COLIAS TI., TTI. 



It is prohalilc tluit in sonu- disti'iets, and especially in tlu' more southern States, 

 the l>iitti'illy also sometimes hvbernates, as Edusa and IhjaU are said to do in 

 Euro]H". On 12th December ISTo. I saw a male Philodice on the wing at (Joal- 

 hurgh. long after we had snfleri'd from severe frosts and cold weather, and 

 when all butterllies seemed to havi' disapjteared. 



In the Can. Ent. VI.. ]). '.'L'. Mr. ('ou|)('r notices some pecnliarities in Philo- 

 dice on Anticosti. He .says : " 1 took a few specimens last July. It is a rare 

 butterliv on the island, where its hai)its dift'er from those found at Quebec. It 

 is ditticidt to capture. Its flight is rapid and continuous during the occasional 

 hours of its aj)pearance, ami it is only towards the end of July, when the weather 

 becomes cold, that it can easily be approached. AVhen it alights on a llower. 

 instead of being erect on its feet, it lies sideways, as if to receive the warmth 

 of the sun." 



-Mr. lieakirt. in his paper on Coloradan lUittei'tlies, Proc. Ent. Soc. VI.. p. lo5, 

 mentions J^h'dodlce as having been taken in Colorado by Mr. Ridings. This 

 State was thoroughly explored by Mr. Mead, in 1871, and "since that time large 

 collections of l)ntterllies have ])een made by the naturalists of Lieutenant Wheel- 

 er's expeditions, and no examples have l)een taken which can confulently be 

 referred to P/i'dodlce. though a near related species is found, the same which 

 Mr. Reakirt had before him. Mr. Mead agrees with me as to the distinctness of 

 this .species from PliUodUc. 



A very interesting ColUix was brought from ('ape Breton island, in 187"). Ijy Mr. 

 Roland Thaxter. and was described l)y Mr. Scudder in the Proc. Bost. Soc. Nat. 

 Mist., Oct., 1875, as a variety of Philodice, under the name oi Laurentina. It is 

 allied to ])0th Pelldne and Philodice, and. in my opinion, is neartn- the former, 

 and may have originated in hybridism between the two. But it plainly breeds 

 true to its present type, for besides tlu' many individuals taken liy Mr. Thaxter, 

 it has occasionally been taken on the mainland, as stated by Mr. Scudder. I re- 

 gard it therefore as a triic .•species, quite as much so as either of its presumed or 

 possible parents. 



Although Philodice is figured in Stephens, in Swainson, and in Humphreys 

 and Westwood, as having been taken in England, Mr. West-wood remarks that 

 '' its claim to be regarded as indigenous is still denied by several of our principal 

 Entomologists." Stephens speaks of five specimens as having been seen by him 

 in cabinets, and says that " till last summer, it does not appear to have been 

 captured in England for upwards of forty years." It seems to me not improbable, 

 in view of the trade, especially in timber, between Canada and England, that 

 chrysalids of this Imttei-fly may occasionally be carried across the sea. In this 

 way chrysalids of Cuban butterflies have been brought to New York on sugar or 

 molasses lioi!;sheads, as I have verified.
