 I have not been able to satisfy myself as to the validity of the 

 characters of the Australian genera which Mr. Bates has 

 characterised near ^Ethyssius (Atractus). The shortness of the 

 apical joint of the antennae seems to vary with the sex, and also 

 with the species ; nor do I find the slight elongation of the second 

 joint of the maxillary palpi at all a workable character, as it 

 would lead to the separation into different genera of species that 

 are (even as species) very closely allied. In the present insect 

 the apical antennal joint is in one sex not, and in the other 

 scarcely shorter than the tenth joint; indeed, I cannot find much 

 to distinguish the insect from ^Ethyssius. It, however, resembles 

 A. brevico'niis, Bates, too much in general facies to be separated 

 from it generically, in the absence of strongly-marked characters. 

 The species of this genus have much superficial resemblance to 

 Leptura.
