tachable spines above the subdorsal horn of joint 13 and the 

 lateral of 12. The subdorsal horns of joint 6 are obsolete, 

 represented by only one seta ; those of 7 to 9 still distinct, that 

 of 10 small, about as 6 was in the stage before. The yellow 

 green blanket patch reaches the middle of joint 5 exactly ; it 

 then runs forward on the sides, three-fourths encircling the 

 subdorsal horn of 5, nearly half encircling that of 4, just 

 touching the base of that of 3 ; its lower edge passes backward 

 nearly straightly, just covering depressed spaces (6) to above 

 the lateral horn of joint 12 ; then it proceeds slightly upward 

 over the subdorsal horn of 12 and dorsally includes the single 

 depressed space (i) of joints 12-13. It completely surrounds 

 the subdorsal horn of joint 1 1, but does not appear to do so to 

 the rudimentary subdorsals of 6 to 10, as they are concolorous 

 or transparent. The yellow border about the subdorsal of 1 1 

 joins that about the edge of the blanket posteriorly. A white 

 line along the subventral edge. General shape as in the mature 

 larva ; horns short, conic, the longest about as long as wide at 

 the base ; spines salmon-colored with black tips. Dorsum of 

 joints 3 to 5 purple, shading to green on the edges ; subventral 

 area clear blue green ; blanket opaque light yellow green, shad- 

 ing to yellow about the edges. Glandular dots (i), (4) and 

 (6) ringed with rows of black spinules. Caltrope patches 

 large, on the laterals 4 to 12 and subdorsal of 13 ; detach- 

 able spines brown. Skin .spinules black on the dorsum of 3 to 

 5 and about edge of blanket ; el.sewhere colorless. A few cal- 

 tropes on the ends of the long horns. I^ength 11 to 13 mm. 



Stage IX. — No es.sential change. The detachable spine patches 

 are still narrow and transverse. Head 2.0 mm. wide; caltropes in 

 distinct patches on same horns as before. Length 1 3 to 17.5 mm. 



Stage X. — The bars of detachable spines are a little larger, 

 the subdorsal horns of joints 6 to 10 smaller, nearly rudimen- 

 tary, some with none, others with i to 8 spines. Head 2.4 

 mm. wide. Some caltropes also on the lateral horn of joint 3 

 as on 4 to 13 and on subdorsal of 13, the patches becoming 

 larger posteriorly, the largest on joint 13. All the horns are 

 short, none higher than wide. Length 17 to 24 mm. 



Stage XI. — Essentially as before. Detachable spines in large 

 thick bands. Shape as described. Coloration as in the last
