2368 ( 7615). Mycetociiares iialdemani Lee, New Sp N Am Col I 

 1866, 140. 



Oblong, subparallel, convex. Blackish-piceous, strongly shining; elytra 

 each with a large oblique reddish spot extending from near the suture to 

 humerus; tibiae, tarsi and basal portion of antenna reddish-yellow Eyes 

 small, separated by four times their width. Thorax nearly twice as wide 

 as long, convex, sides strongly rounded; surface, as well as that of elytra 

 very finely and sparsely punctured. Elytra parallel to basal third, thence 

 rather acutely narrowed to apex. Length 4-4.5 mm. 



Marion, Vermillion. Dubois and Perry counties ; rare. May 23- 

 June 11. Our smallest form, easily recognized by its almost smooth 

 polished surface. 



2369 (7616). Mycetociiares fraterna Say, Journ. Phil. Acad Nat Sci 

 III, 1823, 270 ; ibid. II, 159. 

 Elongate-oblong, parallel, subdepressed. Piceous-black, shining; an- 

 tennae, palpi and tarsi reddish-brown; elytra with an oblique, pale yellowish 

 spot on basal third ; pubescence fine, short and sparse. Eyes separated by 

 a little more than twice their width. Thorax twice as wide as long, as 

 wide or slightly wider than base of elytra, sides broadly curved; surface 

 rather finely and sparsely punctate, with a broad, distinct impression on 

 middle near base, and a more feeble one each side. Elytra rather finely 

 and unevenly punctured, witb one or two vague strife near the suture

2370 (10,679). Mycetociiares megalops Casey, Ann. N Y Acad Sci VI 

 1891, 129. 



Elongate-oblong, subparallel, subconvex. Black, shining; under sur- 

 face piceous ; legs and antennae dark reddish-brown, the latter paler at 

 base. Eyes as described in key. Thorax not quite twice as wide as long- 

 sides nearly straight and subparallel on basal third, thence broadly rounded 

 to apex ; disk finely and sparsely punctate, the impressions more feeble than 

 m fratcrna. Elytra equal in width to thorax, parallel to apical third, thence 

 obtusely rounded to tips; surface sparsely and rather roughly punctate, the 

 striae evident on inner half, obsolete or nearly so on sides. Length 4.5 mm. 



Lake, Kosciusko and Marion counties; rare. May 22-June 19. 

 One taken from an old coat in the back yard of a city residence by 

 P. Baker ; also bred from willow. The larger eyes and less strongly 

 rounded sides, of thorax distinguish this from fraterna, which it 

 otherwise very much resembles.
