densely covered with yellow scales; the patch of scales on costal margin above 
discal row of spots much enlarged ; the cell not dusted, but black. Secondaries 
have the nervures of the disk heavily edged with black; the outer edges of the

ginal spots; the interior portion of the black border covered with yellow scales 
above which are patches of blue; the ocellus as on upper side.

apple green, paler on sides and beneath, banded with black and spotted with

anterior edge of the band on second segment are four yellow dots, two on either 
side of the dorsum; on the third and fourth the same number, but filling exca¬

with each of these two bands, is a black, triangular spot; from fifth to twelfth

one placed on the posterior side of the band, either wholly or nearly inclosed 
in the clubbed extremity, the others, on the anterior side nearly occupying the 
width of the band, and often entirely; along the base, above the legs, is a row 
of round black spots from the fifth to eleventh segment, one spot on the mid¬ 
dle of each on fifth, sixth, and eleventh, but on seventh to tenth two, one 
being near either edge of the segment; the last, or thirteenth segment, has
