The Insect Fauna of Van JDiemen's Land. 327 



trunk-beetle presents all the characteristics ascribed by 

 Scbonherr to his genus NotiojjJdhis . {^) One of the most 

 remarkable and peculiar forms is EacJdodes sj/inicoUis 

 Sehonh. (t) : three other less remarkable insects of this 

 division form an equal number of new genera ; ( f these 

 Cryptoplus is related to Anoplus ; Meriplms, with much of 

 the appearance of AntJionomiis, is closely allied to ErirJdnus ; 

 and Diapelmus, with exactly the appearance of Erirhinus ; 

 Dorytomus is intimately connected with Antlionomus. The 

 group of CryptorliyncJii appears to be very extensive^ and 

 presents unmistakeable American forms : of thirteen new 

 species eight belong to Cryptorliynclms ; three to Acalles ; 

 two^ having the snout-groove not closed behind^ form new 

 genera, of which one, Melanterms, corresponds to the 

 American genus Ckalcodernms ; the other Cyllor/ianiphts 

 stands apparently in a similar relationship to Cypliorliynchus 

 Sell, but in reality it belongs to a different division. 



We have not received any species of the group Calandrce 

 so widely distributed elsewhere : the Cossonida, have 

 afforded us two new species of RJiyncohis. 



To this family belong also the bark-scarabs of two new 

 species received by us_, one is a Tomicus (Bostriclms Fabr.^ 

 and the other belongs to the genus Crypliahis {%), of which 

 hitherto, with the exception of Or. tilice, we were acquainted 

 only with European, pine-inhabiting species. 



The number of Latreille^s Xylopliagi will be much reduced 

 by the absence of the bark-scarabs, of the ^j^Mz^e with i/yc;^2<5, 

 the TrogositcB with Rhyzophagus and Nemosoma, the 

 Lathridii with Dasycerus Monotonia and Pausstis, all of 



(*) This name cannot be employed, on account of the similarly caUed Carahus genus, 

 we might change it to Notionomus.
