377 



Throughout the State ; frequent. April 28-December 18. Oc- 

 curs in carrion, decaying fungi and dung. Hibernates beneath 

 partly buried logs near a food supply. 



720 (2132). Staphylinus mysticus Erichs., Gen. Spec. Staph., 1840, 926. 

 Moderately elongate, rather robust. Dark brown to piceous, subopaque; 



tibia?, tarsi, basal joints of antennae and tip of abdomen reddish-brown. 

 Thorax not wider than head, slightly longer than wide, sides nearly straight, 

 base broadly curved. Elytra a little wider than thorax, together as wide 

 as long, densely punctate and clothed with brownish hairs. Abdomen as 

 wide as elytra, above densely punctate, sparsely clothed with brownish and 

 yellow hairs ; segments two to six with a double row of small velvety spots. 

 Length 16-20 mm. 



Throughout the State ; scarce. April 15-October 4. Occurs be- 

 neath cover in upland sandy woods. 



8. femoratus Fab., a southern form, 15 mm. in length, has been 

 taken by Dury near Cincinnati and probably occurs sparingly in 

 southern Indiana. 



721 *(2135). Staphylinus tomentosus Grav., Mon. Col. Micr., 1806, 161. 

 Resembles mysticus in form and structure. Color wholly uniform black, 



opaque; thorax, elytra and abdomen sparsely clothed with short, black 

 (rarely brownish) pubescence. Antenna? in both species reaching middle 

 of thorax. Head and thorax in both very densely and regularly punctate, 

 the punctures of head coarser than those of thorax. Length 14-16 mm. 



Throughout the State ; frequent. February 6-October 21. Oc- 

 curs especially along the beaches of lakes, feeding on decaying fish ; 

 also on fungi. 



722 (2136). Staphylinus fossatoe Grav., Mon. Col. Micro., 1806, 164. 

 Elongate, rather robust. Black, subopaque ; antenna? and legs piceous ; 



elytra usually with a large spot of golden pubescence on the outer apical 

 angles. Head, antennae and thorax much as in mysticus, the punctures of 

 head coarser ; the thorax with a narrow, smooth median line on basal half. 

 Elytra as wide as thorax, together as broad as long, densely and roughly 

 punctate. Abdomen slightly narrower than elytra, sparsely pubescent, 

 densely and finely punctate. Length 13-17 mm. 



Putnam and Lawrence counties; rare. August 5-August 21. 

 Occurs in decaying fleshy fungi. 



723 *(2138). Staphylinus ctnnamopterus Grav., Mon. Col. Micr., 1806. 



164. 



Elongate, rather slender. Head, thorax, elytra, tibia?, tarsi, apical mar- 

 gins of abdominal segments and entire last segment, brownish-red; antenna?, 

 under surface, femora and abdomen in great part piceous. Antenna? a lit- 

 tle longer than head, slightly paler toward the tip. Thorax as wide as
