41)!) 



Common throughout the State; hibernates. January 7— October 

 6. Frequent on leaves of skunk cabbage, sedges, Peltandra, etc., in 

 moist places in early spring. 



95G (2004). Phalacrus pumilio Lee, Proe. Phil. Acad. Nat Sci.. VIII, 

 1S56. 16. 



Resembles politus but smaller and more narrowly oval. Third joint of 

 antenna? notably shorter than fourth and fifth together. Prosternal process 

 much narrower, not over one-third as wide as the metasternal. Elytral 

 punctures more distant and less distinct. Length 1.4 mm. 



Lake, Fountain and Lawrence counties; scarce. May 17- 

 July 1. 



II. Olibrus Eriehs. 1845. (Gr., ''slippery.") 



The mode of antennal insertion and the size of scutellum distin- 

 guish this genus from Phalacrus. In our two species the elytra are 

 of one color and have two discal striae on each, one near the suture 

 extending to basal third and joining the suture at apex, the second 

 closely parallel and a little shorter. 



057 (.3000). Olibrus semistriatus Lee, Proc. Phil. Acad. Nat. Sci., VIII, 



1856. 16. 



Oblong-ovate, strongly convex. Above dark chestnut-brown, highly pol- 

 ished ; beneath pale reddish-yellow, antennae and legs of the same hue. 

 Thorax very sparsely and feebly punctate. Elytra with two discal striae 

 near the suture and with feebly impressed lines along the very fine rows of 

 punctures. Length 1.8-2.2 mm. 



Southern half of State, frequent; less so in the northern coun- 

 ties. March 27— October 1. Occurs on flowers of Eupatorium and 

 Solidago (thoroughwort and goldenrodh Taken in spring by sift- 

 ing. 



058 (3002). Olibrus pallipes Say, Journ. Phil. Acad. Xat. Sci.. IV, 1825, 



00 ; ibid. II. 230. 



Elliptical, very convex, highly polished. Above dark piceous-brown, the 

 head and thorax a little darker than elytra ; antennae and under parts pale 

 brownish-yellow. Thorax with minute obsolete punctures on each side. 

 Elytra with discal stria? and rows of fine punctures as in semistridtiis but 

 without the accompanying impressed lines along the row of punctures. 

 Length 2.5-2.8 mm. 



Lake and Knox counties; scarce. July 30- August 31. Longer 

 and more narrowly oval than the preceding. 



III. Acylomus Sharp. 1888. (Gr.. "an acorn.") 



Small oval, more or less convex beetles, having the second joint 

 of hind tarsi very much elongate and in the male spongy pubescent, 

 as in the males of the genus Anisodactylus of the family Carabida\
