^^rgr.— Sliglitly more than hemispherical, the base flattened, smooth, 
snblustrons l)lack, under a lens appearing minutely punctured. Diameter 
1 mm. Under a half-inch objective it is seen to be covered with flat, 
irregularly hexagonal and elongated reticulations which become very 
small at the micropyle. Between them the surface seems smooth with a 
few extremely minute punctures. 
First larval stage. — Head round, slightly shining, dark red-brown, 
almost black; clypeus and mouth parts paler, ocelli black; a few short 
hairs; width 0.5 mm. Body smooth, of even width; a pair of spinose 
subdorsal processes on joint 2; the anal feet modified into spinose stem- 
apods, 3 mm. long; cervical shield small, very dark. Color of body 
blackish red-brown, feet and venter whitish; two greenish dorsal patches, 
one on joints 3-5, the other on joints 8-10, elliptical, diflfuse at their ends; 
a third patch appears later, on joint 12. On the body are a number of 
minute setae. Tails twice annulated with yellowish and tipped with 
white. Extensile threads black, whitish at the base. 
The larvae eat only the parenchyma of the leaf during this stage. 
.Second stage. — Head rounded, slightly narrowing to the vertex, its 
sutures deep; color, even red-brown, with a few minute yellow dots; 
width 0.8 mm. Joint 2 is swollen, its subdorsal processes conical, thick, 
spinose; low, rounded, small, setiferons tubercles on the body, appar- 
ently normal in arrangement; anal plate and stemapods spinose. Body 
rusty brown with two elliptical, diffuse, dorsal patches of yellowish 
green, the anterior one on joints 2-6, the posterior on joints 8-10; sub- 
ventral region and all the feet pale whitish. Tails red-broAvn at basal 
half, then blackish, with two sordid white annulations. Length 3.8 mm. 
As the stage advances the anterior patch becomes larger, joins the sub- 
ventral colorf.tion, and is obscurely divided by a brown dorsal line, while 
the whole dorsal region, except joint 11, becomes pale. 
Tlunl stage. — Head higher than wide, roundly rectangular, flattened 
in front; reddish brown, the upper two thirds thickly covered with little 
round yellowish spots, but leaving a narrow line of the ground color on 
each side of the central suture above the clypeus ; antennae white ; width 
1.15 mm. Body enlarged at joint 2, bearing a pair of heavily spined sub- 
dorsal processes; tails minutely spined. The normal piliferous dots on
