Seems to be near Osorius which however has live-jointed tarsi. 

 The tarsi of this new genus consist of two extremely short Joints 

 and a third very much longer than the others together. I am 

 not quite sure that there is not a very minute joint before that 

 which appears to me to be the basal one, and I could not resolve 

 the doubt without damaging my unique specimen. There are, 

 however, at an}^ rate only three joints that can be distinguished 

 under a Coddington lens. The insect for which I propose this 

 name is very easily recognisable as an Osoriid with less than live 

 tarsal joints and with front tibiae resembling those of a Scaritid.

I have been especially careful to describe this insect very fully 

 •on account of my not having been able to define with certainty
