granules, becoming short clear spines on the ridges, but in small number 

 (Pi. VI, fig. 3). Impressed spots not large, well-defined and smooth, not 

 very deep ; the dorsal as before ; lateral ones all present, of the two 

 rows above the lateral ridge (Nos. 5 and 6), the segmental are a little 

 higher up than the intersegmental, both small. The two subventral 

 rows small, rounded, the lower a little anterior to the upper, not at all 

 confluent. The color is a leaf green, like the under side of a hickory 

 leaf, neither very yellowish nor whitish. The tubercles seem smaller 

 than in the previous stage, the setae more slender and less conspicuous. 

 Toward the end of the stage the yellow lines become very distinct, the 

 subdorsal bordered above narrowly, and mainly in the hollows of the 

 undulations with dark clear green. Impressed spaces all yellowish. 

 Length 4.2 to 7 mm. 



Stage VI. — Head green, eyes black, jaws brown; width 1.4 mm. 

 (calculated 1.44 mm.). Smooth, rounded, no tubercles on the ridges 

 (PI. VI, fig. 4 for front view), lateral outline low arched, highest a 

 little before the middle. Sets black, pointed, two on subdorsal ridge, 

 one on lateral ridge. Color soft green, much as before, a yellow line 

 anteriorly on joint 3, broad and distinct, joining a white line along the 

 subventral edge. A yellow line along the subdorsal ridge, from the 

 middle of joint 3 to the end of the broad tail, incised by the addorsal 

 depressions, the scallops filled in with dark green. All of the dorsal, 

 and two of the lateral (4 and 5) impressed spots pale yellow. A row 

 of intersegmental yellow spots below skin along lateral ridge. Skin 

 closely covered with conical granules, many quite sharp pointed. 

 Dorsal depressed spaces small, smooth, moderately deep ; lateral ones 

 obscure, hardly defined. Length 6.5 to 10 mm. Differs from Stage 

 V in having the ridges smooth, except for the short setae, rounded 

 angular, not elevated. 



Stage VII. — fPl.^VI, fig. 5, front view; fig. 10, side view; fig. 

 II, back view, allXa ; figs. 14, 15, natural size.) Width of the head 

 2 mm. Very smooth, setae fine, slender and short, entirely incon- 

 spicuous, not long and distinct as before. The setae representing 

 tubercles iv-rv along the subventral edge are distinct in comparison 

 with the greatly reduced ones on the suborsal and lateral ridges. Body 

 quite smooth, no ridges ; dorsal space flat, moderately broad ; lateral 

 space sloping, not concave ; subventral space small, retracted. Lateral 

 ridge slightly waved. Subdorsal line broad and distinct, yellow with 

 dark bordering spots above, the two lines joining on the quadrate tail. 

 Yellow line on joint 3 anteriorly as before. Impressed spots yellowish, 

 body light green. Skin closely covered with large, clear granules.
