or olive-brown and salmon, or green mottled and specked with brown over 

 dorsum (three distinct styles of coloring) (Figs./,/^,/^); the side blue-white; the 

 dorsal patch triangular, one angle being on 9, the others on sides of 7, color 

 salmon ; 11 to 13 salmon mottled green ; in the brown examples 2, 3, 4 are green 

 specked and mottled in shades from pale to olive-brown ; in all is a salmon line, 

 in part macular, along verge of dorsum, and along lower part of side is another, 

 less distinct; from 5 to 11, on the sides, are obscure oblique streaks of light 

 specks, turned down and forward ; front ridge of 2 yellow, slightly arched, at 

 either end a yellow conical tubercle ; on this segment are two minute sub-dorsal 

 smooth green knobs ; on 3 are two such knobs, mid-dorsal, and two of larger 

 size, sub-dorsal, with a black bar on anterior outer side of each, the four in line 

 {Figs. f*,f°) ; on 4 are six knobs in an arc, the dorsal pair small, the sub-dorsals 

 largest; tbe two outer of these knobs on either side have each a pale blue or a 

 purple round spot on the dorsal side, and the sub-dorsals have also each a black 

 bar on the outer side; on 5 are two small dorsal knobs near front and two large 

 sub-dorsals on middle of the segment ; on 6, 8, 9, 10 each is a pair of sub-doi'sal 

 blue or purple dots ; on 12 and 13 each a pair of sub-dorsal yellow conical 

 tubercles, that on 13 the largei', all these on the ends of narrow cross ridges ; 

 head shaped as before; color pale red-bi'own, lower part of face greenish (Figs./ 



At twenty-four hours after second moult : length .5 inch, the green and 

 salmon deeper colored, the lateral stripes more conspicuous, the lower one broad 

 from 2 to 5 inclusive, the rest macular ; on 4 the outer blue spot shows a brown 

 ring. 



At forty-eight hours : length .56 inch ; the green now bluish with a gray tint, 

 the salmon specks and small spots obliterated, the lateral stripes in part obsolete ; 

 the dorsal patch changed to pale green except at the angle on 9, and a stripe on 

 the side of 8 and 7 ; the patches on 4, wliich are a marked feature at next stage, 

 now begin to show faintly, and in a few hours become pretty distinct (as seen in 

 Fig. /■*). Duration of this stage three days. 



After third moult, at twelve hours: length .6 inch; color green specked with 

 lighter or blue-green, least on anterior segments ; the salmon patch has mostly 

 disappeared, but has left some traces, varying in individuals ; the lateral bands 

 more or less distinct on two or three segments, the sides bluish or blue-green, 

 varying ; 2 has the front ridge as before, the processes at ends reduced ; on 3 

 are sometimes two minute sub-dorsal green knobs, and two dorsals between them, 

 but tbe last are often wanting even while the others are present ; on 4 is an 

 elongated ochre-yellow patch on either side, divided into two sections, tbe upper
