A single specimen was sent to me by Mr. F. P. Dodd. It can 

 be readily distinguished from its described congeners by its short, 

 robust form; subdentate humeral angles, etc. According to the 

 table of species given by me in these Proceedings, 1899, p.579, 

 its position is beside D. robusta 81.; from which it differs by its 

 smaller size, shorter shape; elytra with five inner striae fully 

 impressed, inner humeral angle sharply marked; pro-episterna 

 decidedly striolate, metepisterna shorter, etc. 

 Tribe SphodPlni. 

 Platynus carteri, n.sp. 



Winged, depressed. Prothorax subquadrate, wider across base 

 (2mm.) than apex(r5mm.); elytra truncate-oval, strongly striate, 

 eighth interstice lightly convex at apex. Tarsi in g stout, de- 

 pressed; anterior tarsi with three basal joints wide, biseriately 

 squamose beneath, fourtli joint not greatly narrower than third, 

 subcordate, subemarginate at apex; posterior tarsi with basal 

 joint finely and sparsely biseriately setose on upper surface, fifth 

 joint setulo.se beneath. Piceons-black ; tarsi, antenna?, and 

 anterior part of head reddish-piceous.
