This genus, which is specially abundant in the Indo-Malayan 

 region, has but few representatives in Australia. 



It belongs really to the tribe Bryaxini, having one single tarsal 

 claw, but it has more the general appearance of the Batrisini. 



The type of the Australian species is Bryaxis Armitagei, King, 

 which Dr. Schaufuss took to be a Batrisus. 



In the Rev. d'Ent., 1882, 1 established the genus Batrisomorpha 

 for some new species of the Indo-Malayan region and of New 

 Guinea, and I included in it Bryaxis Armitagei, King, but Mr. 

 Reitter had created previously the genus Batraxis tor a European 

 insect from Greece which proved to be generically identical, and 

 the name Batrisomorpha is therefore synonymous with Bat axis. 



The maxillary palpi are rather elongate, with the last joint 

 fusiform; the intermediate coxse are approximate and the posterior 

 ones much less distant from each other than is usually the case 

 amongst Bryaxini ; the antenme are strong, with the club 

 evidently two-jointed; the prothorax is devoid of sulci, the elytra 

 have no dorsal stria; the first dorsal segment of the abdomen is 

 very large, more or less, but always briefly carinate on the sides 

 -at the base and without lateral margin.
