lHE three genera of Passalidae, which form tlie subject of this 

 paper, belong to the sub-family Onaphalocneminae (see Gravely. L913). 

 During a visil to the Hamburg Naturhistorisches Museum I have 

 been engaged on a revision of the genera of this subfamilj ; and I have 

 to thank Prof. KEAEPELIN and the st äff' of the Entomological section oi 

 this museum for their kindness in permitting nie t<> work there, and giving 

 me free access to all their collections. Through the kindness of the 

 authorities in the Berlin Kgl. Zoologisches Museum, the Deutsches 

 Entomologisches Museum, the Stuttgart Kgl. Naturaliensamm- 

 lung, and the British Museum, 1 have received from these museums 

 üiir series of specimens of Onaphalocneminae for examination. and 1 take 

 tili-; opportunity of thanking them for their help. 



For a complete revision of the species of this subfamily much more 

 time that I can at present devote to it would be needed. But as a new 

 genus is required for the species trigonophonis, ZANG, which was doubt- 

 fully referred by its author to the genus Kaupiolus, a fuller description 

 of this than has yet been published appears to be ealled for. The genus 

 Hyperplesthenus, KUWERT, is also very imperfectly described, so much so 

 that HELLER bas failed to recognise in the species gracilis, which he 

 doubtlüUy referred to the genus Labienus, KAUP, another member of it; 

 so as I have before nie the types both of KlJWERT's and of HELLER's 

 species, as well as a specimen of a new species. it seems desirable that 

 all three forms should be described t.ogether here. And to the account 

 of these two genera 1 am adding an account of the small genus Omegarius, 

 KUWERT, bf which I have before me examples of both the known species, 

 neither of which has yet been adequately described.
