 sensim acuminata, post medium prothorace dimidio latiora, 

 supra plana, postice abrupte declivia, dense albido-flavescente,

Shape and size of P. alboiwtatits, but whereas in P. haacji there 

 are three denuded granulose lines, besides the outer margin on each

 in the first-named species, and these lines are also setulose.
