THE STUD Y OF INSECTS. 
The Great Spangled Fritillary, Argynnis cybele (Ar-gyn'« 
tiis cyb'e-le).—This species (Fig. 471) will serve to illustrate 
the appearance of the larger members of this group, those 
belonging to the genus Argynnis. In this genus vein III 3 
of the fore wings arises before the apex of the discal cell. 
There are a number of common fritillaries which resem¬ 
ble the preceding in color and markings but which are much 
smaller, the wings expanding considerably less than two 
inches. These belong to the genus Brent his (Bren'this). In 
this genus vein III 2 of the fore wings arises beyond the apex 
of the discal cell. 
The Variegated Fritillary, Enptoieta clatidia (Eup-toi-e'ta 
clau'di-a).—This butterfly agrees with the smaller fritillaries 
(. Brenthis ) in the origin 
of vein III 3 of the fore 
wing beyond the apex 
of the discal cell, but 
differs from them in the 
shape of the fore wing, 
the apex of which is 
much more produced 
(Fig. 472), and the outer 
margin, except at the apex, concave; it is also considerably 
larger. 
This species occurs throughout the United States east of
