Rediscovered or new British Coleoptera : Nemosoma elon- 

 gatinn^ Hydroporus neylectus, Helophorus nanus, 

 PIn/lubius 4-nodosus, Ilybias subceneus, igc. By John 

 A. Power, M.D. 



I HAVE recently liad the pleasure of rediscovering two very 

 rare insects, which had, as it were, vanished for between 

 thirty and forty years, so t'nat I iinJigine few British Ento- 

 mologists have seen them alive. 



The first is Nemosoma clongatum. It was taken in con- 

 siderable abundance by Messrs. Ingall and Westwood, in an 

 old elm-rail near Sydenham, about the year 1830. In the 

 year 1833 Mr. Ingall gave me sundry specimens, and from 

 his slock the insect has got distributed on points, or pinned 

 through all the old collections, but has always been con- 

 sidered raro. Since this time I only know of three specimens 

 being taken, one by myself at Sydenham, whilst actually 

 talkiuij of the insect, and two by my friend Mr. De Rivaz. 

 I may safely say that for the last twelve years I have seldom 

 observed an elm-rail without thinking of Nemosoma. 



Last Easter I was on a visit to an old College friend, the 

 Rev. Jas. Gorle, of Whalcote, near Shipston-onStour ; and 

 on Easter Monday we had a fishing expedition to a glorious 

 old place about two miles distant, Com})tnn Wynniat, be- 

 longing to the Marquis of Northampton. The house is a 

 grand example of the style of about Henry VII. : there are 

 iish-stews, moats, &c., peacocks both alive and clipped 

 out of vew and box-bushes, &c. The house, one of the 

 noiabilia of Warwickshire, is kept in good condition by the 

 Marquis, who occasionally retires, like a sensible man, to the 

 quiet of this sequestered spot. Whilst my Triend Gorle, with 

 his sons and daughters, were fishing, without much success, 

 in an east wind, " good neither lor man nor beast," though 

 we have sometimes caught some grand perch, &c., at this 

 place, I was hunting about after my favourite Coleoptera.
