NORTH AMERICAN COLEOPTERA. 211 



OcL-ur.s tVuin South ('aroliiia to Texas. [ have seen one specimen 

 from Canada, which [ doubtfully place with this species. 



P. versiitus n. sp. — Piceous, tliorax and elytra brownish testaceous; legs 

 paler: aiitennte a little shorter than the head and thorax, brownish, two basal 

 joints paler, joints 4-10 not longer than wide, the outer ones quite transverse ; head 

 black, sub-quadrate, not narrowed behind the eyes, hind angles not punctulate ; 

 tliorax not wider nor longer than the head, sub-quadrate, as wide as long, not nar- 

 rowed in front, dorsal punctures three, moderate in size, equidistant; elytra a 

 little wider and longer than the thorax, longer than wide conjointly, punctures 

 moderate in size, closely but not densely placed; surface moderately shining, 

 sparsely pubescent; abdomen a little more finely and sparsely punctured than the 

 elytra; beneath more closely punctured than above, the basal segments especially 

 densely. Length .22 inch; 5.5 mm. 



Male. — Anterior tarsi filiform : last ventral segment truncate, with a scarcely 

 perceptible emarginatioii. 



Femn/e. — Tarsi filiform ; last ventral entire. 



This species is very closely relied to the preceding. At first sight 

 ttujuietu.s is rather depressed, versutus more cylindrical. The former 

 has a sparsely punctured abdomen, the latter densely at base beneath. 

 On actual comparison the form of the last ventral of the male differs in 

 the two species, but in a manner almost impossible to describe. 



The elytra are usually uniform in color, brownish testaceous ; some 

 specimens, however, are clouded, leaving the suture and side margin of 

 that color. 



Occurs in ('aiii'oriiia. 



P. veiltralis Grav.— Form moderately elongate, oiceous or brownish; elytra 

 slightfy bronzed ; antennje as long as the head and thorax, piceous, two basal joints 

 pale, joints 4-10 as wide as long; head oval, slightly narrowed behind the eyes, 

 hind angles not punctulate ; thorax a little wider than the head, sub-quadrate, not 

 narrowed in front, dorsal punctures four, large and deep, the first three closely 

 placed, the fourth more distant; elytra a little wider than the thorax, convex, 

 cimjointly nearly square, rather coarsely and moderately closely punctate, sparsely 

 I)ubescent; abdomen sparsely punctured, the punctures finer than those of the 

 elytra; beneath more coarsely punctured than above. Length .20 inch; 5 mm. 



Male. — Tarsi filifoiin ; last ventral with an extremely feeble emargination, and 

 a very slight triangular impression. 



J^e ma /e.— Tarsi filiform; last ventral entire. 



This species is easily known by its rather square (juadripunctate thorax. 

 It is difficult to separate the females from some of the smaller species of 

 series B. 



Occurs in Europe, extending to Siberia and Africa. In our fauna it 

 occurs in Michigan, Missouri and Nevada. 



P. distans n. s]). — Black, piceous or brown; elytra slightly bronzed; legs 

 testaceous; antennae entirely piceous, as long as the head and thorax, joints 5-10 

 as broad as long: head oval ; sides nearly straight, hind angles not punctulate;
