353 (1139). Stenolophus plebejus Dej., Spec. IV, 1828, 424. 



Elongate-oblong. Piceous black, shining ; legs, 

 base of antennae and narrow margin of thorax 

 brownish-yellow. Thorax feebly narrowed behind ; 

 basal impressions small, rounded, each with but 

 two or three punctures; hind angles strongly 

 rounded. Elytra with sutural stria fine, short, 

 oblique, not joining the first dorsal. Length 4.5- 

 5 mm. (Fig. 97.) 



Southern half of State; scarce. March 21- 

 August 17. Closely resembles ochropezus, but Fi §- 97 - x 6/ (Original.) 

 readily distinguished by the comparatively broader thorax and 

 different sutural stria. 



353a ( ). Stenolophus plebejus fuscatus Dej., Sp. IV, 1828, 426. 



A distinct variety of plebejus having the disk of thorax black, with 

 broad, pale margins ; elytra dull red, the tips irregularly fuscous. Basal 

 impressions of thorax deeper and without punctures. Length 5.5 mm. 



lake County; frequent, beneath rubbish along the beach of 

 Lake Michigan. April 29-May 14. 



*354 (1140). Stenolophus conjunctly Say, Trans. Amer. Phil. Soc, II, 

 1823, 90 ; ibid. II, 504. 

 Oblong. Piceous, shining; legs and base of antennae reddish-brown. 

 Thorax broader than long, the sides broadly rounded into base, so that hind 

 angles are wanting. Elytral stria? fine ; intervals flat. Length 3.5-4.5 mm. 



Throughout the State; common, especially in sandy localities. 

 Hibernates. Abundant on the wing in early spring and at electric 

 lights. February 6-December 3. The smaller size and uniform 

 color cf thorax readily distinguish this species. 



*355 (1145). Stenolophus ocheopezus Say, Trans. Amer. Phil. Soc. II, 



1823, 54; ibid. II, 478. 



Elongate-oblong, rather slender. Black or pice- 

 ous, the elytra often iridescent ; legs and base 

 of antennae pale. Thorax scarcely wider than 

 long, convex ; hind angles obtuse, rounded ; basal 

 impressions broad, shallow, sparsely but distinct- 

 ly punctured. Elytral striae rather deep, es- 

 pecially toward the tip ; intervals flat. Length 

 5.5-0 mm. (Fig. 98.) 



Throughout the State; common. Hiber-
