1 T >2 MEMOIRS ON THE COLEOPTERA 



convex, polished in both sexes, dark testaceous, the elytra black, 

 with the opalescence feebler than in dichrous, the under surface, 

 legs and cephalic appendages testaceous; head fully three-fifths 

 as wide as the prothorax, the eyes well developed and convex, the 

 foveae larger than usual, deeply impressed and sublinear though 

 short; antennae rather long, very slender; prothorax more than one- 

 half wider than long, the sides rounded anteriorly, the apex very 

 feebly sinuate and as wide as the base, which is transverse and 

 minutely beaded; surface only feebly convex, rather broadly reflexed 

 at the sides, the gutter equal as far as basal third, where it disappears 

 on the broadly flattened and strongly punctured latero-basal region, 

 the foveae moderately impressed and punctured, the area of punctures 

 extending to the middle more basally; stria strong, almost entire; 

 marginal puncture before the middle small and very inconspicuous; 

 elytra one-half longer than wide, a third wider than the prothorax, 

 with parallel and rather strongly arcuate sides and ogival apex, the 

 sinus very feeble and almost obsolete; striae fine but rather deeply 

 impressed, the scutellar moderately long, free, the puncture small 

 and at apical third; abdomen not evidently punctured basally; 

 hind tarsi very slender, the basal joint but slightly longer than the 

 next two combined. Length (c? 1 9) 9.0-10.0 mm.; width 3-35-3-7 

 mm. Indiana and Missouri. [Harpahts vulpeculus Say]. 



vulpeculus Say 



Sides of the prothorax arcuate throughout, less so but only feebly con- 

 verging basally, the hind angles obtuse and more or less broadly 

 rounded; prothorax larger than in the preceding 2 



2 Body oblong-oval or subparallel, moderately convex, strongly shining, 

 dark testaceous throughout as in vulpeculus, the elytra black, with 

 stronger opalescence than in that species; head not quite so short, 

 the eyes rather smaller, the foveae very much smaller, punctiform 

 but lying in feeble impressions; antennae rather long, very slender; 

 prothorax not more than two-fifths wider than long, the broadly 

 rounded sides almost even throughout, the apex feebly sinuate, with 

 rather narrowly rounded angles and differing greatly from vulpeculus 

 in being barely more than three-fourths as wide as the base, which is 

 similarly transverse and finely beaded; surface nearly as in the 

 preceding, except that the rather coarse marginal gutter bends 

 inward, broadens, becomes feeble and disappears posteriorly; an- 

 terior transverse impression similarly rather distinct; elytra nearly 

 three-fifths longer than wide, about a fifth wider than the prothorax, 

 the parallel sides more feebly arcuate, the apex rather acutely ogival, 

 with a feeble though evident sinus; striae not very fine and deeply 

 impressed, the scutellar very long, parallel and free, the intervals 

 strongly convex, highly polished, very strongly opalescent and per- 

 fectly similar in the sexes, the puncture small but deep and much less 

 posterior, being at about three-fifths; hind tarsi very slender, the 

 basal joint a little longer than the next two combined. Length (cf 9 ) 

 10.0-10.7 mm.; width 3.8-4.1 mm. New York (Long Island) to 

 Missouri. Ten examples. [Harpalus dichrous Dej.]. . dichrous Dej.
