about the middle of the head; prothorax always more or less 

 longitudinally sulcate; the shoulders on the elytra are always 

 more or less dentate or at least notched; the first dorsal segment 

 of the abdomen is only a little larger than the following unes 

 which are very conspicuous and not abruptly declivous, the first 

 one bears always on the side two carinules at least at the base, 

 the body is elongate. 



Even when so restricted, the genus Batrisus includes a large 

 number of species very irregularly distributed in the different 

 parts of the world. Although very numerous in the Indo- 

 Malayan region, it seems rather scarce in Australia.
