334 The Insect Fauna of Van Biemenh Land. 



jecting but little from between the segments of tbe third 

 limb j the antennae moderately long^ tliin_, the last joints 

 rather broad. A new species from Van Diemen's Land,- 

 with two New Holland species^ is described below. 



Of Galeruca only one new, wingless species has been 

 found. Of HalticcB three species, one of which, H. (Grap- 

 toderaj corusca is nearly related to our H. oleracea (*), 

 the second is a new species belonging to Psylliodes, a genus 

 limited almost exclusively to Europe ; the third species is 

 also new, audit belongs to the genus Arsopoda,((\) , which 

 is peculiar to the Fau.na of New Holland. 



The family of Erotylidi, which unites so naturally with 

 Chrysomela on the one hand, and with Coccinella and En-- 

 domychus on the other, contains besides those forms ar- 

 ranged under Erotylus, Triplax, and Languria, also Engis. 

 Why Dejean^s genera Encaustes and Episcapha have been 

 separated from this family, I cannot tell ; they agree with 

 it in the formation of the feet and palpi, more closely than 

 Engis does which has both simple feet and palpi and yet is 

 rightly placed in this family. To E^igis assimilate three new 

 species, ( I do not knov/ any others,) of a A^an Diemen's 



(*.) A second species from V. D. Land is H. Australis, M. Leay; which Dejean places' 

 in his catalogue (with many other species) as a variety oiH. oleracea, 



(+.)Waterhouse (Transact, of the Entomol, Sec. of London I [. p. 131) describes l6 species 

 of New Holland Halticce, but he does not define them very accurately or systematically 

 Due of them, H. variegata, is from V. D. Land ; another is said to be nearly related to 

 ll.nemorum; a.t\m<!Lhe\oxigs to PsylUodes, (Macronema), five are Diholiae{'>), but I 

 think these last ought more properly to be classed with ricctroscelis, Chevr., one of 

 the most widely distributed forms.
