i 



the incised line short and deep, the outer oblique, linear, distinct 

 and attaining the basal margin; elytra fully one-half longer than 

 wide, ogivally rounded in about apical third, slightly wider than the 

 prothorax; striae fine, not deep, minutely, closely punctulate, the 

 inner feebly impressed, the scutellar long, not free; intervals flat, 

 almost so internally. Length (9) 6.8 mm.; width 2.8 mm. Lake 

 Superior (Marquette), John D. Sherman, Jr shermani n. sp. 



Legs rufous, the tarsi alone piceous; prothorax of the usual form, widest 

 at base. Body notably elongate, rather convex, black, without evi- 

 dent metallic lustre, polished, the elytra (9 ) very slightly less shin- 

 ing: epipleura pallescent; metasternum and side-pieces variably 

 punctate; head well developed, fully three-fifths as wide as the pro- 

 thorax, the eyes large and prominent; antennae rather long and slen- 

 der; prothorax two-fifths wider than long, the sides broadly arcuate 

 and anteriorly converging, nearly straight and subparallel behind 

 the middle; apex feebly sinuate, with well marked and but slightly 

 blunt angles; basal angles right, the puncture symmetrically placed; 

 impressions variably evident; foveal region with fine scattered punc- 

 tures, sometimes virtually impunctate, the foveae very feeble, the 

 incised discal line of the inner evident, the outer obsolete; elytra 

 one-half longer than wide, the sides arcuate, the apex gradually 

 ogival, at the middle, distinctly (9 ), or slightly (cf ), wider than the 

 prothorax; subapical sinus pronounced; striae not very fine, groove- 

 like, very finely, closely punctulate as a rule, the scutellar moder- 

 ately long, broadly free at tip; intervals nearly flat in both sexes; 

 seventh stria very feeble. Male distinctly smaller than the female. 

 Length (cf 9 ) 6.3-7.8 mm.; width 2.3-3.0 mm. California (Sta. 

 Cruz to Humboldt Co.) longula Lee. 



Legs pale rufous throughout, the tarsi not darker, except at the extreme 

 tips of the joints; prothorax of the usual form, widest at base 5 



5 Body oblong-suboval, convex, highly polished throughout in both 

 sexes, aeneous or in part viridi-aeneous above, black beneath; head 

 small, barely half as wide as the prothorax, with large and rather 

 prominent eyes; antennae long, extending well behind the thoracic 

 base in both sexes; prothorax one-half to three-fifths wider than long, 

 with the sides strongly arcuate and converging anteriorly, becoming 

 gradually parallel basally; apex barely two-thirds as wide as the 

 base, rather feebly sinuate and with moderately blunt angles; basal 

 angles right, slightly blunt, the puncture coarse, distant from base 

 and side, nearer the former; base distinctly sinuate at each side; 

 surface somewhat strigose transversely toward the fine median stria, 

 the posterior impression often evident; foveal region with scattered 

 punctures; inner fovea deep, lineiform, distant from the base, the 

 outer small, rounded, subobsolete and discal; elytra very nearly 

 one-half longer than wide, regularly ogival in apical two-fifths, equal 

 in width to the prothorax; striae rather strong, groove-like, generally 

 impunctate, the scutellar very short, free; intervals evidently con- 

 vex; anterior tarsi (cf ) more strongly dilated than in pallipes. 

 Length (c? 9 ) 5.8-6.5 mm.; width 2.45-2.7 mm. New York. Five 

 examples. [Amara indistincta Hald.] angustata Say
