Life-History of a Cochlidian Moth 17 



red, those of joints 4 and 5 red-tipped, the rest green. Dorsal 

 marking expanded in the intersegments 3-4, 4-5, 5-8, 8-10, and 

 very shghtly lo-ii and 11-12, the first and last green-filled, the rest 

 dark purple, cut by the yellow dorsal line and the pale depressed 

 spaces (i), broken at joint 8, broadly yellow-edged to the sub- 

 dorsal horns. Horns with stinging spines, no caltropes. Skin 

 sparsely clear granular. Length, 4.1-5.2 mm. 



Stage VII. — As before. The subdorsal horns of joint 13 

 are long and tapered. The subdorsals of joints 3-5 are red, those 

 of 12 and 13 sHghtly red-tipped; a greener fine within subdorsal 

 ridge. Length, 5.2-6.9 mm. 



Stage VIII. — Subdorsal horn of joint 3 a little longer than those 

 of joints 4 and 5, but all now very short, those of joints 6-11 still 

 shorter, of 12 a little longer, of 13 long and tail-Hke. Side horns 

 all very short. The level narrow dorsum is yellow and opaque, the 

 dorsal band of purple widens into five subequal patches, nearly 

 divided at joint 8, where the purple is replaced by red and is Unear 

 only. The last patch, on joints 11 and 12, is a Uttle smaller; joint 

 13 dorsally green. Horns bright red. Sides all clear green; a 

 broken white line along the lateral ridge and irregular white marks 

 in the lateral depressed spaces. Skin granular; spines pale; no 

 caltropes, except perhaps two or three on the basal anterior green 

 spot of the horn of joint 13. Dorsal impressed dots (i) greenish 

 with white rings. A dorsal white line narrowly cuts the purple. 

 Length, 6 . 9-9 . 3 mm. 



Stage IX. — Long, rather narrow, quadrate, a little tapering 

 behind. Dorsum broad, flat, not arched and scarcely higher at 

 joint 5, yet a little so. Subdorsal ridge indicated by change in 

 direction. Sides perpendicular or nearly so, the lateral space broad, 

 continuous with the subventral space which is infolded in the middle. 

 Subdorsal horns distinct, short, those of joints 3, 4, 5, and 12 mod- 

 erate, those of joint 13 long, nearly three times as long as the ones 

 on joint 12, the rest short, those of joints 8 and 11 a Httle larger 

 than the others. Side horns short, sessile, wider than long, those 

 of joints 3 and 4 a little longer than those of 6-12. Caltrope 

 patches on the horns of joints 6-12 and on the base of the subdorsal 

 horn of joint 13, large on joints 12 and 13, then progressively smaller
