and antennae pale; eyes black. Width 1.7 mm. The horns on 

 joint 2 are three spurred, wine-red, punctured; markings much as 

 in the last stage. A yellow dorsal band forms a triangular patch 

 on joint 2, narrows almost to obsoleteness on joints 3 and 4, widens 

 again on joints 5-8 and ends triangularly. It begins again in the 

 middle of joint 9 and widens on joints 10 and 11, where it ends ab- 

 ruptly, excavated so as to appear furcate. It is very narrowly and 

 faintly continued on Joints 12 and 13, and is bordered on both sides 

 by a broad wine-red band, which contains fine yellow streaks, and 

 is continued twice downward to the feet, on joints 5 and 4 obliquely, 

 and on joints 7 and 10 straight. The rest of the body is pale green- 

 ish. Anal feet long, wine-red. Length 12 mm. As the stage 

 progresses, the markings approach those of the next stage. 



Fourth Stage. — Head shaped as before, dark red-brown, the 

 indented band in front pinkish; triangular plate white; antennae 

 yellow; a darker band on the head posteriorly, otherwise as before. 

 Width 2.1-2.6 mm. The body is nearly cylindrical, enlarged dor- 

 sally (arched) at joints "8 and 9, and tapering thence to joint 13. 

 Anal feet long, not used in walking; two three-spurred cervical 

 horns red-brown, punctured, and tipped with a hair, only about 

 1.5 mm. long. Body leaf green, the dorsal band yellow between 

 the horns, elsewhere white, distinct. It widens posteriorly to joint 

 7, narrows abruptly to a point on joint 8, begins again on joint 9, 

 widening to joint 11, where it divides into two parts, which meet at 

 the anal plate, enclosing an elongated oval patch of the ground 

 color. Anal feet white above, brown below; three lateral brown 

 spots mottled with yellow, the first oblique on joints 4 and ^, nar- 

 row; second on joint 7 and partly on joint 8, large, extending from 

 the dorsal band to the foot of joint 7, darker subventrally; the third 

 smaller, on joint 10 a little oblique and not reaching either the foot 

 or dorsal band; some minute black spots over the lateral region. 

 Spiracles on joint 2 reddish. Thoracic feet brown, abdominal with 

 a fine brown band. Length 22 mm. 



Fifth Stage. — Head shagreened, purplish brown, the apices 

 of the lobes black. In front is a broad, pink, vertical stripe a little 

 irregular in outline, very narrowly divided by the darker central suture 

 and becoming white behind the vertex. Triangular plate white, labrum 

 pinkish; maxillae black, antennae brown, their conical base yellow, 

 ocelli black. Width of head 3.3-3.8 mm. Cervical horns absent, 

 their places represented by a pair of minute tubercljes bearing each a 

 single hair. The body is smaller at joints 5 and 6, enlarged dorsally 

 at joints 8 and 9, and slopes again to joint 13. Anal feet rather
