226 LLOYD'S NATURAL HISTORY. 



well-marked eye with a white pupil and yellow ring on the under 

 surface. The hind-wings beneath are greenish-grey, darkest 

 at the base, with an irregular and interrupted whitish band, 

 and with a few white dots nearer the margins, which, in the 

 South European variety, C. lyllus (Esper), a larger form than 

 ours, have a tendency to form eye-spots. 



The Small Heath is common throughout the greater part 

 of the Palaearctic Region, on heaths and in meadows, and is 

 the only species of the genus which can be called common in 

 Britain. 



The larva is green, with darker dorsal and lateral stripes 

 bordered with white. It feeds on various grasses, and as there 

 is a succession of broods, it may be met with at almost any 

 time between April and September. The pupa is likewise 

 green. 



III. EREBIA SECTION. 



This section includes the mountain Butterflies of the North- 

 ern Hemisphere (Erebia, Dalm.), the Himalayas (Callerebia, 

 Moore), South Africa (Leptoneura, Wallengren), and New Zea- 

 land (Argyrophenga, Doubl., &c.). The two last genera have 

 longer wings than the others, and the last is ornamented with 

 silvery spots beneath. The only genus which needs further 

 notice here is the following :

As Erebia is the name in general use for these Butterflies, 

 and E. ligea (Linn.) is undoubtedly the type, we have pre-
