646 FAMILY XXVI. NITIDULID/E. 



1243 (3743). Psilopyqa nigeipennis Lee, N. Sp. N. Am. Ool., I, 1863, 64. 

 Form of histrina. Reddish-yellow; elytra alone black, shining. Disk 



of thorax more sparsely and less coarsely punctured than in histrina, with- 

 out coarse punctures near apex. Elytral striae less deep, the punctures 

 smaller; intervals flat. Length i-A.o mm. 



Montgomery County; rare. July 4. Both this and the pre- 

 ceding were taken by Earl Grimes of Russellville, Indiana, from 

 the same stink-horn fungus. As stated by Horn, this may prove 

 to be but a variety of histrina. Both resemble species of Hister 

 very closely and are usually placed with that genus by beginners. 



XVI. Amphicrossus Erichs. 1843. (Gr., "on both sides -i- 



fringe.") 



Oval, brownish or piceous species having the labrum bilobed; 

 front tarsi distinctly dilated, hind ones simple ; claws not toothed. 

 One species occurs in the State. 



1244 (3744). Amphickossus ciliatus Oliv., Bncyc. Meth., VIII, 210. 

 Broadly oval. Piceous, subopaque, pubescent; thorax with margins 



and a spot in front of scutellum paler ; elytra each with three paler spots 

 at base and sometimes a fourth near apex; legs yellowish. Thorax more 

 than twice as wide as long, narrowed in front, apex deeply emarginate; 

 sides feebly curved, hind angles broadly rounded ; surface rather closely 

 punctate. Elytra as long as wide, surface more finely and less densely 

 punctured than thorax. Males with a small tuft of stiff hairs, resembling 

 a spine, near the middle of the suture. Length 8.5-4.5 mm. 



Marion, Putnam and Knox counties; frequent. April 7-Sep- 

 tember 21. Occurs at sap in spring; on flowers of Eupatorium and 

 allied plants in autumn. 



XVII. Pallodes Erichs. 1843. (Gr., "a balUlike.") 



In this genus the prosternum is but slightly prolonged and not 

 dilated at tip ; mandibles bifid ; front and middle tarsi dilated. But 

 one species is known. 



1245 (3747). Pallodes pallidus Beauv., Ins. Afr. et Amer., 1805, 157. 

 Oval, convex. Dull reddish-brown, shining ; elytra somewhat irides- 

 cent. Thorax more than twice as wide as long, much narrowed in front, 

 ajiex emarginate, sides i-iirve<l, bind iingles rectangular; surface sparsely 

 and finely punctate. Scutellum large, sparsely punctate. Elytra longer 

 than wide, each with nine rows of fine punctures; intervals each with a 

 single row of very fine ones. Length .M-4 mm. 



Throughout the State; frequent on fleshy fungi. ]\Iay 2-Sep-
