There appears to be two broods of this butterfly, the one appearing in May 

 and the other in August. Possibly there are three broods, as the butterflies 

 may be found from the end of April to the beginning of October. The 

 caterpillars seem to hybernate in various stages of growth, and might prob- 

 ably be found all the year round. The Rev. J. Hellins had some eggs laid 

 by captured females on May 28th, 1874. On August 11th one caterpillar 

 had become a chrysalis. On August 22nd the butterfly appeared, whilst the 

 rest of the brood were still caterpillars, and just then passing through a 

 moult ; and these hibernated in the caterpillar state. 



Ccenonympha pamphilus frequents all sorts of grassy places, heaths, railway 

 banks, dry pastures, grassy lanes, &c, and is distributed all over Europe, 

 except in the extreme north, and is found also in Asia and Northern Africa. 

 It is distributed all over the British Isles, except the Orkneys and Shetlands, 

 and is as yet the only species of butterfly reported from the small and far 

 away Isle of St. Kilda, — 



" Whose lonely race 

 Resign the setting sun to Indian worlds." 



St. Kilda is the most westerly of the Hebrides, being 80 miles west of the 



Butt of Lewis. 



Pamphilus was described as British as long ago as 1667, in the " Pinax" 

 of Dr. Merrett. 



It is recorded in Kay's " Historia lnsectorum," 1710, as being very fre- 

 quent in meadows through nearly the whole season. 



Genus XIV.— EREBIA. 

 Dalman, 



Ereb'ia, from Erebus, the region of darkness : in allusion to the dark 

 colours of the butterflies contained in the genus. 



The name generally adopted for the present genus was proposed by Dalman 

 for the whole of the Swedish species of Satyridse ; it is consequently a syno- 

 nym of Uipparchia and Satyrus ; as such it was rejected by Professor West- 

 wood, who proposed the name of Oreina in its stead, in allusion to the 

 mountainous habits of the genus. 



The species are very numerous, and are subject to great variations. They 

 are distinguished by having the principal veins of the fore-wings either not 

 swollen, or the costal vein alone slightly dilated at the base. The hind- wings 

 are generally entire in the smaller species, and slightly dentated in the larger. 

 The palpi are covered with long bristly hairs, and the antennas are slender, 

 with a rather long club. The caterpillars are covered with fine scattered 

 hairs, and in shape are pisciform, like the rest of the family. The genus con-
