This fine species was described in manuscript some 

 years ago by de Bormans ; his type was a male, then 

 unique, in the Dohrn Collection, of which the feet and 

 antennae were missing. 



It is a very distinct species, chiefly remarkable from 

 the colour and form of the forceps ; in colour and 

 general appearance it resembles superficially Anccliura 

 mctallica, Dohrn, and, in fact, the females of the two 

 species might be confused, but in the latter the elytra 

 are finely granulated, while they are smooth in 0. 

 nevilli. 



The female is lighter in colour than the male, and 

 smaller ; the colour tends rather to dark-reddish. De 

 Bormans' specimens were somewhat larger than those in 

 the Paris collection. In his notes he gives the following 

 dimensions : length of body, 14 mm. ; of the forceps, 

 1375 mm.
