This larva was 73.0 mm. long 
when extended in walking, but it was somewhat con- 
tracted by this time. 
Division I.: 2 out of the 5 larvee (Nos. (1) and (6) in 
the table) had been preserved; of the remainder, the 
lightest larva (No. (4)) ceased feeding at about the same 
time as the larva mentioned above. The 2 larve still 
feeding at this date were 72°0 mm. when at rest, about 
76°0 mm. when extended in walking. 
Division II.: Of the 3 larvae, 1 ceased feeding pro- 
bably on Oct. 28th; 1 of the 2 still feeding was 75:0 
mm. when moderately extended at rest. 
Division IV.: Both of these larve were preserved. 
Oct. 80th.— Division I.: 1 larva still feeding, 1 walk- 
ing about hurriedly as if preparing for burying; the 
former, 75° mm. in length when comfortably extended, © 
the latter rather larger, but in a somewhat contracted 
state. Both larve, if stretched, would reach 80°0 m.m. 
Oct. 31st.—Dwision II.: Another larva had ceased 
feeding at this date ; the larva still feeding was 85°0m.m. — 
long when extended, and was thus considerably larger
