THE genus Cenonympha contains two of the smaller kinds of the well-defined sub-family 
grouped under the title of Satyridi. The hind wings are not denticulated at the fringed edge. 
The anterior wings have three of the nervures much enlarged or swollen near the base. The 
antenne are annulated with grey and brown. The larve are quite smooth, and shining. 
Cenonympha Davus (the Marsh Ringlet, Nos. 1 and 2). This pretty Heath Butterfly, only 
found in the North, is very variable in its markings, especially in different localities. This cir- 
cumstance led our earlier collectors (at a time when few specimens were found in collections for 
comparison) to imagine that several distinct British species closely allied to Davus existed ; and 
some of the varieties received the specific names, Typhon, Polydama, Iphis, &c., two dark varieties 
being named respectively Hero and Ascanius ; all of which are, I think, satisfactorily proved to 
have been merely varieties of C. Davus. The details of the transformations of this pretty species 
are at present but imperfectly known. It has been taken plentifully in the marshes between 
Stockport and Ashton, and at Trafford, Whitemoss, in the neighbourhood of Manchester, and 
also on some of the marshy moors of Yorkshire ; Thorn Moor and Hatfield Chase, for instance. 
The Pentland Hills and other places in Scotland, are recorded as localities where it has been 
captured more recently. 
Cenonympha Pamphilus (the Small Heath, Nos. 3 and 4). This is one of the commonest of 
our native Butterflies, while its near relative, C. Davus, as we have just seen, must be ranked 
among the rarest. The Caterpillar (No. 5) feeds on several common meadow grasses, but in 
preference upon the Poa annua or the crested Dog’s-tail grass, Cynosurus Cristatus. It is common 
everywhere, in favourable situations. 
The second sub-family of the Nymphalidae, distinguished as the Nymphalidi, contains two 
British genera, Limenitis and Apatura, each represented by a single species, ranking in both 
cases among the most remarkable of our native Lepidoptera, especially Apatura Iris, which may 
perhaps be considered the crowning jewel of a British collection. 
The genus Limenitis, in the perfect state, appears very closely related to Apatura, but is 
distinguished from it by the following characteristics. It is generally of less robust formation, 
and the fore wings are rounded at the external edge instead of being partially concave as in 
Apatura: the hind wings also are more rounded : the more gradual formation of the club of the 
antenne is another good generic distinction. In the larva state the distinction is much more 
marked ; the Caterpillar having several pairs of fleshy spines on the back, each clothed with fine
