spinulose white hjiir.s. Segments short, contracted, the incisures dis- 

 tinct; no shields. Tubercles ia+ih+iia on joints 8 and 4, distinctly 

 united on a flattened, somewhat fan-shaped wart; iib small, remote, 

 posterior; iv large; vi dark. On the abdomen tubercle i small, 

 dark; iv stigmatal, posterior, rather small; v larger. Seta? single, 

 no subprimaries. Body a little flattened, the lateral tubercles, espe- 

 cially of joints 3 and 4, a little prominent. Translucent whitish, 

 tubercles ii and iii on joints 11, 12, and 13 anteriorly dark ocherous. 

 Hairs white; legs colorless; the anal feet divergent. On eating, the 

 larvae became green from the food, the ocherous tubercles faded to 

 a dull color, joint 2 became contracted, and joints Sand 4 hunched up. 



Stage II. — Head flat before, rather strongly bilobed, colorless, 

 mouth brown; width, 0.65 mm. Body a little flattened, joints 3 to 5 

 largest, joint 2 retracted and weak, joint 13 small. Warts moderate, 

 spherical, with rather dense, white, stiff, spinulose hairs, those of 

 joints 3 and 1 the longest, very few on joint 2, the shield obsolete; 

 prespiracular and subventral warts present, slender, produced. On 

 joints 3 and 1 one wart above the stigmatal wart, discrete, round, 

 produced. On the abdomen wart i small, ii large, iii small, iv about 

 the same size, v small, vi larger on the somewhat produced sub- 

 ventral fold. No anal plate, but warts on the flap. Feet rather 

 slender, pale, with colorless plates. Luteous whitish, the sides washed 

 with pale vinous; deeper vinous about the subdorsal tubercles of joints 

 3 and 1 and below ii and iii of joints 6, 6, and 10; on 11 to 13 this 

 color is more distinct, forming streaks running downward and for- 

 ward from wart ii, on joints 12 and 13 changing from vinous to dull 

 orange red. Skin smooth, not shining. 



Stage III. — Head squarish bilobed, cl3"peus rather high, faintly 

 luteous, a vinous spot within at apex of paraclypeal pieces; ocelli black, 

 jaws only faintly brown; width, 0.9 mm. Warts rounded, produced, 

 colorless, except the subdorsal ones of joints 3 and 1. which are 

 vinous tinged, and ii of 12 and 13, which are orange. Wart i small, 

 ii and iii large, iv and v small, vi large, produced. Color as before, 

 ])ut the vinous shading covers the dorsum on joints 3 to 10. 



Stage IV. — Head rounded, slightly bilobed, clypeus reaching half 

 way to vertex; pale testaceous, jaws black at tip; ocelli black, Ave in 

 a semicircle and one below behind the antenna. Body short and thick, 

 pale testaceous, vinous tinged, especiall}" in dark, oblique streaks over 

 warts ii and iii on joints 11 to 13. Warts rounded, elevated, color- 

 less. Hair dense, stiff, flesh colored with black tips, barbuled. A 

 diffuse black dorsal patch on joint 5, the hair from tubercle i and part 

 of ii short and black. A slight similar shade on joint 10. Later 

 rusty l)rown, the green food showing only dorsall}^ on joints 10 to 12.
