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



In M. Blanchard's genus Clothilda the subcostal nervules are at nearly equal 

 distances, the second being immediately opposite the scarcely visible upper 

 disco-cellular. The third median nervule is bent nearly at a right angle at 

 its junction with the lower disco-cellular, which is directed obliquely towards 

 the outer margin. The discoidal cell of the posterior wings is closed ; the 

 subcostal, like the median nervule of the upper wings, is bent nearly at a right 

 angle, where it is united to the disco-cellular ; the latter is united to the me- 

 dian nervure opposite to its second nervule. 



The seventh section includes Dr. Boisduval's section Majores of his genus 

 Argynnis, with the addition of Lathonia and some other species, as Niphe 

 and Childrence of the old world, Aphrodite, Cybele and Diana of the new. 

 Here the first and second subcostal nervules have their origin before the 

 very short disco-cellular ; the third rather more than half-way between this 

 and the apex ; the fourth at about an equal distance from the third and from 

 the apex. The lower disco-cellular is long, nearly straight, united to the 

 median beyond its second nervule. The cell of the posterior wing is closed 

 by a slender disco-cellular joining the median, which is there considerably 

 curved, exactly opposite its second nervule. 



The eighth section comprises the*Mmore* of Dr. Boisduval, with the ex- 

 ception of one or two species, and also includes several species from the tem- 

 perate regions of both North and South America. Our British species have 

 been generally placed in the genus Melitcea by English entomologists, but the 

 larvae and pupae, independent of other characters, point out their distinction 

 from it. These species differ from those of the preceding section in having 

 the first discoidal nervule united to the subcostal without the intervention of 

 any disco-cellular, in having only one subcostal nervule before this point of 

 junction, and in having the lower disco-cellular much longer. The disco-cel- 

 lular of the posterior wings is much stronger, and joins the median beyond its 

 second nervule. 



The remaining species compose the genus Melitcea, properly so called. They 

 differ from those of the preceding section in having a short upper disco-cellular 

 to the anterior wings, and in having the cell of the posterior wings open, a cha- 

 racter which, as was first pointed out by Herrich-Schseffer, serves to separate 

 them from the other European forms of the genus Argynnis of Godart, There
