two twin minute black spinules situated close together. Body 

 pale reddish, color of an oak twing, variegated with yellowish ; a 

 distinct linear dorsal line and a broad diffuse line on thoracic 

 segments; an irregular series of large dorsal yellowish spots, those 

 on abdominal segments i — 4, and 6, 7 and 9 being the largest- 

 Anal legs moderately long, reddish. 



Stage III. — It molted Aug. i. Length, 8 — 9 mm. The head 

 is now large, wider than the body, subtrapezoidal in front, rounded 

 above, and slightly bilobed ; pale in front, yellowish on the sides. 

 An irregular pale reddish brown band on the vertex and on the 

 sides enclosing in front four irregular reddish spots of the color 

 of a dead leaf which may be called sere brown. Prothoracic spines 

 now stout and pale reddish, ending in three black spinules. From 

 each spine proceeds, a broad reddish brown band the color of a 

 dead leaf, and enclosing a large oval yellowish spot which extends 

 along the back of abdominal segments i to 4. This spot encloses 

 two reddish lines which dilate four times enclosing a roundish 

 white spot in each dilatation. On segments 5 — 7 is a long trian- 

 gular whitish spot enclosing two short reddish lines which dilate 

 twice, enclosing two narrow oval spaces. The back of segments 

 8 and 9 is reddish, the sides yellowish green, whitish; anal legs held 

 up at rest ; greenish with a red stripe within. The reddish portion 

 of the body consists of irregular fine reddish and greenish-yellow 

 lines, the former predominating. 



Stage IV. — It molted Aug. 8, A.M., and ate up the cast skin 

 before beginning to eat the oak leaves. Length, 12 mm. (Two 

 days before this molt the lateral sere brown spots appeared as in 

 this stage, but fainter.) By Aug. 12th it had become 20 mm. in 

 length. The three prongs of the prothoracic spines as in stage III, 

 reddish. Head a little broader and rounder than before, but with 

 the same style of markings. The markings of the body as in stage 

 III, but the greenish portion of the sides speckled with black. 

 Dorsal spots as before ; an irregular lateral sere brown spot just 

 above the base of the 3rd thoracic legs, and still higher up on ist 

 abdominal segment is a contiguous spot, making an oblique band 

 as in the other species. The reddish brown edging of the diamond 

 shaped dorsal spot on abdominal segments r to 4 extends down to 

 the base of the ist pair of the abdominal legs. In this stage there 

 is present a straw yellow infraspiracular line, just touching the 

 spiracles, and best marked on the abdominal segments, and above
