by the network are of various shapes, triangles predominate though 

 crude squares and diamonds are present especially around the 

 micropyle. Incubation period — 3J/2 to 4 days. The larvae emerged 

 by eating the shell at the top but in no case more than sufficient to 

 get out. 



Young larva. — Length, i mm. ; slug-shaped. Color, light brown. 

 Head, black. Feet, dark brown. There is a row of small tubercles 

 on each side of the dorsal line, one on each segment, which bears a 

 long hair, brown at the base but growing lighter at the tip, and point- 

 ing slightly backward on segments 2 to 11 inclusive, forward on the 

 first segment. A little below and posterior to this row, each of seg- 

 ments I to 9 bears another hair which, with the exception of those 

 on segments i and 2, bends abruptly backward and is shorter than 

 the first described hair. On segments i and 2 they are of about 

 equal length and point forward, especially on the first segment. The 

 lateral line, marked by minute hairs at the forward edge of each 

 segment is present on segments 2 to 10 inclusive. 



The substigmaial line is light brown, raised and has three dark 

 tubercles on each segment, the middle one being lower down in the 

 line than that on either side. Each bears one hair, the middle one 

 being the longest. 



The cervical shield is dotted with black. Prolegs light brown, 

 each bearing one small hair. The last segment has a number of 

 small hairs around the edge. Spiracles, dark brown. 



Each segment is slightly depressed vertically in the center and has 

 several minute dots ; one slightly below, and one on, the lateral line, 

 and two others, one above the other toward the dorsum. 



As the larva grows older, the color becomes light green, dorsal 

 line dark green, with a light line on either side. Substigmatal line, 

 light green. Head toward the end of this stage is hidden by the 

 first segment which is carried horizontally. 



Time between hatching and the first moult — 4 days. 



After Urst moult. — Length 3 mm. Feet and head black. Body 

 pale green. The first segment is carried horizontally and is covered 

 with small colorless hairs pointing forward. Segments 2 to 9 and 

 segment 11 bear each one long hair pointing backward, and set in 

 a small light green tubercle on each side of the dorsal line. There 

 are also numerous smaller hairs scattered over the dorsum. In the 

 middle of the loth segment there is a gland opening at right angles 

 to the dorsal line. It is the secretion of this gland that is attrac- 

 tive to the ants. The last segment is edged with short hairs. 



The raised substigmatal line is yellow-green and is fringed with 

 small colorless hairs, the three of the preceding stage being promi- 

 nent. Sutures, dark green.
