2. HHOVlIsETES Dyar 



(Sonyra, in part) 



Body relatively smaller; palpi much longer and smooth; hind tibiae with end 

 spurs only Venation as in female Phobetron. Caterpillar very Huffy, with all 

 the subdorsal spines long. 



1. I. beutenmulleri H. Edwards. (Similar to female pithecium; markings less 

 clean-rut, postmedial line not distinctly wavy; outer margin pale yellow; blue 

 scales more prominent. 20 mm. (H. 47:17.) 



The larva is green. 



Staten Island, New York, to Florida. 



Tribe Eucleini 

 (Tropic spined type) 



Larvae spiny, with subventral space reduced; tubercles tending to be 

 horn-like, not deciduous, poisonous in several species; 2 tubercles on 

 thoracic segments; first abdominal segment as before; first stage with 

 several hairs to a tubercle. Antennas of male moth normally pectinate 

 with simple tip ; hind tibia? usually with end spurs only, palpi mod- 

 erate, R 5 stalked, R 2 usually free. Pupa with lateral processes of 

 maxillas reaching to base of antennas. 



3. CNIDOCAMPA Dyar 



(Miresa) 



Palpi stout, very long, with second and third joints equal; male antennae 

 simple, laminate. Larva similar to Sibine but with rudimentary subdorsal spines 

 on the middle segments, besides the long ones, and with a small, blue rectangle 

 in place of the saddle-marking; feeding on Japanese Ivy (Ampelopsis). 



1. C. flavescens Walker. Fore wing with outer half light fawn, with two

Similar to Euclea, except for the sinuous inner margin. R 5 sometimes free but 

 closely connate with R 3+4 . Larva with strong anterior and posterior subdorsal 

 spines, but in middle segments rudimentary ones only, or, in our species, none. 



There are several other species in tropical South America.
