The British Butterflies Described 



and locality make it vary a good deal in the time of its 

 appearance. It has been found from the North of 

 Scotland to the South of England. July is the month 

 to look for it. I always find it more abundant near 

 the coast. It is a bold flying species, and often difficult 

 to capture ; but in good settled weather I have taken 

 it frequently at rest on thistle-tops at sundown. 



THE HIGH BROWN FRITILLARY {Argynnis Adippe}, 

 Plate IV., Fig. 5. In this and the foregoing we have 

 again two species very easy to confound, and all the 

 more so when we note that stable characters are some- 

 what hard to find on the upper surface of the wings 

 in general the ground colour in Adippe is richer and 

 darker, and the outer margin of the fore-wing is not 

 so rounded as in Aglaia, being either straight or very 

 slightly concave. The arrangement of the second row 

 of spots, which runs round near the outer margin of both 

 wings, is different in the two species, but they are very 

 inconstant and even vary in the sexes ; so the under side 

 must be again consulted (Plate X., Fig. 2). And here 

 we have an unfailing test. In Adippe, on the under side 

 of the hind- wing near the outer margin, there is a row 

 of dark red spots lined internally with black, and in the 

 centre there is a small pearl spot. These eyelike spots 

 are never present in Aglaia. The general green tint, 

 too, of Aglaia is absent in Adippe. The silvery spots 

 on the under side of the fore-wing of Aglaia are rarely 

 to be seen in this species. In some females of Adippe 

 three shadowy spots are visible near the tip. I have 

 never seen these on a male ; so we have it that, in the
