brown, on the upper side of the lateral horns of joints 6 to 12 and on 
the sides of the subdorsal horn of joint 13. Larva pale yellowish green, 
a yellow subdorsal band below the skin on joints 3 to 13, edged below 
by a dark green line, narrow, rarely partly replaced by red (Plate V, 
Fig. 3); a deeply waved green line above the subdorsal and lateral ridges, 
both edged with yellowish. Dorsal yellow line faint. Intersegmental 
glandular dots whitish. The subdorsal dark line is faint at the extremi¬ 
ties, but gives no longer any appearance of a central patch. Skin 
sparsely watery granular. Width of head, about 2.5 mm.; length of 
larva, 14.5 to 20 mm. 
Cocoon and pupa as usual. The cocoon is 11x6.5 nun. * n size 
and is surrounded by a slight irregular web; color, dark brown. 
Food Plants .—The larvae were found each on a different plant, as 
follows: Mangrove (Rhizophora mangle ), Sea Grape (Co c colob a uvi- 
ferd), Cocoanut Palm and Coccoloba flondana. All the four larvae 
produced moths; the last two mated in the box, and I obtained from 
them eggs and finally 95 little larvae. These ate whatever was offered 
them, as is usual in the Eucleidae.
