This specie?, which is remarkable for the close punctua- 

 tion of the thorax, beat's considerable superficial resemblance 

 to Philonthus viridanus, but differs from it in several import- 

 ant particulars. 



It is broader and stouter, the sides of the thorax slightly 

 rounded and converging in front, not almost parallel as in 

 the latter species, and the punctuation of the thorax is also 

 different. In viridanus the legs are also more or less testa- 

 ceous. It is, perhaps, more of the form of P. confertus, but 

 quite different in color. 



Described from a single specimen ( ? ?) in my collection,
