A. Final instar larvae with A2 scolus longer, slender, straight 
(although directed posteriorly), and with median spines ascend- 
ing celerio, paraena 
Pupae vary only slightly, the more apparent differences being in 
the length, and degree of curvature of the head horns, and in the 
shape of the dorsal projections on T2 and A2. Head horn shape and 
size do not appear to correlate with the two larval types seen so far, 
and perhaps varies even within a species. 
celerio, Panama (Aiello, Coley) 
Larvae are dark, mostly black above and green laterally, with 
pinkish lateral spots on A2-4, 7 & 8; scoli on thorax and A7 & 8 
are pale, while that of A2 is black; subspiracular scoli A2-4 are 
mixed pale lime and bright green. A black subspiracular stripe 
passes along the thorax and turns sharply upward across A1 and 
fuses with the dark scolus of A2. A few days before pupation the 
pinkish lateral marks change to green, as do the scoli of T3 and 
A7 & 8; the scolus of A2 remains dark. Just prior to pupation 
larvae fade to a dirty yellow. Larvae rest in the curled position 
with the posterior end elevated and the white undersurface of A8 
& 9 exposed, and in this configuration resemble a bit of fallen 
moss and lichen mingled. 
Pupal head horns are long, and slightly curved near their tips. 
Adults resemble iphicla in wing pattern. 
nr. celerio, Panama (Aiello) 
A larva resembling celerio produced, but with the A2 scolus 
short and broad, a pupa that had short head horns and appeared 
identical to my nr. paraena. 
Unfortunately the pupa died and its identity remains a 
mystery. 
celerio diademata, Mexico (Comstock & Velazquez, 1960) 
The illustrations of this larva and its pupa indicate member- 
ship in GROUP I; the larva is clearly of the celerio type having 
long narrow scoli, even on A2. The pupa closely resembles that of 
the celerio reared by me in Panam&; the head horns are long and 
slightly curved just before their tips. 
The authors report that their larva faded to yellow just before 
pupation.
