The Insect Fauna of Van Diemen's Land, 335 



Land genus, Thallis, whicli differs principally in tlie shape 

 of the tongue. 



The proper position of Fhalacrus has yet to be dete^^" 

 mined ; analogous forms of this genus appear to be distri- 

 buted over the whole earth ; a new species from Van Die- 

 men^s Land is described below : — 



Of the family of the Coccinelli. — Two varieties (*) of 

 Coccinella tricincta, Fab. (f) have spread from the East 

 Indies to Van Diemen's Land. C. conformis Dej. {%) is 

 common to Van Diemen's Land and New South Wales. 

 A third species of the typical form is new. (§.) The genus 

 Scymnus of which three species have been forwarded, as- 

 sumes a larger, longer, and more flattened form in New 

 Holland, than elsewhere. In other respects the New Hol- 

 land species are not peculiar ; they have the same number 

 (ten) of antennae joints, which distinguishes Scymnus from 

 other Coccinelli, ( a circunist?ince, which, however, I do 

 not find anyvv^here observed,) — only Corylophus, Leach, (1|) 



(*.) Syst.El. 361, 33. Schoiih. Syn.II. 169, 42. 



(+.) 'a. Rather smaller than its type, the connecthig plate (Binde) behind, the centre 

 shortened, augulaiiy bent. 



h. Only half as large, the suture (Naht) broad and black ; the c. plates behmd the 

 centre not shortened, but more distinctly, angularly bent.

(§.) This new species might belong to the Micraspis of Dejean's catalogue ; I have 

 not however succeeded in determining any varieties of Coceindla, any more than of 



Cheilomenes,
