Four specimens were found. It is not impossible that these belong to 

 another very closely related species, but a longer series is necessary to determine 

 whether this is so, or whether P. nitidicollis, only previously recorded from 

 Ceylon, is a widely distributed and somewhat variable form.

 Their close relationship cannot be doubted, for 

 it extends not only to the almost identical character of the pecuUar spines 

 studding the surface, which are not pointed but truncate at the ends, but even to
