shallowly pitted and covered with a short yellow down ; color greenish- 

 white, with dark brown spots and patches ; a large brown triangle over 

 mandibles, a small sub-triangular patch at top in the depression, a sub- 

 crescent patch along base of each vertex, and a stripe from vertex half 

 way down side, another down the back ; the ocelli black on brown 

 ground ; on each vertex a short, compressed, fleshy, white process, and 

 single white spurs along back of head at top and down sides ; on the 

 sides and tops of the processes and spurs many long white hairs. To 

 next moult 4 days. 



After 2nd Moult. — Length .26 inch ; similar shape, stouter, the sides 

 somewhat less rounded than dorsum, the base broadest ; the tails more 

 produced ; the tubercles as at next previous stage, white and yellow, but 

 broader and flattened ; the two rows of each dorsal band a little separated 

 so as to show a dull green imperfect line ; the side stripe much widened ; 

 segment 2 wholly yellow ; head shaped as before, the depression more 

 angular, green behind, green with dark brown patches at sides and front ; 

 these patches much extended, the one at top nearly meeting by a triangu- 

 lar projection the triangle from mandibles, and the one from base of 

 process in nearly all cases protracted to outer end of mandibles, so that 

 the white in front is confined to two curved vertical stripes forming with a 

 cross line between the two triangles the letter H, each upright, incurved ; 

 the processes stout, short, cylindrical, evenly forked at top, each fork 

 bluntly rounded, and a little tapering ; at the base is a spur turned for- 

 wards, and along the back and sides are single spurs ; color of process 

 black in front, green behind ; along back of head at top spurs in line, and 

 so dowai the sides, diminishing gradually in length, the upper ones bent 

 down ; all as well as the processes pilose. To next moult 3 days. 



After 3rd Moult. — Length .38 to .4 inch ; stouter, the back more 

 arched ; marked as before ; head almost precisely as before. To next 

 (last) moult 5 days. 



After 4th Moult. — Length .6 inch, greatest breadth .14 inch; same 

 shape as at close of last stage and banded in same way, viz., a narrow 

 dark green medio-dorsal stripe ; a broad upper lateral yellow-green stripe, 

 a lower lateral one of same color ; the tuberculated bands on dorsum 

 each divided by a medium yellow-green stripe, not so clear or uninter- 

 rupted as the others ; the inner row of each band is quite narrow and is 

 yellow, the outer row is wider and white ; below the upper lateral stripe
