Horn stout, moderate, slightly curved, coarsely granular; color blackish, 

 pitchy, thickly covered with little black dots in pale circles; seven oblique 

 lateral pale shades. Thoracic feet, horn and areas around the spiracles 

 black. Thoracic segments (joints 2-4) without dots, smoky-brown; cer- 

 vical shield area paler, bisected by a pale line into two halves, narrowly 

 lined with black. A black patch on joint 2 posteriorly, partly concealed 

 by the " collar." On joints 3 and 4 behind the collar is a large, elliptical, 

 sooty-black patch, surrounded by a white shade, which is more marked 

 anteriorly, and obtains also on the collar-like projection before the patch. 

 Anal plates moderate, triangular, granular, setiferous, concolorous.

Penultimate stage. Head smooth, evenly rounded, dark brownish 

 black, sutures broadly pale; mouth parts, except the jaws, also pale. A 

 few short, pale hairs above the mouth; width 4.3 mm. Body cylindrical; 

 anal feet large, with triangular corneous plates; abdominal feet long, with 

 two rows of elongated, setiferous tubercles. On the body are three seg- 

 mentary rows of modified processes. Row i on joints 2-13 subdorsal, a 

 single dorsal one on joints 12 and 13 with a subdorsal one each side on 

 the anal plate; row ii lateral on joints 2-13; iii, subventral on joints 2-13 

 'and a small row iv on joints 2-6, 11-13 below row iii. These processes 

 resemble antlers, being furnished with about six thorn-like curving 

 branches; row i on joints 2-4 and 12, about twice as long as the others, 

 thicker and with more branches. Row ii on joints 3 and 4, and i on joint 

 13 slightly longer than the others, but shorter than these just mentioned. 

 Apices of processes minutely setiferous or bare; edges of the 3 anal 

 plates with smooth conical, setiferous tubercles; color blackish, nearly 

 black; processes all shining black, except the basal half of i and ii on 

 joints 2-4 and the short i on anal plate which are white. In another ex- 

 ample the bases of many of the processes are white; spiracles large, 

 black. 



Last stage. Head as before, but the pale area around the mouth 

 spreads over the sides of the lobes; ocelli black; a few very short, but 

 bristly setae; width 6.2-6.5 mm - Processes and tubercles all proportion- 

 ately much shorter than before, the longest one scarcely more than half 

 as long as the corresponding ones in C. regalis, the branches reduced to 

 short, conical prominences, each with a very short spine at tip; tubercles 

 on feet and anal plates shortenened, rounded, with small setae; coloration 

 much as before, but the body is paler, appearing to have been blackish 

 olive. A whitish stigmatal shade, defined along the undulations of the 

 subventral ridge. Spiracles large, black. Thoracic feet and anal plates 

 partly pale.
