The Insect Fauna of Van Diemen's Land. 331 



Marshy (*) peculiar to New Holland^ is of great importance 

 in the Fauna of Van Diemen's Land ; among seventeen 

 species sent in we distinguish P. morio {■]■), rufipes (J), 

 lineata (§)^ and notata {\\), the remaining new ones are 

 described below ; among the smaller species^ several re- 

 semble the Casidi, in having the wing cases ornamented 

 with shining, golden_, silver, or mother-of-pearl coloured 

 markings ; which though they disappear after death, can 

 be restored temporarily by means of moisture. 



The genus Chrysomela as hitherto described, is divided 

 in Dejean^s catalogue into a series of genera, of which, for 

 example, Zygogramma is formed merely from a certain 

 similarity in its markings ; it must nevertheless be divided 

 into several parts, these to depend on the form of the pal- 

 pi and clams. Oreina must not be separated from Chryso- 

 mela, though irregular in the shape of the last palpi -joint 

 because this and other extreme forms will be connected by 

 intermediate series. Other genera will be more easily and 



(*.) Olivier counts fourteen ; Marsham twenty-four ; Boiscluval in the Faun de 

 I'Ocean, twenty-five ; Dejean, in his last catalogue, twenty ; (this is with the ex- 

 ception of two Siberian species that do not belong here) our own collection, though 

 not particularly rich in the insects from New Hollrtnr!. numbers fifty-seven species, how 

 many more must be fomid in EngUsh collections to which the natural productions of 

 New Holland find so easy an entrance ! 



(+.) Chrysomela morio Fabricius Syst. Eleuth. I. 308. 5. A more faintly colored variety 

 is not uncommon ; it is reddish brown on the upper part of the body, and has narrow 

 blade streaks on the wing-cases, 



(t,) Chrysomela rufipes Fabricius I. c. 439. 41. 



(§.) Notoclea lineata MdssYisxa. Transact of the Lma Soc. IX. 293. Ip. t. 25. £ 19. 

 The streaks on the wing-cases are more yellow than red.
