Mr. Edward Doubleday's Remarks on the Genus Argynnis. 483 



In these the first subcostal nervule has its origin a short distance before the 

 very short upper disco-cellular ; the second arises opposite or immediately 

 before this nervure ; the third is less distant from the apex than from the 

 disco-cellular ; and the fourth is thrown off very soon after the third. The 

 lower disco-cellular is long, little curved, uniting with the median before its 

 second nervule. The cell of the posterior wings is open, the median and sub- 

 costal nervures are but little curved. Terinos Clarissa of Boisduval really 

 belongs to this group, notwithstanding its different colouring : Terinos may 

 therefore be used as a subgeneric name for it. 



Argynnis lole will form the type of a third section, the first subcostal ner- 

 vule arising a little before the point of contact between the upper discoidal and 

 the subcostal nervures, for here there can scarcely be said to be an upper 

 disco-cellular, the second about double the distance beyond the point of junc- 

 tion. The median nervure of the posterior wings is more curved than in the 

 preceding section, but in other respects the structure of both wings is nearly 

 similar. 



A fourth section is the genus Phalanta of Dr. Horsfield, in which, not- 

 withstanding their more rounded wings, Arg. Erymanthis and Prosope must 

 be included. Here the subcostal nervules are thrown off at nearly equal in- 

 tervals, the first being immediately opposite the short upper disco-cellular. A 

 slightly curved disco-cellular, of moderate length, connects the second disco- 

 cellular with the median immediately opposite its second nervule. The sub- 

 costal and median nervules of the posterior wings are much curved, the dis- 

 coidal cell being generally open ; but in Arg. Claudia and a species from Congo 

 closely allied to Arg. Phalanta it is closed by a very delicate disco-cellular. 



Several species in the preceding sections show a tendency to an angular 

 projection at the termination of the third median nervule of the lower wings ; 

 in Arg. Egesta, the type of the fifth section, they are absolutely tailed. In 

 this species the first subcostal nervule precedes the short upper disco-cellular; 

 the second is at rather more than an equal distance beyond it ; the third at 

 about two-thirds the distance between the base and the apex ; the fourth 

 shortly beyond it. The lower disco-cellular is straight, and joins the median 

 nervure opposite to its second nervule. The posterior wings have the cellule 

 closed, the subcostal and median nervures little curved.
