86 NOTES ON AUSTRALIAN COLEOPTERA, 



own collection contains several moi'e also allied to Amhlytelus. 

 On these I find it necessary to form two new genera characterised 

 below. The following tabulation will show how these genera are 

 related : — 

 A. Penultimate joint of tarsi bilobed. 



B. Prothorax with two marginal punctures on 



either side Amhlytelus. 



B. Prothorax with only one marginal puncture 



on either side Dystrichothorax. 



A A. Penultimate joint of tarsi not bilobed Epelyx. 



Amblytelus. 



The following is a tabulation of the described species of 

 Amhlytelus. I have placed A. vittatus, Motsch., merely from the 

 description, as I have not seen any insect agreeing with it. It 

 appea rs to be a very small species resembling A . curtus, Fab., in 

 style of markings but with the testaceous margin of the elytra 

 extremely narrow. 



A. Each elytron (separately) bearing a pale 

 discal vitta. 

 B. The pale vittfe widely confluent in the 

 front part of the elytra. 

 C. Prothorax much narrower at base than 



at front margin sinuatus, s)).nov. 



CO. Prothorax very little narrower at 



base than at front margin brevis, sp.nov. 



BB The pale vittae not confluent in front i . ' ^l , 



{ vittatics, Motsch. 



AA. Elytral markings consisting of a large 



common pale blotch discoidalis, Black b. 



AAA. Pale elytral markings narrowly limited 



to the suture and lateral margins... mornatm, Blackb. 



AAAA. Elytra without distinct markings 



(size very small) minutus, Macl.
