18 Mr. G. R. Walerhouse's Notes on 



II. 'Notes on ChrysomelidsB in the Linnczan and Banhsian 

 Collections. By G. R. Waterhouse, Esq., V. P.Z.S. 



[Read Nov. 5th, I860.] 



Having at distant periods twice examined the species of Chryso- 

 melidce in the Linnsean Collection,* and having again looked 

 through the collection, with considerable care, within a few days, 

 it has been suggested by a friend that my notes might be accept- 

 able to the Society. I therefore beg to lay them before this 

 meeting. I have quite recently also examined many of the Cliry- 

 somelidce in the Banksian Collection, which it is supposed was 

 named by Fabricius. However this may be, it is certain that he 

 overlooked the specimens, and described many species from the 

 Banksian Cabinet. The specimens in this last-mentioned collec- 

 tion are many of them in very bad condition, and require cleaning 

 before they are capable of a very accurate examination; at the 

 same time I think my determinations will be found generally cor- 

 rect. The Linnaean specimens, considering their age, are generally 

 in good condition. I have examined only those which have the 

 labels attached to them — labels which are said to be in Linnseus's 

 own writing. I will take them as they stand in the collection, and 

 it will be seen that they follow nearly in the same order as do the 

 descriptions in the "Fauna Suecica." I will here observe that the 

 species of the " Fauna" are generally well represented in the col- 

 lection, but of those subsequently described in the "Systema" I 

 find but a small number. 



1. Chrysomela Gottingensis (Faun. Suec. 160, 505). Two dif- 

 ferent insects, each bearing the same name, but with separate 

 labels, stand to represent the species. The first is the Chrys. 

 Gotlingensis of modern authors, and the second is the Timarcha 

 coriarla. This last-named insect also stands in the Banksian Col- 

 lection as Chr. Goltingens'is. 



2. Chrys. Tanaceti (Faun. Suec. 160, 507), Ad'imonia, id., of 

 modern authors. "[■ 



* My first examination was in September, 1857 ; and I again examined the 

 collection last year. 



f I will not repeat this phrase hereafter — let it be understood, that the names 

 given in the second column are those now in common use.
