Mr. J. Walton on the genus Rhynchites. 87 



a variety of this species, I called Dr. Germain's attention to the 

 point, and in his notes he observes, " I agree Math yon in opinion 

 that the R. Fragarice is a blue variety of the (eneovirens of Mar- 

 sham." Dr. Germar has sent me a foreign specimen of the Fra- 

 gari(2. 



The blue-green varieties (the small males having the rostrum 

 short) veiy much resemble, and may easily be mistaken for, the 

 same coloured varieties of No. 8 ; however, this species is distin- 

 guished by having the body densely covered with long erect cine- 

 reous hairs. No. 8 is sparingly clothed by short subdepressed 

 fuscous pubescence. 



This species is found in the month of May upon the oak as soon 

 as it begins to bud. 



13. R. cupreus, Auctorum. 

 Cure, cupreus, Mus. Linn. 



I am indebted to T. C. Heysham, Esq., of Carlisle, for the sexes 

 of this rare and beautiful species, who kindly sent them alive in 

 a pill-box by letter ; he found them on the mountain-ash [Pyrus 

 aucuparia) in the beginning of June.

 R. Betulce, Steph. 

 Att. Betuleti, Mus. Kirb. 



It becomes necessary to follow those authors who use the Fa- 

 brician name Betuleti for this species to prevent confusion, Lin- 

 nseus having given the name BetulcB to another insect as well as 

 to the present one, and that insect is by many authors regarded 

 as a member of the genus Rhynchites. 



15. R. Populi, Auctorum. 



C. Populi, Linn. Mus. Linn, 

 Att. Populi, Mus. Kirb. 



I have taken this insect in the month of June in Darenth Wood 

 from the young shoots of the Populus tremula. 



At Colney Hatch Wood Mr. Smith has taken this species from 

 the same plant in great abundance, and invariably found, by see- 

 ing them in copula, that the specimens \\dth the spine on the side 

 of the thorax were the males.
