1192 (3614). Sapeinus sphjseoides Lee, Bost. Jour. Nat Hist, V, 1845, 78. 



pi. VI, fig. 5. 



Rounded-oval. Bronzed or cupreous, shining. Thorax sparsely punc- 

 tured in front and at the sides; basal margin more coarsely punctured, disk 

 smooth. Elytra finely punctured on apical third in space between the 

 fourth dorsal and sutural; external subhumeral rather long, humeral finely 

 impressed, not uniting with the internal subhumeral; first dorsal stria ex- 

 tending four-fifths to apex and sinuate at tip; second, third and fourth 

 gradually shorter, the fourth arching to join the sutural, which is entire. 

 Front tibire coarsely denticulate, the apical three teeth longer than the 

 others. Length 2.5-3.5 mm. 



Beneath rubbish on beach of Lake Michigan, near Millers, Lake 

 County ; scarce. May 12-June 9. 



1193 ( ). Sapeinus lakensis sp. nov. 



Broadly oblong-oval, convex. Black, strongly shining. Head distinctly 

 margined, nearly smooth, rugose in front. Thorax with the disk sparsely 

 and evenly punctured, the sides and apex with strigose punctures. Elytra 

 very finely and sparsely but distinctly punctured near the suture on apical 

 third, elsewhere wholly smooth, polished ; external subhumeral short, indis- 

 tinct ; humeral finely impressed, not joining the internal subhumeral, which 

 is obsolete towards apex ; dorsal striae very fine, the first extending four- 

 fifths to apex, second, third and fourth gradually shorter, the fourth arched 

 at base and joining the sutural, which is entire. Pygidium and propy- 

 gidium finely, densely and evenly punctured. Front tibiae with five or six 

 teeth, the apical three broader and more flattened. Length 4.2 mm. 



Described from a single specimen taken from beneath a log on 

 the beach of Lake Michigan near Millers, Lake County. July 25. 

 It is readily known from sphceroides by its larger size, its polished 

 black hue, by having the entire surface of thorax punctured, and 

 by the much smaller and more finely punctured space of elytra,

 Resembles spliwroides but the punctured space of thorax is larger and 



more distinctly strigose on sides and in front; that of elytra is also larger 

 with coarser punctures and the sutural stria reaches only two-thirds to apex. 

 Length 3-3.5 mm. 



Beneath rubbish and dead fish on beach of Lake Michigan near 

 Pine and Millers, Lake County ; scarce. May 14-July 27. Re- 

 corded heretofore only from Nebraska, 



1195 (3617). Sapeinus feateenus Say, Journ. Phil. Acad. Nat. Sci., V. 



1825, 40; ibid. II, 266. 



Broadly oval, convex. Black tinged with bronze, subopaque. Thorax 

 rather densely punctured, the punctures on sides somewhat strigose, a broad 

 triangular space on disk nearly smooth. Elytra everywhere densely punc- 

 tured except on a well defined, shining scutellar space which is limited at
