DESCRIPTIONS. 



The egg. Ivory-white, elongate oval, bluntly rounded on both ends, 

 one of which is only slightly the larger, with about 16 longitudinal ribs 

 merging at each end into an irregularly tuberculate polar area, these 

 ribs and the intervals between them crossed by other less prominent 

 ridges of which there are about 18 in the length of the egg. Measure- 

 ments (10 eggs measured):

Width 



The larva. Instar I. (Newly hatched). Length 1.15 mm. Head 

 width .1589 mm. Head deep fuscous to black, cervical plate fuscous, 

 body pale orange, the color heightened by the red color of the particle 

 of ingested egg-shell, paler caudad. Head and body with numerous pale 

 slender hairs, those on body arising from small dusky pinacula. 



II. Length 1.40, head width .2294 mm. Head black, cervical plate 

 deep fuscous, body reddish brown with a greenish tinge. 



III. Length 2.80, head width .3353 mm. Head dark yellow, semi- 

 transparent, unmarked, shining, ocellar area black; cervical plate 

 fuscous, shining, darker than the head; body pale green prominently 

 marked with transverse segmental bands of reddish brown overcolor 

 giving the entire insect a dingy brownish color. 



IV. Length 3.5, head width .4235 mm. No marked change. 



V. Length 5.9, head width .5118 mm. Head clear dingy yellow, 

 unmarked, ocellar area and narrow lateral margin black; cervical plate 

 transparent, dusky greenish-brown with two or three dusky spots 

 laterally; body reddish brown, pinacula fairly distinct especially on the 

 thorax, somewhat darker than skin and rugose but not sharply defined, 

 moderate in size. Setce pale and shining. 



VI. Length 7.0, head width .7415 mm. Head clear amber-yellow, 

 mouth parts brown, ocellar area and marginal line black; cervical plate 

 glassy, transparent and colorless except for the greenish color from 

 food, a dusky spot toward either end; pinacula prominent, rugulose 

 and chocolate-brown, rather large; skin finely granular, glistening, 

 covered especially caudad with reddish-brown or maroon overcolor 

 through which are small groups of small clear vacuoles along the lateral 

 margin. At a glance the larva appears dark reddish-brown with a clear 

 yellow head. 



VII. Length 10.0, head width .9794 mm. Head clear yellow with a 

 row of small dusky points across the face, ocellar area marginal spot 

 and line and mouth parts black; cervical plate transparent, greenish- 

 yellow; body heavily covered with reddish-brown overcolor in which 

 are rows of .small clear vacuoles along the dorsolateral margin ; skin dull,
