HARPALIN.E 287 



large and very prominent eyes. Body narrow, elongate, subparallel, 

 convex, shining, piceous-black, the prothorax slightly paler, wholly 

 pale or only toward the edges in the more mature forms; under 

 surface of the hind body blackish, the epipleura and legs pale; head 

 smooth, not as long as wide; antennae blackish, the two basal joints 

 paler, barely longer than the head and prothorax, the joints very 

 short in form; prothorax two-fifths wider than long, widest near 

 apical third, the sides strongly rounded anteriorly, oblique and nearly 

 straight in about basal half; apex sinuato-truncate, evidently wider 

 than the base, which is arcuate, with the angles broadly rounded; 

 surface finely reflexed at the sides, with a rather strong entire median 

 stria, the foveae large, indefinite, feeble and with numerous rather 

 coarse sparse punctures, many of the latter are also scattered along 

 the course of the anterior obsolete transverse impression; elytra 

 nearly one-half longer than wide, not quite a fourth wider than the 

 prothorax, parallel, with feebly arcuate sides and circularly rounded 

 apex, the sinus very feeble but evident; striae impressed, the intervals 

 rather convex; discal puncture near apical third; hind tarsi two-thirds 

 as long as the tibiae, which are relatively short. Length (9) 3.0- 

 3.7 mm.; width 1.0-1.2 mm. New York and Virginia to Louisiana 

 and Texas. [Acupalpus indistinctus Dej.] indistinctus Dej. 



Head much narrower than the prothorax, the eyes always prominent 

 though less developed than in the preceding species 2 



2 Head pale in color, concolorous. Body and legs throughout pale 

 testaceous, the elytra not clouded; head three-fourths as wide as 

 the prothorax; antennae blackish to paler, the two basal joints always 

 pale; prothorax as in the preceding in every detail, except that the 

 sides are more evenly rounded, not becoming straight basally; elytra 

 shorter and relatively broader, two-fifths longer than wide and nearly 

 a third wider than the prothorax, parallel, the sides feebly arcuate; 

 apex subcircularly very obtuse, the sinus obsolete; striae impressed, 

 the scutellar very short to wholly obsolete; intervals rather feebly 

 convex; discal puncture near apical fourth; hind tarsi very short, 

 three-fifths as long as the tibiae, the fifth joint long as usual. Length 

 (cf 9 ) 2.4-2.7 mm.; width 0.8-0.9 mm. Rhode Island to Texas. 

 Abundant. [Acupalpus testaceus Dej.; Agonoderus micros Lee.]. 



testaceus Dej. 



Head black or blackish in color 3 



3 Form subparallel, convex, shining, testaceous, the head black; elytra 

 black almost throughout, sometimes more or less broadly pallescent 

 laterally; under surface of the hind body black to red-brown; epi- 

 pleura and legs pale; head and antennae as in testaceus, except in color; 

 prothorax nearly similar but less transverse, only about a third wider 

 than long, widest before the middle but with the sides subevenly 

 rounded, converging and less arcuate basally; apex sinuato-truncate 

 and a little wider than the base; surface as in indistinctus throughout; 

 elytra nearly one-half longer than wide, a fourth wider than the 

 prothorax, parallel; apex obtusely, subcircularly rounded; the sinus 

 obsolete; striae rather fine and feebly impressed, the scutellar ex- 

 tremely short; intervals very feebly convex; discal puncture near
