FAMILY XI. STAPHYLINIDJE. 



P. quediinus Horn. 6 mm. in length, was described from Detroit 

 and Kansas and should, therefore, occur in Indiana.

 Elongate, slender. Black, shining: elytra bronzed; antennae and legs 



pic-eons, the former shorter than head and thorax, joints 5-10 wider than 

 long. Thorax not wider than head, slightly wider than long, not narrowed

 rion. 



P. cephalotes Grav.. length 6-7.5 mm.; P. inquietus Erichs.. 

 length 5 mm, and P. faUaciosus Horn, length 1 mm., all have a 

 range which denotes the possibility of their occurrence in Indiana.

 Rather short, robust. Head and thorax black, shining ; elytra and ab- 

 domen piceous or dark brown ; antennas piceous, as long as head and thorax, 

 joints 4-10 as wide as long, the two basal ones and legs dark reddish-brown. 

 Thorax slightly wider than head, not narrowed in front; dorsal punctures 

 deep, the fourth somewhat distant from third. Elytra slightly wider than 

 thorax, rather finely not closely punctate. Abdomen sparsely and finely 

 punctate. Notch of last ventral of male feeble. Length 5 mm.

 descent, the punctures finer than on elytra. Length 4.5 mm. 



Marion, Putnam and Clark counties; scarce. April 4-October 

 17. The male is easily distinguished from the next by the entire 

 °roove of last ventral : the female has elytra longer, more sparsely 

 punctate and evidently bronzed. Described from Arizona. Speci-
