of scarcely perceptible raised polygonal cells, which average .04 mm. 

 in diameter. Color a very delicate pale green, glistening. Height 

 .72 mm. 



The young larvae, upon emerging from the eggs, at once 

 attacked the empty shells and in nearly every instance devoured 

 them to the bases. 



Lari'a. First Instar. Head suhtriangular, rounded, higher and 

 broader than any part of the body, and with the median suture only 

 faintly impressed. Head .56 mm. in diameter, black, shining, delicately 

 rugose and clothed with only a few short straight sharp but weak color- 

 less hairs, at scattered intervals, but most numerous about the frontal 

 triangle. These hairs .08 mm. in length. 



Body slender, quite uniform, tapering only slightly posteriorly. In 

 color the body is a pale lemon yellow, with a very delicate whitish sheen. 



Series of minute, bristle-bearing papillae arranged on the body as 

 follows : A subdorsal series, located on the anterior portion of the seg- 

 ment, one on each side to a row and rather sharply inclined outwards. 

 A laterodorsal row, centrally located. A suprastigmatal row, placed 

 slightly anterior to middle of segment. An infrastigmatal row, situated 

 just posterior to middle of segment. On the thoracic segments the sub- 

 dorsals become supralaterals and are there centrally located. These 

 papillae are black, .01 mm. in height, and of the same diameter at base. 

 The arising hairs are black, .04 mm. in height, very slightly enlarged an.l 

 flattened apically, where the diameter is .01 mm. ; the tips pellucid. 



Each segment with six, fine, transverse creases, of which the foremost 

 one is the most conspicuous. The transverse dorsal shield of first 

 thoracic segment shining black, narrow, extending laterally to just above 

 the spiracles, .03 mm. in width, but thickened subdorsally. A few fine 

 black hairs on the shield. Anal segment with four, subdorsal, pale 

 yellowish papillae from which project long, colorless, spiculiferous hairs 

 posteriorly, these being .40 mm. in length ; also a few shorter, colorless, 

 wavy hairs bordering the anal segment, some as long as .20 mm., others 

 but .08 mm. 



Pseudostigmatic blisters laterally on second and third thoracic seg- 

 ments geminate, pale testaceous. Spiracles round, .02 mm. in diameter, 

 with a prominent brownish orange ring. On the eighth abdominal seg- 

 ment the spiracles arc enlarged. .04 mm. in diameter, elevated, and 

 higher above the line than the others. A fine, even, dark green dorsal 

 line, .02 mm. in length. 



Prolegs and ventral surface pale greenish yellow. I>gs very pale 

 yellow brown, shining. 



Length 2.56 mm. Height at first thoracic segment .44 mm. Width at 

 anal segment .38 mm.
