224 '^BE BUTTERFLIES OF THE 



the top in the depression, a subcrescent patch along the 

 base of each vertex, a stripe from the vertex half-way 

 down the side, and another down the back ; the oceUi 

 black on a brown ground ; on each vertex a short, com- 

 pressed, fleshy, white process, and single white spurs 

 along the back of the head at the top and down the 

 sides ; on the sides and top of the processes and spurs 

 many long white hairs. 



After four days the larva moults again, when it is 

 .26 of an inch long ; the shape similar but stouter, the 

 sides somewhat less rounded than the dorsum, the base 

 broadest, and the tails more produced. The tubercles 

 remain as during the preceding stage, but broader and 

 flattened, the two rows of each dorsal band a little sep- 

 arated, so as to show a dull green imperfect line ; the side- 

 stripe much widened, joint 2 wholly yellow. The head 

 is shaped as before, the depression more angular, green 

 behind, green with dark brown patches at the sides and 

 front ; these patches much extended, the one at the top 

 nearly meeting by a triangular projection the triangle 

 from the 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. The processes are stout, short, cylindrical, 

 evenly forked at the top, each fork bluntly rounded, and 

 a little tapering ; at the base is a spur turned forward, 

 and along the back and sides are single spurs ; color of 

 process black in front, green behind. Along the back of 

 the head at the top are spurs in line, and so down the 

 sides, diminishing gradually in length, the upper ones 

 bent down ; all, as well as the processes, pilose.
