 Short, broad, subparallel. Blackish-piceous, shining; elytra often more 



or less brownish ; antennae and legs pale yellow. Thorax twice as wide as 

 long, slightly wider than head, sides curved, surface minutely and sparsely 

 punctate. Elytra a little wider and longer than thorax, sparsely pubescent; 

 minutely, roughly and sparsely punctate. Length 1-1.5 mm. 



Marion, Monroe and Posey comities; frequent locally. June 2- 

 October 31. Occurs in leathery fungi on sides of oak and beech 

 stumps. 



636 (- ). GYROPHrENA lobata Casey, Trans. Acad. Sci. St. Louis, XVI, 



190G, 293. 



Rather stout, spindle-shaped. Brownish-yellow, shining; head black, 

 outer apical angle of elytra, disk of thorax and fourth dorsal segment of ab- 

 domen more or less fuscous. Antenna? reaching base of elytra, joints 5-10 

 brownish, slightly wider than long. Thorax much wider than head, two- 

 thirds wider than long, sides broadly rounded into base ; disk smooth with

 strong. Elytra a fourth wider and one-half longer than thorax, minutely 

 and sparsely punctate. Length 2,2 mm. 



Marion County ; rare. May 22. Taken by sweeping. Described

637 (2077). Gyroph^ena vinuia Erichs., Gen. Sp. Staph., 1S40, 186. 

 Rather stout, subparallel. Pale reddish-yellow; head, apical third of 



elytra, except at suture, and fourth and fifth dorsal segments of abdomen 

 black or piceous. Thorax not quite twice as wide as long, parallel and 

 rounded on the sides; surface very sparsely and obsoletely punctate with 

 two larger punctures behind the middle. Elytra about one-fifth wider and 

 one-half longer than thorax, finely and sparsely punctate. Length 1.5- 

 2.5 mm. 



Southern half of State; frequent. March 20-September 25. 

 Occurs on fleshy fungi. 



638 (2078). Gyrophjena dissimius Erichs., Gen. Sp. Staph., 1840, 186. 

 Form of vinuia. Pale dull yellow; head, apical angles of elytra and 



apical half of abdomen blackish ; antennae and legs yellow. Thorax wider 

 than head, nearly twice as wide as long, otherwise as in vinuia. Elytra 

 with the humeri more narrowly exposed than in that species. Length 1.5- 

 2.3 mm. 



Southern half of State ; frequent, May 13-September 25. 



Placusa Er. 1837. (Gr., "plate,") 



Antennae sunt, head rather small; thorax broad, strongly trans- 

 verse ; elytra large, abdomen subparallel. 



Xo member of the genus has as yet been recorded from Indiana, 

 but its occurrence in the State is very probable.
