half longer than wide; tarsi long and slender. Length (9 ) 7-2 mm.; 

 width 2.8 mm. A single specimen without label from the Levette 



collection. New York, — LeConte vagans Lee. 



3 — Elytral striae without vestige of punctulation. Form elongate- 

 suboval, rather convex, shining, black, the head and prothorax with 

 strong green lustre, the elytra subcupreous; epipleura black to 

 piceous; legs testaceous, the knees and tarsi blackish; head elon- 

 gate, two-thirds as wide as the prothorax, with well developed but 

 rather feebly convex eyes; antennae black, with the first joint 

 piceous, three-fifths as long as the body, the third joint not quite as 

 long as the fourth; palpi slender, piceous-black; prothorax about 

 as long as wide, the parallel sides evenly, circularly rounded from 

 apex to base, finely reflexed, a little more so at base, where they 

 form the outer wall of the foveae ; apex rather deeply sinuate; basal 

 angles broadly rounded, the apical prominent, only finely blunt 

 at tip; surface with transverse rugulae, the impressions obsolete, 

 the stria entire; fovese rather deep, nearly smooth, traceable almost 

 to the middle; elytra three-fifths longer than wide, evidently less 

 than twice as wide as the prothorax, the parallel sides broadly 

 arcuate, gradually more so basally; apex gradually rounding, the 

 sinus very feeble; striae very fine but deep, abruptly grooved, com- 

 pletely impunctate, the scutellar notably long, the ninth half as 

 far from the edge as from the eighth; intervals flat; dorsal punctures 

 five; anterior male tarsi evidently but very narrowly dilated. 

 Length (cf 9) 7.0-8.3 mm.; width 2.75-3.1 mm. Indiana to 



Iowa (Keokuk). Not uncommon nutans Say 



Elytral striae minutely and feebly punctulate 4 



Elytral striae with very distinct punctures, though always much smaller 

 than in the ferreum group, the striae also finer; dorsal punctures 



five 9 



4 — Prothorax evidently wider than long 5 



Prothorax about as long as wide 6 



5 — Form rather stout, convex, shining, black, the anterior parts very 

 feebly greenish; under surface black, the epipleura and legs pale, 

 the femora feebly clouded distally; head elongate, three-fourths as 

 wide as the prothorax, the eyes well developed but only feebly 

 prominent; antennae black, with piceous basal joint and with the 

 third scarcely as long as the fourth, long, slender, fully two-thirds 

 as long as the body; prothorax a fifth wider than long, the sides 

 evenly rounded and finely reflexed, more converging and reflexed 

 basally, forming the outer wall of the foveae, which are deep, with a 

 few small punctures, traceable anteriorly to the middle of the 

 length; base not quite as wide as the feebly sinuate apex; basal 

 angles obtuse, rounded at tip, the apical rather sharp; impressions 

 feebly traceable, the stria entire; elytra oblong-oval, slightly less 

 than one-half longer than wide, four-fifths wider than the prothorax, 

 rather obtuse at tip, with feeble sinus; striae fine, grooved, a little 

 coarser at tip, with very fine and close-set punctures, obsolete 

 posteriad, the scutellar long, punctulate; intervals virtually flat, 

 the third with four punctures; met-episterna one-half longer than
