6824 Insects. 



A List of the described Longicornia of Australia. 

 By Francis P. Pascoe, Esq., F.L.S., &c. 



The following list of the longicorn Coleoptera of Australasia has 

 been drawn up in order to show, at one view, the extent of that 

 portion of its insect-fauna, so far as it is known at present; and also 

 with the hope of calling the attention of naturalists to the desirableness 

 of such lists generally. The frequent re-issue of the Botanical 

 Society's 'List of British Plants' and the four Catalogues of European 

 Coleoptera, one of which has gone through eight editions, sufficiently 

 attest their utility ; and it cannot be doubted, especially in the present 

 diffused and disjointed state of zoological and botanical literature, that 

 an extension of this class of small books would be a great boon to the 

 student of natural science, and particularly to the investigator of the 

 geographical distribution of species. 



There are about four hundred and twenty longicorns natives of 

 Europe ; the present list contains the names of two hundred and 

 fifty-nine : looking to the nearly equal areas of the two regions, the 

 more favourable climatic influences of Australia, and that our collec- 

 tions have been derived principally from the Adelaide, Melbourne and 

 Sydney districts, it may be fairly assumed that we are not yet 

 acquainted with one half; as it is, the list might have been consider- 

 a,bly extended by the introduction of the unpublished species in our 

 cabinets. 



The localities given in this list are only such as could be fully 

 relied^ on, but it is interesting to mark the wide diffusion of many of 

 the species, notwithstanding we find that only two of them extend to 

 New Zealand (Phoracantha dorsalis and Brachytria latebrosa), and 

 one only (Phoracantha biguttata), if we except a doubtful Xystrocera, 

 to New Guinea. Moreover, there are only two genera common to, 

 and confined to, Australasia and New Zealand (Microtragus and 

 Phlyctaenodes), and two, in like manner, to Australasia and New Guinea 

 (Meton and Symphyletes). Of course these remarks will, probably, 

 have to be considerably modified when our knowledge becomes more 

 extended.
