feet, and tubercles shining black. A faint vinous shading dorsally on 

 joints 4, 5, 6, and 12, and distinct subventral sordid vinous blotches 

 the whole length. Tubercles normal, ib and iii, especially iii, larger, 

 ia and ib separate, iv behind the spiracle; no subprimaries. Tuber- 

 cles distinct, polished, black, the seta3 pale and obscure. Joint 12 

 slightl}" enlarged, tubercles i and ii of joint 13 anteriorly in a square; 

 joint 11 rather weak. The larva ate patches halfway through the 

 leaf on the upper surface and rested beside them. 



/Stage 11. — Head erect, high, narrowing above, a low vertical notch, 

 flattish before; pale luteous, the vertices of lobes narrowl}^ tipped in 

 smoky brown, ocelli dark; width 1.2 mm. Body cylindrical, joint 12 

 slightly enlarged, anal feet weak, approximate, but used. Whitish 

 green, smooth, a white subdorsal line; subventer and feet broadly 

 dark vinous, the anal ones only narrowly lined with this color; 

 thoracic feet black. Tubercles large, a little elevated, but whitish, 

 almost concolorous with the body, inconspicuous. Segments irregu- 

 larlj^ annulate; no shields. 



Stage III. — Head pale greenish luteous, punctate dotted in darker, 

 the sutures of mouth brown, sutures of clypeus and a central line also 

 dark; ocelli blackish; width 1.6 mm. Body cylindrical, normal, joint 

 12 with a small, sharp, dorsal hump. Green, yellowish shaded on the 

 thorax and along stigmatal line, subventer blotched with vinous, run- 

 ning down on the outer sides of the feet. Anal feet small, vinous 

 lined, used. Spiracles small, black ringed. Segments subannulate, 

 slightly shining, joint 6 with a very slight annular swelling. 



Stage IV. — Head high, flattened before and at the sides, vertex 

 slightl}^ notched; pale green, blotched with dull red on the sides below 

 and about the mouth, shading upward; width 2.5 mm. Body cylin- 

 drical, joint 6 with a central, slight, collared elevation, 12 with a 

 broad, low hump. Green, the space between the spiracles and the 

 feet broadly shaded in purple brown, slightly shading upward toward 

 the dorsum, more distinctly on the hump and quite darkly on the 

 annular elevation of joint 6. Thoracic feet and abdominal ones out- 

 wardly dark purple brown; spiracles black ringed. Tubercles slightly 

 elevated, green; anal feet small, used. Venter broadly pale green. 

 The transverse purple lines of joints 6 and 12 become more distinct 

 with growth. Later the dull vinous color shades nearly up to the 

 dorsal line, the purple dorsal ridges of joints 6 and 12 are slightly 

 relieved by whitish. 



Stage V. — Head higher and wider than joint 2, rounded, flattened 

 on the front and sides, narrowed a little above and slightly bilobed; 

 shining, smooth, yellowish green from the clypeus to vertex centrally, 

 the clypeus and sides shade in dark brownish red: mouth dark red; 

 surface shagreened slightl}^, making the red shade mottled-reticulate 

 in greenish; width, 3.5 mm. Body cylindrical, joints 6 and 12 with
