foveae near two-fifths and three-fourths. Length (cf 9 ) 4.7-5.4 

 mm.; width 1.8-2.1 mm. Indiana and Iowa. Abundant. 



chalceum Dej. 



Form rather broader; size larger, nearly as polished, black, the anterior 

 parts with greenish lustre, the elytra aeneous; head nearly similar, 

 the eyes not quite so large; antennae longer and mqre slender, simi- 

 larly colored, the medial joints more than three times as long as 

 wide; prothorax two-fifths to one-half wider than long, in outline 

 nearly as in chalceum but less convex, with less strongly rounded 

 sides and deeper transverse impressions, broader at base, the latter 

 not very obviously narrower than the apex; foveae linear, longer and 

 more oblique, the carina wanting; sides well reflexed, becoming ex- 

 tremely finely so at apex; elytra rather more than one-half longer 

 than wide, three-fifths wider than the prothorax, parallel, with 

 feebly arcuate sides, not quite so rapidly rounding at base as in 

 chalceum, the apex more gradually obtusely ogival; impressed striae 

 still conspicuous at apex; the strong and close-set punctures are, 

 however, obsolete at about apical third or fourth; foveae similar. 

 Length (of 1 9 ) 5.7-6.0 mm.; width 2.1-2.35 mm. Texas. Two ex- 

 amples integrum n. sp. 



63 Elytra very gradually ogival behind in almost apical half. Body 

 larger in size, moderately convex, shining, piceous-black, with green- 

 ish lustre anteriorly, the elytra very pale and uniform testaceous, 

 with a triangular fuscous area at base; under surface nearly black, 

 the legs rufous; head rather large, four-fifths as wide as the prothorax 

 and as wide as an elytron, the eyes moderately prominent; antennae 

 long and slender, testaceous, the medial joints three times as long 

 as wide; prothorax relatively large, two-fifths wider than long, much 

 narrower at base than at apex, the sides subevenly and strongly 

 rounded, rather abruptly straight and subparallel in about basal 

 sixth, the angles right; surface depressed at base, the anterior im- 

 pression distinct, the stria fine, not entire; foveae rather small, deep, 

 oval, the carina distinct; margins very finely reflexed; elytra slightly 

 more than one-half longer than wide, only two-fifths wider than the 

 prothorax, wider behind the middle than at base, the humeri rapidly 

 rounding; striae very fine, entire, barely at all impressed, the punc- 

 tures very fine and rather widely separated; foveae small, near 

 two and four fifths. Length (cf) 5.2 mm.; width 1.9 mm. New 

 Mexico (somewhere between Fort Wingate and Jemez Springs), 

 Woodgate sejunctum n. sp. 



Elytra more rapidly rounding behind, parallel; body much smaller in 

 size 64 



64 Sides of the prothorax rather abruptly straight and parallel in about 

 basal sixth 65 



Sides gradually though distinctly sinuate basally, becoming parallel only 

 at the angles 66 



65 Form moderately slender, rather more convex, shining, black, the 

 anterior parts with greenish lustre, the elytra testaceous, with the 

 apical margin slightly clouded and with a common fuscous spot just 

 behind the middle, the spot laterally prolonged and attenuated; legs
