HARPALIN^; 79 



sculpture is much coarser, denser and more rugose throughout; 

 elytra relatively much shorter, three-fifths longer than wide, parallel, 

 broadly rounded at the sides, very obtuse at tip, the sinus very feeble 

 though evident; surface (cf) very shining, the intervals strongly 

 convex suturad, the two outer rather closely, the next one more 

 sparsely, suffusedly punctate, the next two with a few sparse punc- 

 tures, more evident basally, or ( 9 ) strongly, closely, very uniformly 

 punctured throughout, more strongly so than in vagans; tarsi nearly 

 similar in structure. Length (cf 9 ) 16.5-17.0 mm.; width 5.9-6.2 

 mm. Iowa (Keokuk) and Missouri (St Louis). Three examples. 



actiosus n. sp. 



Body larger and more convex than in vagans and deeper black in color, 

 much more slender and smaller than in actiosus, deep black, the legs, 

 trophi and antennae pale testaceous; head rather large, fully two- 

 thirds as wide as the prothorax; mandibles black throughout; 

 prothorax a third wider than long, not so transverse as in vagans 

 but otherwise almost similar, slightly more convex, with the median 

 stria finer; elytra (9) more elongate, fully two-thirds longer than 

 wide, otherwise nearly similar, except that the intervals are less 

 flat and differing from the female of both the preceding species, 

 where the small close-set punctures attain the suture without change 

 of character or density, in having the close-set punctures end 

 abruptly at the first stria, the sutural interval with scarcely any 

 punctures, a few being visible basally. Male slightly stouter than 

 in vagans, almost similarly punctured. Length (cf 9 ) 12.0-16.0 

 mm.; width 4.4-5.5 mm. Pennsylvania and Long Island. Three 

 examples haldemani n. sp. 



4 Punctuation toward the basal thoracic angles fine, sometimes with 

 larger punctures intermingled, the surface there not so abruptly or 

 so strongly flattened 5 



Punctuation toward the angles decidedly coarse, the surface abruptly 

 and more exactly flat 1 1 



5 Elytra not punctured on the flanks in either sex; body smaller in size; 

 head moderate 6 



Elytra with suffused punctulation near the sides in both sexes, but so 

 minute as only to be seen when carefully observed; body large; 

 head notably large 7 



Elytra with suffused punctures near the sides, which are strong and easily 

 observed; head large 10 



6 Form elongate-suboval, rather strongly convex, deep black, shining, 

 a little less so (9 ), where the body is somewhat stouter; legs, trophi 

 and antennae testaceous; eyes prominent, the frontal foveae small 

 as usual; antennae slender, barely attaining the thoracic base (9), 

 a little longer (cf 1 ); prothorax two-fifths wider than long, the sides 

 parallel and broadly, subevenly rounded, the angles slightly obtuse 

 and blunt, the apex sinuate, narrower than the base, which is trans- 

 verse and margined as usual; surface steeply declivous at the sides 

 to the coarsely reflexed and punctured margin, which is lost in the 

 general flattening at about basal third, the acute bead continuous 

 throughout as usual; foveae very shallow and vague; elytra three-
