LORQUINIA 
Aug. 6, 9:15 A. M. Larva has increased to 6- mm. long. 
Aug. 7, 9:15 A. M. larva has increased to 7 mm. long. I can 
distinctly see a row of yellow spots on both sides, right over the legs 
and prolegs. They are easily distinguished from the purple color of 
the skin. The anterior part is now of the same thickness as the 
posterior, having thus reduced in size. 
Aug. 8, 5 :30 A. M. Larva has increased to 8 mm. long. 
Aug. 9, 10 A. M. Larva has increased to 10 mm. long. It is 
now 2 mm. in width. It eats a leaf ramification of the Anise, which 
is 10 mm. long and ^ mm. wide, in 25 seconds. This is certainly 
astounding when compared to the eating powers of the higher ani- 
mals. I see that the tubercles along the sides and back are covered 
with hairs, quite small and well separated. The whitish point on the 
dorsal part of the larva is divided and on the back proper there is no 
white spot. 
Aug. 10, 10:45 A. Larva has increased to 12 mm. long. 
Aug. 11, 9:15 A. M. Larva has increased to 13 mm. long. 
There is a row of white spcvs on either side, right under the row of 
yellow spots, on the sides of the prolegs. The head is banded with 
two black lines, forming an angle at the apex, and having a spot just 
over the mouth parts inclosed hy the first two lines. 
Aug. 12, 9:10 A. M. Larva has increased to 17 mm. long. 
When alarmed it suddenly jerks and throws out two orange yellow 
filaments, one longer than the other, placed just behind its head. It 
has now done this for about five days. The filaments now measure 2 
and 3 mm. respectively. The larva now measures 4 mm. across the 
body. 
Aug. 13. 9:45 A. M. I arva has increased to 21 mm. long. 
Aug. 14, 8 :45 A. M. Larva has increased to 22 mm. long. 
Aug. 15, 2:30 P. M. Larva has increased to 23 mm. long. It 
has radically changed color. The shed skin lies in the leaves of the 
Anise. The new colors are : head same as last described excepting 
a small black spot on either side of the angular lines. Then, begin- 
ning with the thorax and going backward, there is a yellow ring, 
then a black ring, light blue ring, black ring, yellow ring, black ring 
with six orange spots, blue ring, black ring, blue ring, black with 
orange spots, etc. The prolegs have two black spots on the outside 
and the true legs have three black spots on the outside. The abdomen 
is white with black spots in the middle at intervals. 
Aug. 16, 10:20 A. M. Larva has increased to 25 mm. long. 1 
can now readily perceive a strong and disagreeable odor when the 
larva throws out its filaments. This is its manner of eating. It 
chooses a twig of a leaf, clutches it with its six true legs, or only 
four of them, clutches some other leayes with its prolegs, goes to the 
tip of the chosen twig and starts eating down, wiggling its head up 
and down, until it gets to where the twig is attached to the stem.
