other specimens in which the spaces between the black lines and bars 

 in the middle of the fore-wings are filled in with yellow. In Pem- 

 brokeshire, where it is not scarce, specimens having the ground-colour 

 entirely fulvous are uncommon, while those having the interspaces 

 yellow are numerous. The lines and bands are also blacker, and more, 

 or even all, of the interspaces are yellow, or the broad band near the 

 margin of the hind-wings is of a clearer, brighter red, and outside 

 this a row of yellow, or sometimes white, spots. Sometimes a band 

 across the middle of the fore-wings is strongly suffused with black, 

 at others the third row of black markings, counting from the hind 

 margin, is absent, leaving a broad yellowish band, and occasionally in 

 such specimens the markings of the under-side of the hind-wings are 

 partially obliterated. These aberrations are found inland, and seem 

 to be permanent. 



Lasiommata JEgeria, L. — In South Wales the males of this species 

 are darker, and apparently more velvety in appearance than those 

 found further east, and the females have their spots larger and more 

 yellow. 



Lasiommata Megcera, L. — Abundant everywhere, and astonishingly 

 constant, but one aberration occurred in a wood in the middle of 

 Pembrokeshire ; a female having the central band filled up with 

 brown. 



Satyrus Tithonus, L. — Also an abundant and usually constant 

 species, but in some lanes close to the sea in Pembrokeshire specimens 

 commonly occurred in which the dots or spots of the under-side of 

 the hind-wings were more or less repeated on the upper-side. These 

 spots varied in different specimens in number, from one to four, and 

 sometimes they were white-pupilled ; more rarely specimens were 

 found with additional black dots on the upper-side of the fore-wings 

 — either one or two in a line below the large bi-pupilled black spot. 

 These spots occurred in both sexes, but did not always correspond on 

 both sides of the specimen. All these supplementary spots are small 

 and inconspicuous. 



Satyrus Hyperanthus, L. — In Pembrokeshire, where it is abundant, 

 this species exhibits the tendcncj 7 so often seen in Janira,to decolora- 

 tion of one wing, or part of a wing. One specimen, however, occurred 

 in which the entire upper-side was of an olive-grey colour. 



Camonymplia Pamphilus, L. — In the lowland districts this abund- 

 ant species is almost unicolorous on the upper-side, but in hill districts, 

 such as Cannock Chase, it assumes a darker brown margin.
