50 THE ENTOMOLOGIST. 



I reared a fine series of this species from larvae collected from 

 furze-bushes, at Waustead, the middle of June: the larva3 

 fed under webs, which are generally placed on stems of some 

 years' growth, and are consequently difficult to collect; I 

 used a strong pair of cutting-pliers for cutting out those 

 portions of the plant containing the webs, which should be 

 disturbed as little as possible. Aiiarsia spariiella. — Bred 

 freely from larvae collected on the furze-bushes with the 

 above mentioned. Depressaria coslosclla. — I reared this 

 species in profusion, in July, froui larva; found on the 

 three following plants : Ulex europceus, Sparlium scoparium, 

 and Genista atujlica; those reared from the latter plant are 

 the most beautiful, many being a rich pale brown. Coleo- 

 pJtora genislcecolella. — I found the larvas of ihis somewhat 

 local sjiccies tolerably abundant last June, on Goiisla 

 anglica, in Epj^ing Forest, and about fifty moths emerged 

 during July and August. C. virgaureella were reared in 

 profusion in August, 1876, from larvae collected from the 

 seed-heads of golden-rod {Soiidago virgauren) in November, 

 1875: they are easy to rear, if kept exposed to the influences 

 of the weather. — W. MA(miN ; 2-2, Argyle Road, Carlton

DouBLE-BKOODEU INSECTS. — On August 7, 1868 (an early 

 year), 1 first took an autumnal specimen of LobopJtura 

 t'irelata. On mentioning tlie circumstance to Mr. Bond, and 

 other practical entomologists, 1 found they were already 

 aware of the fact of its occurring twice annually. In the 

 same way Fidonia conspicuaia, Hadena alriplicis, and many 

 other species, are double-brooded : but we must follow up 

 Nature in the fields, and in the woods, to ascertain what 

 species are naturally so, and not trust to books. I do not 

 fancy Papilio Macluxon is strictly double-brooded, like Agro- 

 pliila sulphuralis^ which keeps coming out all the summer 

 through. In the autumn of 1871,1 collected about six dozen 

 larvae of P. Machnon, all just full fed ; the pupa) were all kept 

 during the winter and spring in precisely the same condition ; 

 the first butterfly emerged on the 18lh of May, 1872, and the 

 last on August 10th, the greater number during the third 

 week in June. — Battersiiell Gill; i), Cambridge Terrace,

Abundance of Larv.e. — I have noticed this autumn an 

 unusual abundance of the larvae of Pieiis Brassicce. The
