THE ENTOMOLOGIST S RECORD. 



having tlw central fascia broken into two blotches, costal and inner- 

 marginal, paralled to the var. of mciata with the same name. Has 

 this well-known form been already described earlier ? '^' 



M. finctuata, Linn. — lam working up this species for a paper to be 

 read before the City of London Entomological and Natural History 

 Society in April. Can any reader inform me whether the var. 

 incanata, Renter {ride., Knt. Rec, y.,]).2n) had, as suggested, "been 

 before described as var. vinjata,'" and if so where, and by whom? The 

 variety in question is that with the central band prolonged across the 

 entire wing. [Was this described by Mr. Cockerell '? Ed.] 



Coremiaspadicearia, Bkh. [fern(<iaria, Hw.) var. contid-aria,'ii.S.,Sdi 

 (ride., Ent. liee., v., p. 120). — i am able to announce this interesting 

 form as British ; I detected (and secured) a specimen at the recent 

 sale of Mr. Robson's collection ; it was in the series of unidentaria, 

 and figured in the catalogue as " a very fine variety " of that species ; 

 it is labelled " W. Reid, Pitcaple, 1892." 



* It is not unlikely that Staudinger's var. (et ab.) lapponica (" minor, dilutior, 

 al. ant. fascia media dissoluta "), which I have not yet seen, includes this form ; in 

 that case the new name will of course sink. 



How Colias edusa Winters. 



By J. W. TUTT. F.E.S. 



In Newman's British Bittterjlies (p. 145), we read of Coliaa 

 rdufta: — " Time of Appearance. — August, September, October and 

 November : it hybernates, but very frequently perishes before the 

 spring ; the survivors re-appear in May and June." Stainton gives 

 "end of August to the middle of October" for the imago, and 

 " middle of June to end of July " for the larva. He says nothing of 

 how the butterfly passes the winter. Newman's Briti-'^h Buttei-Jiies 

 has proved such a help to the collector, it has enabled him to name 

 his captures so readily, that he has been willing to accept every 

 statement in it as gospel. At least, that is the only explanation I 

 can venture to give as to why Ave all agree with Newman's dicta, and 

 stare in amazement at a contrary opinion. But in the Eiit. Mo. Mai/., 

 vol. xiv., pp. 150-151, Mr. Barrett expressed the opinion that <'. ediim 

 did " nothybernate in the perfect state." From larvie obtained from 

 eggs laid in August, 1877, Mr. Buckler got pup* in October, but we 

 do not, I believe, hear what became of the pupse, but I do know 

 from personal observation that just about the time and just after 

 these larvae had pupated fresh females were flying in the fields, and 

 were egg-laying. Mr. C. G. Barrett captured a female ('. edimi near 

 Pembroke, which on October 12th laid some eggs, which Mr. Buckler 

 received the following day, and from which larvte emerged on October 

 27th. It was not until November that these late females were killed 

 off, and, until they were, they continued to lay eggs. My recent 

 consideration of the rationale of hybernation has led me to conclude 

 that female butterflies which lay eggs in the autumn die and so do not 

 live through the winter. 



Wc do not learn, as I have remarked, what became of Mr. 

 Buckler's pup^e that he obtained in 1877, between October 15th and 

 October 27th, nor of the larvtB which hatched on October 27th of the 

 same year, but in the E. M. M., vol. v., p. 77, the late Mr. C. W.
