SATYRINjE. 201 



base of all the wings is blue, and the outer part of the hind- 

 wings is blue-black. On the under side of the hind-wings is a 

 very large black eye, containing a white crescent, and sur- 

 rounded by broad rings of tawny and brown. A little above 

 this is a small kidney-shaped yellowish spot, surrounded with 

 brown, and on the middle of the costa is a similar but larger 

 one. The surface of the wings beneath is grey, mottled with 

 brown. 



As a representative of this genus we have figured the follow- 

 ing species : 



CALICO ILIONEUS. 

 (Plate XXVIIL, Fig. 2.) 



Papilio ilioneus, Cram., Pap. Exot, i., pi. 52 A. (1777). 

 Morpho ilioneuS) Godart, Pap. Exot, ix., p. 448, no. 25 (1823). 



This species is very similar to C. eurylochus^ but has two pale 

 sub-marginal lines on the fore-wings instead of one. The figure 

 will give a fair idea of the general appearance of the upper sur- 

 face of the most typical species of the genus. It has been 

 drawn of half the natural size. The species is common in 

 South America. 



The species of Eryphanis, Boisduval, resemble Caligo, but 

 are smaller, with shorter and more pointed and angular wings, 

 and especially with smaller eye-spots on the under surface. 



SUB-FAMILY IX. SATYRIN^). 



Egg. About as high as wide, rather small, hard, translucent, 

 smooth, faceted, sub-radiate, or (rarely) ridged. 



Larva. Generally green, with two small horns on the head, 

 and a forked tail ; smooth, or slightly hairy ; thickest in the 

 middle, and tapering at each end. It feeds on grasses. 



Pupa. Short ; cylindrical, not angulated,
