OEEURA FURCULA. 139 



and coming down low, with a square stirrup-leather on 

 the side of 8 ; the colour of the saddle rich brown, 

 tinted with crimson; a very fine yellow dorsal line 

 with dark edges, and some yellow slanting lines on 6 — 

 9 ; sides rich yellow-green, belly more glaucous green, 

 some very small dark dots on the side, the spiracles 

 ringed with brown, the tails pale brownish, with two 

 yellow-green rings. 



The largest larva I described was over 30 mm. in 

 length, the tails 7 mm. long, the figure was of the 

 pattern of vinula, but more slender; the head small 

 with flat face, the front of 2 wide and squared, and 

 bearing still two rough, low projections ; on the hinder 

 part of segment 3 a transverse, dorsal hump, the body 

 from 10 diminishing to a point at 13, the tails slightly 

 rough. The dorsal mark begins wide on the front of 

 2, narrows to the hump on 3, still narrower on front 

 of 4, whence it widens through 5 and 6, and at 7 

 begins to descend the side rapidly, sometimes to the 

 spiracle level, but goes up again, at 8 descends in a 

 squarish patch enclosing the spiracle, and then ascends 

 again, at 9 begins at the level of the spiracle, but slopes 

 rapidly up to the back, very narrow at 12, thence 

 widening on 13, but afterwards growing narrow once 

 more. The colour of this saddle varies ; in one example 

 it was lilac, with some pale streaks in the centre, and 

 on 6 — 8 at its widest it contained on either side a 

 rich yellow patch turning to orange, with some lilac 

 slanting lines ; all along bordered with a fine bright 

 red line, and outside that again with a yellow line ; in 

 another larva the saddle was deepish purple with a 

 mealy freckling, the patch at the wide part fiery orange- 

 red, with purple slanting streaks ; the saddle bordered 

 with a line of dark purple, then vivid crimson, and 

 lastly bright yellow. The larvaB on approaching full 

 growth had the dorsal saddle much tinged with 

 greenish, and the yellow and crimson and purple marks 

 not so vivid. The head claret-brown in front, darkest 

 on the top, greenish at the sides, mouth purple, the
