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. Litersegmental 

 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 mm. in size 

 and is surrounded by a slight irregular web; color, dark brown. 



Food Plants.— ThG larvae were found each on a different plant, as 

 follows: Mangrove {Rhizophora mangle), Sea Grape {Coccoloba uvi- 

 fera'), Cocoanut Palm and Coccoloba floridana. All the four larvge 

 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.
