333 The Insect Fauna of Van Diemen's Land. 



naturally arranged^ as^ for example^ Australica Chevr. (*) 

 a lorm limited and peculiar to New Holland. Ch. Curt- 

 isii (t) and Ch. maculicollis (J) have been forwarded from 

 Van Diemen^s Land. Another peculiar form with two 

 species^ Chr. constricta and pacijica has some resemhlance 

 to our Helodes in the pointed palpi ; but diflPers from it in 

 the clamsj which are toothed at the root. A third widely 

 distributed form is Dejean's Phaedon, which also presents 

 two new species. 



Of three new Colasjji, not one is peculiar to New Hol- 

 land ; one belongs to the typical genus Colaspis, so remark- 

 ably numerous in Anierica_, though deficient in other parts 

 of the world : the other two belong to the genus placed by 

 Che^Tolat inDejean^s catalogue under the name of Odonti- 

 onopa ; it is easily distinguishable by an appendage resem- 

 bling two little teethj which is affixed to the anterior part 

 of the head. 



Among the Crypto cephali, the form now regarded as 

 typical, and which is more or less universally distributed. 



(*.) This genus has the palpi and the simple bands of the typical Chrysomeles 

 but its claws are strongly toothed to within a short distance of the tips. The 

 antennae are compressed from the sixth joint upwards. With respect to the name we 

 should scarce'y imagine that another branch of Zoology contains a similar one ; and 

 yet Lesson has an Australasia : Entomologists however, reject this name for the insect 

 genus, as do ornithologists for the parrot genus [Triclioglosstis Horsf,), Hope (Col 

 Manual III, p. l66.) proposesfor this Chrj'somela-form the new appellation of Calomela, 

 a name which wou'd always remind us of calomel.
