96 DECIDUOUS FRUIT INSECTS AND INSECTICIDES. 



DESCRIPTION OF STAGES. 

 THE ADULT. 



This leaf -roller was first characterized and named in 1863 by 

 Walker in the Catalogue of the British Museum, volume 28 . page 

 373, as Eetinia argyrospila. The original description is as follows: 



Female. Reddish, cinereous beneath. Head ocliraceous; palpi porrect, broad, 

 extending very little beyond the head; third joint extremely short. Abdomen 

 cinereous, extending a little beyond the hind wings. Forewings rectangular at the 

 tips, with several transverse slightly undulating black streaks: space along the 

 interior border and some incomplete irregular bands silvery cinereous; costa straight, 

 with three large silver}'- white marks, exterior border slightly oblique hindward. 

 Hind wings brownish cinereous. Length of the body 3| lines: of the wings 10 lines. 



a. Georgia. From Mr. Milne's collection. 



The moths measure from 17 to 23 mm. across the expanded wings. 

 The length of the body varies from 8 to 10 mm. There is a wide 

 variation in color. The general color of the forewings varies from a 

 light brown to a cinnamon or rusty brown. The markings on the 

 forewings also show a variation in size, pattern, and color. Ordinarily 

 each forewing has three whitish markings. The hind wings are 

 without markings and are of a uniform ashy-gray color. (PL XVI, 

 fig. 2, at left.) 



THE EGG. 



The eggs are deposited in sightly convex, oval masses or patches 

 which vary in color from a light gray to a dark brown. The egg 

 masses are covered by a hard protective coating. The size of the 

 masses is variable. The average for 20 was found to be 5.1 by 2.6 mm. 

 The average number of eggs per mass is about 90. The individual 

 egg is quite small and is a little more than twice as long as wide. 

 The eggs are packed in the mass very tightly. A longitudinal section 

 of an entire egg mass presents a honeycombed arrangement. (PI. 

 XII, fig. 1; PI. XVI, figs. 1, 3.) 



THE LARVA. 



When newly hatched the larva measures about 1.5 mm. hi length 

 and is pale yellowish green, with the head and thoracic shield dark 

 brown or nearly black. At this time the thoracic legs are nearly 

 black, while the prolegs are of the same general color as the body. 

 As the larva develops the color of the head, thoracic shield, and legs 

 gradually changes to a light brown and the body takes on a darker 

 shade of green. Before pupating the thoracic shield and legs of the 

 larva take on an olive-green tinge, slightly darker than the rest of 

 the body, which is now a light green. The larva is sparingly clothed 

 with short hairs, which arise from rather inconspicuous tubercles. 

 The full-grown larvae measure from 16 to 23 mm. in length and from 

 2 to 2.2 mm. hi greatest width. The average size for 10 larvae was 

 found to be 20.3 by 2.04 mm. (PI. XII, fig. 2.)
