captor. The third perhaps cannot be considered any more authentic 

 than other examples found in old collections. Then the Rev. W. Kirby's 

 collector, Mr. Denny, took it, it is supposed, at Upensee, in the Isle of 

 Ely. Mr. Robertson's specmien at Liverpool adds but little to the 

 evidence, but the accumulation of small facts often make an irresistible 

 whole. Even without Mr. Layard's record, the evidence appears to be 

 enough to satisfy any reasonable person. I have been in correspondence 

 with him upon the subject and his remembrance of the circumstances are 

 perfectly clear and distinct. No shadow of doubt appears in his 

 mind. I have shown elsewhere (Young Nat. V. vi, p. 64), that less 

 than half of the number of butterflies are accepted as British that 

 ought to occur. On the one hand v/e are finding that species have 

 occurred recently or occur yet, that have never till now been considered 

 British; on the other we find that recognised species are extinct or 

 are dying out. Virgauvea is certainly extinct now, but all the evidence 

 shows that it was formerly a native of tins country, and like Dispav 

 and also like Machaon, it lingered longest m the fens and marshes 

 of our land. 



General Notes. 



Chcerocampa Celerio at Halifax. —On Saturday, the ist instant, 

 a fine specimen of this rare Hawk Moth was taken at rest upon some 

 scaffoldmg, raised in front of a shop, in the town of Halifax, by a 

 joiner who was working upon it, and although brought to me in a 

 match box, the damage is exceeJingly iriiiing. I think you will 

 consider the capture worth recording. Edward Ualliday, Akroydon, 

 Halifax, October 6th, 1892. 



Micro larv/e for the Montfi. - The month of November with 

 its keen easterly winds, and occasional raw cold fogs makes collecting 

 at times far from pleasant, but our resoiulioii to be doing must still 

 continue, for during the next few weeks the coUectnig of those larvae 

 feeding in the leaves and stems ougiit now to be completed, as very 

 few leaves remain on the trees and plants after this month, and the 

 dry stems get broken off and scattered by the high vnnds. We have 

 plenty to do now in taking the larva; of various species oi NcpticuUc, 

 and now is the best time for many species (;f LitJiocolktidce, for the 

 bladderydoooking mines of the larva:: of L. lantanclUi in the leaves of 

 the wayfaring tree (Vibnvuinn lantana) are now very conspicuous, and 

 by searching the margins of woods for tlie Jkish Vetch [Vicia scpinm) 

 we shah very probably take tlie larva of L. brnii iclla , which generally 

 mines tlie entire leaflet. In tlie lea\'es of 1\oiicysiickl(\ n\ (• may still
