62 LLOYD'S NATURAL HISTORY. 



about an inch across the wings, which are glistening pale 

 ferruginous, with a row of large black sub- marginal eyes in 

 black rings in the lower part of all the wings. The anal angle 

 of the hind-wings is slightly produced, but not tailed. The 

 larva is described by Mr. Trimen as very broad and thick, 

 slightly narrower and thinner posteriorly; head very small. 

 It is green, with a lake-red head and dorsal line, and feeds on 

 Cotyledon cuncatum. The pupa is robust, rounded, and rather 

 tapering behind ; it is rather darker green than the larva, with 

 a faint red line on the hinder half of the back of the abdomen ; 

 it is attached to the under side of a leaf, head downwards. 

 " Mrs. Barber gave me the name of the larva's food-plant ; 

 and it is interesting to observe in her drawing how clearly the 

 green red-edged colouring of the insect accords with that of 

 the Cotyledon " (Trimen). 



Dr. Scudder appears to have mistaken the type of this 

 species (a very unusual error in such a careful and painstaking 

 compilation as his " Historical Sketch of the Generic Names 

 Proposed for Butterflies "), and quotes only the three species 

 described by Felder, without any reference to the preceding 

 remarks, commencing : " Diversitatem M. [Myrincc] eryli, 

 Godt. et afrinium (sipyli, Feld, atoli, Fabr.)" &c. Felder 

 also refers to a preceding note relative to his Myrina thedoides, 

 which commences, " Species haec et ejus affines, M, eryhts, 

 Godt. et sipyluS) Feld., a Myrinis palporum articulo secundo 

 capite breviore, tertio longo aciculari arcuato antennisque 

 graciliter dentatis recedunt." I infer from this that Felder 

 regarded the following species as the type of his genus.
