1592 (4941). Telephoeus pusillus Lee, Proc. Phil. Acad. Nat. Sci., V, 



1851, 343. 



Elongate, slender. Black or piceous ; front of head, sides of thorax and 

 legs yellow; elytra with narrow sutural and marginal lines pale yellow. 

 Thorax not wider than long, sides nearly straight, not strongly reflexed. 

 Elytra sparsely clothed with semi-erect grayish hairs, the marginal and 

 sutural pale stripes much narrower than in scitulus. Length 4-6 mm. 



Throughout the State; common. May 12-July 5. Very close 

 to scitulus and probably merges into that species. 



T. rotundicollis Say, yellow, elytra and ventral segments often 

 piceous, is recorded from Illinois and Lake Superior.

V, 1851, 341. 



Elongate, rather slender. Black, shining; mouth and thorax yellow, 

 the latter with a broad, black dorsal stripe which, in some specimens, is 

 wider along the basal and apical margins. Antennas of male two-thirds as 

 long as body, subserrate; those of female half as long as body. Thorax
