140 CATERPILLARS AND THEIR MOTHS 



grew into a fine red-spotted myops and became a pupa 

 before driqnferarum had molted for the fourth time. 

 But at first the two little crawlers were much alike. 

 They had round pale green heads, slender pale green 

 bodies with yellowish subdorsal lines, and lateral lines 

 on the thoracic segments. Their horns were slender, 

 of medinm length, pale red, and rough. 



Four days after hatching, (Irupiferarum molted. 

 The head was green, round, granulated with pale yel- 

 low. The body was green granulated with pale yel- 

 low, and had faint subdorsal, lateral, and oblique lines 

 of yellowish granules. The horn was red, the legs and 

 props were green, the anal plate was edged with 

 yellow. 



Eight days later it molted again. The head was less 

 round, was green, and had yellow granules and face- 

 lines. The body was apple-green, with bright yellow 

 subdorsal lines, yellow lateral lines on the thoracic 

 segments, yellow obliques, edge of anal plate, and 

 granules. The general effect was very yellow rather 

 than green. The legs were green with red tips, the 

 props were green, and the horn was bright carmine 

 and rough. 



In five days the third mol!: occurred. The head was 

 not quite round, and was apple-green with sharp yel- 

 low granules and faint yellow face-lines. The body 

 was apple-green with sharp granules of bright yellow, 

 and obliques of yellow granules with a very narrow, 

 faint line of mauve on their upper edge. The spiracles 

 were red but not conspicuous, the legs yellow with red 

 tips, the props green. The anal plate was edged with 

 bright yellow. The horn was red, long, and stout,
