Chrysomelidce, in Linnman and Banksian Collections. 21 



20. Chrys. viminalis (Faun. Suec. 163, 524). It appears to me 

 that this is a singular variety of the Chrysomela {Gonioctenu) vimi- 

 nalis of SufFrian — a variety so rare with us in England, that after 

 looking over a large number of specimens, I have only succeeded in 

 finding one individual presenting the same conditions, and that is 

 in Dr. Leach's Collection. The point that is most striking about 

 the Linnaean specimens is, that the thorax (instead of having a 

 transverse black patch at the base, and which is more or less 

 eraarginated in front) has two smallish black spots in a transverse 

 line behind the middle of the thorax, but distinctly removed from 

 the base. The elytra are immaculate. The legs are entirely 

 black, a character which helps to distinguish this species from the 

 Chrysom. triandrce and Chrys. offinis of Suffrian. The species is 

 represented in the Linnaean Collection by three specimens (two of 

 which are on the label) answering to the above description, and a 

 third specimen which has the thorax immaculate as well as the 

 elytra-. 



21. Chrys. decempunctata (Faun. Suec. 164, 525) = Gonioctena 

 rujipes and G. \0-punctata, Steph. There are three specimens 

 stuck on the label bearing the name : the first is the G. rtijipes, and 

 the other two are the Gon. \Q-punctata of Stephens (= viminalis, 

 Suffr.), agreeing with our British specimens in their more common 

 condition. 



22. Chrys. Lappomca (Faun. Suec. 164, SZQ^ = Lina Lapponica. 



23. Chrys. Boleti (Faun. Suec. 165, 527) = Diaperis Boleti. 



24. Chrys. collaris (Faun. Suec. 165, 528) = Lina, id. 



25. Chrys. hcemorrhoidalis (Syst. Nat. 587, 6). A species of 

 Gonioctena I am unacquainted with ; of a pitchy black colour, 

 with the inflected margins of the elytra rufescent. I suspect the 

 var. i. of Gyllenhal's Chrys. dispar will be found to agree with the 

 Linnaean specimen. 



26. Chrys. sanguinolenta (Faun. Suec. 165, 529). Upon looking 

 through the description of C sanguinolenta given by M. Suffrian, 

 soon after having examined the Linnaean specimen, I am inclined 

 to think that the species described by that author is identical with 

 the Linnaean one, but the disc of the thorax in the Linnaean insect 

 is smooth. Upon comparing the two British insects, C. sanguino-
