The black marks are pulverulent and irregular in shape, differ- 

 ing in different larvae. Length 3 to 4.3 mm. 



Stage V. — Shape as before and in all no essential change. 

 Greenish yellow, depressed spaces (i) and (4) whitish, broadly 

 surrounded with black, the other spaces not, or but faintly in- 

 dicated, (i) paired except on joints 12-13, doubly paired on 

 3-4 and indistinctly so on 4-5. 'On the sides the spots are 

 rather irregular, but there are no conspicuously large ones as 

 before, (4) being surrounded by black on all the segments, 

 most so toward the extremities ; (6) also defined on some seg- 

 ments. Subdorsal horns of joints 3 to 5, 11 to 12 long, all the 

 rest short, 6 and 10 especially so, all fully spined. The large 

 horns have a purplish tint, due partly to the color of the spines, 

 the short ones are yellowish, clearer, less opaque and less 

 greenish than the body. Skin granular, the granules rather 

 sparse and finely shagreened between, conic, even spinulose 

 pointed, especially dorsally on the thorax, where each has 

 black pigment in the base, elsewhere clear. The smallest 

 horn is the subdorsal of joint 6, which has not over half a 

 dozen spines. Cervical shield large, black, the rim smooth, 

 with setae. The pigment is more yellowish and opaque in the 

 centers of the segments dorsally and laterally. The long horns* 

 are about as long as the diameter of the body, prominent. At 

 the end of the stage the dorsal space and the lateral one above 

 the lateral horns are filled in with bars of light green pigment 

 except in the .segmental incisures ; but dorsally on joints 3 and 

 4 the bars are narrower. Long horns faintly purplish. Length 

 of larva 4.3 to 6 mm. 



Stage VI. — Somewhat flattened ; dorsal space broad, flat, a 

 little concave at first, curving over at the ends. Lateral space 

 nearly perpendicular ; lateral ridge projecting ; subventral space 

 small, retracted. Subdorsal horns on joints 5 and 1 1 moderately 

 long, about half the height of the body, shorter than before both 

 relatively and absolutely. Those of joints 3, 4 and 12 shorter 

 than 5 and 1 1 . Laterals moderate, about as long as wide, sub- 

 equal. The .subdorsals of 6 and 10 are very small, as before, 6 

 the smallest, 7 to 9 a little longer, air inconspicuous. Horns 

 all densely spined. Horns, except the subdorsals of joints 6 

 to 10, faintly purplish. Color, two shades of green as in the
