348 REVISION OF THE CICINDELIDjE OP AUSTRALIA, 



following notes on the distribution of the tribes found on the 

 Australian Continent. 



Dr. Horn has catalogued the Cicindelidse of the globe under 

 8 tribes, including 38 genera and 1184 species. Of these 8 tribes 

 only one, viz., the Cicindelini, is truly cosmopolitan. The Mega- 

 cephalini is the next most universally distributed tribe, being 

 found in all the great zoogeographical regions of the earth, though 

 the Palaearctic and Oriental Regions have only one species, while 

 not one has been reported from New Guinea or the East Indian 

 Archipelago. The other tribes have restricted ranges as under — 

 Ctenostomini, Neotropical Region and Madagascar; Collyrini 

 and Theratini, Oriental, but spreading to New Guinea; Neoman- 

 tichorini, Neotropical and Nearctic; Paleomantichorini and 

 Platychilini, Ethiopian.

In the enumeration of the tribes, genera, and species given 

 above, the Palsearctic and Oriental Regions receive the benefit of 

 one tribe and genus by the presence of Megacephala euphralica 

 Latr., which seems merely a straggler from the Ethiopian Region; 

 while, in regard to the Nearctic Region, probably the tribe 

 Megacephalini (as there represented bj four species in the south) 

 is merely an invader from the Neotropical Region. If we divide 

 the globe into two parts, one to include Eur- Asia and all North 

 America north of Mexico and the other the rest of the globe, we 

 find (excluding Megacephala from the first division as a southern 



* The number of species is approximate ; the numbers given total 1184, 

 the number catalogued by Horn ; any species that occurs in more than one 

 region has been counted only as belonging to a single region.
