102 SMERINTHUS OCELLATUS. 



the horn on segment 12 when perfect curved at the tip, 

 which is very sharp ; each segment has eight subdivi- 

 sions set with rough points ; on the back there is an 

 arrangement of these points marking out a dorsal 

 space, but there is no line ; the ground colour pale 

 glaucous green, the rough points opaque white ; on 

 segments 2 — 4 a white subdorsal line, on side of seg- 

 ments 5 — 12 seven oblique white stripes sloping 

 upwards ; each stripe has its lower half on one segment 

 and its upper half on the segment behind it, reaching 

 almost to the plain dorsal space ; each white stripe is 

 edged in front with deeper green than the ground. The 

 last of the seven is longer than the rest, and begins 

 below the spiracle on segment 10, runs through 11 up 

 to the subdorsal level, and then through 12 up into the 

 horn ; the horn is light blue, greener near the tip, and 

 is set with white points ; the spiracles yellowish-white, 

 strongly ringed with pinkish-brown ; the belly fuller 

 green than the back, and with smaller white points ; 

 the back of the head blue, the face granulated, full 

 green with a few white points, the lobes outlined with 

 yellow, the mouth reddish-brown, the thoracic legs 

 pinkish-brown, with white points on them ; the ventral 

 and anal prolegs green, with their feet slightly tinged 

 with pink. 



The larvae went underground for pupation, making a 

 cavity for themselves two inches down in the loose soil, 

 but I could find little or no silk spinning. The pupa 

 I have measured is all but 40 mm. long, and nearly 15 

 mm. at its widest, in figure very stout and cylindrical, 

 the head piece rounded, scarcely projecting, the wing-, 

 leg-, and antenna-cases very faintly developed and all 

 soldered together, the abdomen swelling in a regular 

 long curve, the last two segments tapering rapidly in 

 a round curve to the blunt end, which has at its dorsal 

 side a short, stout, conical spike set with rough pro- 

 jecting points, and ending in a small, strong, two- 

 pointed spine ; the skin granulated, smoother in the 

 three wide abdominal segmental divisions ; the general
