20 Mr. G. R. Waterhouse's Notes on 



6. Chrys. hcemaptera (Faun. Suec. 161, 512) = Crys., id. 



7. Chrys. Padi (Faun. Suec. 161, 513), Upon a former occa- 

 sion I took this insect to be the Cyphon Padi, but upon cleaning 

 the specimen a little, I perceive that it has two or three faint costae 

 on each elytron, a character by which I am in the habit of dis- 

 tinguishing the Cyphon coarctatus, of which it is a smallish variety. 



8. Chrys. armoracece (Faun. Suec. 161, 515) = Phcedon coch- 

 lear'iis (of Gyllenhal) = Betulce, SufFrian. The elytra of the insect 

 are delicately punctate-striated, with the interstices finely, but 

 pretty distinctly, punctured ; they have a distinct impression 

 within the humeral hump, and are of an obscure greenish colour. 

 It was compared with our common blue Ph. BetulcB, Steph. 

 (^=. cockle ari<£, Suffr.), from which it differed not only in having 

 the humeral impression more distinct, but in being broader and 

 less convex, and in having the interstices of the striae of the elytra 

 distinctly punctured. 



9. Chrys. cerealls (Syst. Nat. 588, 17) = Chrys., id. 



10. Chrys. fasluosa (Syst. Nat. 588, 18), Chrys., id. 

 n. Chrys, halensis (Syst. Nat. 589, 20), Agelastica, id. 



12. Chrys. vul gatissima (Faun. Suec. 162, 517), Phralora, id. 

 = Phcedon unicolor, Steph. 



13. Chrys. vitellince (Faun. Suec. 163, 519), Phratora, id. 



14. Chrys. PoUgoni (Faun. Suec. 163, 520), Gastrophysa Poly- 

 goni. 



15. Chrys. pallida (Faun. Suec. 163, 521), Gonioctena, id. 



16. Chrys. Staphyka (Faun. Suec. 163, 518), Chrys., id. 



17. Chrys. polita (Faun. Suec. 163, 522), Chrys., id. 



18. Chrys. lurida (Syst. Nat. 590, 28), Chrys., id. 



19. Chrys. Populi (Faun. Suec. 163, 523), Lina, id.
