 2. Descriptions of unrecorded Species of Australian 



COLEOPTERA OF THE FAMILIES CaRABIDjE, BuPRESTIDiE, 



Lamellicornia, Longicornia, ETC. By Adam White, 

 Assist. Zool. Depart. Brit. Mus. 



(Annulosa, PL LVIII,, LIX.) 



Catadromus, Macl. 



Catadromus elseyi. (PI. LVIII. fig. 3.) 



C nitido-ater ; thorace elytrisque viridi marginatis ; thorace 

 postice suhquadrato ; pectore ante propedes, lateraliter viso, 

 recto ; elytrorum basi, ad suturam, et pone scutellum, utrinque 

 quadri-pnnctata. 



Hob. In Australia boreali. 



This fine Beetle was found on the Upper Victoria, Australia, in 

 lat. 17° 30' S.,in April 18.56, by the lamented Mr. Elsey, the Surgeon 

 of Mr. Gregory's famous Exploratory Expedition. It is as large as 

 Catadromus tenebrioides, Macleay (Ann. Jav. p. 18, Carabus t., 

 Oliv.) ; the pectus, as in that species, is notched deeply in one sex, as 

 Mr. Ford's admirable figure shows, less deeply in the other. It is 

 an insect with the same long elytra as in that Javan species and in 

 the Australian C. australis, differing from the C. caraboides from 

 Australia, in which the elytra are much shorter. 



Platysma. 

 Platysma sturtii. (PL LVIII. fig. 1.) 



P. nigerrime Icevigatum ; thorace antice latiore quam longo ; 



elytrorum lateribus basi et ante apicem dilatatis ; dorso sul- 



cato-striato, interstitiis depresso-convexis. 

 Hab. In Australia interiore. 



Mr. Bakewell kindly gave to the Museum this species : it was found 

 with the following, after a violent flood, and was washed from the 

 plains of the interior into the province of Victoria. I have given 

 to it the name of the great Australian explorer, Capt. Sturt. 



Platysma flindersii. (PL LVIII. fig. 2.) 



P. thorace elongatulo, lateribus rectiusculis ; elytrorum basi ca- 

 rina abbreviata, lateraliter extensa. 

 Hab. In Australia interiore. 



Found at the same time as the last. Both seem to be females, 

 and nearly resemble each other : the thorax in this is much more 

 elongate, the shortish outstanding keel at the base is not extended 

 so far down the elytron at the side as in the last ; but the general 

 flattened character of the elytra and their dilated hind margin nearly 

 agrees with it. They may 5e sexes of the same species. The first joint 

 of the antennse is longer than the rest, somewhat as in Trigonotoma. 

 I have named it after Capt. Flinders, the great Australian navigator, 

 whose naturalist was "Robertus Brown, Botanicorum facile prin-.
