p. PANDORUS AND AGHEMON 105 



tal, as before, and head and first segment were of a 

 bright, clear yellow-green. The second and thkd seg- 

 ments were speckled with black, and the whole body 

 was bright green, with a dark dorsal line, very faint 

 yellow subdorsal lines, and five oblique, regular oval 

 patches — not lines — encircled with black and sur- 

 rounding the uunoticeable spiracles. These obliques 

 were the unmistakable characteristic of pandorus. The 

 legs and props were green, and the horn was long, 

 very slender, deep red with black setae all over, yellow 

 at base with a black spot in front, and curled forward 

 over the back. The third segment was more swollen 

 than before. 



Achemon had the head flat, small, clear green, and 

 held horizontal. The body was clear, bright green, 

 dotted with yellow, and had no black dots. The yel- 

 low subdorsals were clearer than those of imndorus. 

 There were six pairs of obliques of yellow edged above 

 with dark green, longer and narrower than those of 

 }')andorus, as well as one pair more in number. The 

 legs and props were green, the anal plate was edged 

 with yellow, and the horn was long, very slender, deep 

 red, and almost black at tip, its base being yellow in 

 front with a shining black dot, and red behind, the 

 color extending part-way down the anal shield. In- 

 stead of curling forward, like the horn of pandorus, 

 ac}iemon\s horn was held perpendicular or bent back- 

 ward until it made a line with the dorsum. The 

 third segment was more swollen. 



Both species now ate through the leaf at the margin, 

 beginning at the tip of a lobe, and working down. After 

 every molt they ate the cast skins, except the masks.
