FAMILY XI. STAPHYLINIDJE. 



widest at middle; sides strongly rounded, sinuate near base, hind angles 

 rectangular ; disk coarsely and rather closely punctured, with a deep me- 

 dian impressed line and a fovea at middle of base. Elytra at base slightly 

 wider than thorax, reaching to fourth segment of abdomen, coarsely and 

 rather densely punctate. Abdomen rather finely and sparsely punctate. 

 Length 6.5-8 mm. 



Southern half of State, scarce ; Lake County only in the north. 

 May 11-October 20. Occurs beneath stones, moss and leaves in 

 damp places. Usually listed as tcesus Eriehs., but Say's name has 

 priority. The thorax varies much in size and in the depth of the 

 sinuation behind middle.

Form of hrunneus. Black, shining; antennas and legs and often the 

 tip of abdomen, reddish-brown. Head narrower than thorax, front triangu- 

 lar, narrowly impressed between the eyes, finely and sparsely punctate. 

 Thorax subcordate, wider than long, sides strongly rounded, deeply sinuate 

 behind, the base much narrower than apex ; disk finely and rather closely 

 punctate, the median line shallow. Elytra at base equal in width to tho- 

 rax ; surface, as well as that of abdomen, finely and rather closely punc- 

 tate. Length 5.5-6 mm.

Small, flattened species, having the third joint of maxillary 

 palpi very small, not longer than wide, the fourth joint very long; 

 thorax (in our species) not flattened on the sides ; first joint of hind 

 tarsi not quite as long as second. 



919 (2803). Lesteva pallipes Lee, N. Sp. N. Amer. Col., I, 1863, 55. 

 Elongate-oval, depressed. Blackish-piceous to dull brownish-yellow, 



feebly shining, sparsely clothed with yellowish hairs; elytra when piceous 

 each with an oblique pale spot extending from humerus to suture. Head 

 with two deep, oblique impressions, rather densely and finely punctate. 

 Thorax subcordate, slightly longer than wide, widest in front of middle, 

 the sides thence oblique and sinuate to base; disk finely and sparsely punc- 

 tate and with two distinct, shallow oblong impressions on basal half. Ely- 

 tra at base one-half wider than thorax, thence feebly widening to apex, 

 covering one-half or more of abdomen, finely and sparsely punctate. Abdo- 

 men as wide as elytra, broadly margined, very finely punctate. Length 

 3-4 mm. 



Marion, Putnam and Crawford counties ; frequent locally. May 

 11-October 17. , Taken by sifting vegetable debris from about hill- 

 side springs. Probably occurs throughout the State. One speci- 

 men was found crawling on the floor of Wyandotte Cave nearly 

 one mile from the mouth.
