138 CASEY 



ently punctate, trisulcate and marked with four smooth elevated vittae; 

 elytra densely punctate, the sutural stria distinct, the suture elevated; 

 alternate intervals with elongate smooth elevated spaces, the sides 

 posteriorly oblique and gradually converging [becoming sinuate], the 

 tips slightly prolonged and bidentate; under surface coppery, densely 

 and coarsely punctured at the sides, nearly smooth or sparsely punc- 

 tured at the middle; prosternum deeply, the first ventral moderately, 

 sulcate, the metasternum almost flat; male with the last ventral tri- 

 dentate, the medial tooth short and broadly truncate, the middle tibiae 

 straight and unmodified; female with the medial tooth of the apical 

 sinus acute. Length 15.0 mm. Alabama to Pennsylvania. [ = />z/^io- 

 nata Lap. -Gory nee Germ.] lepida Lee. 



Form moderately elongate, much smaller, convex, shining, somewhat ob- 

 scure coppery above, brighter cupreous beneath; head rather small, 

 very coarsely but not so densely punctato-rugose, with large irregular 

 central callous spaces; eyes rather small but prominent; prothorax 

 short, three-fourths wider than long, the sides feebly arcuate and mod- 

 erately converging before the middle, subparallel and feebly sinuate 

 basally, the apex feebly sinuate; surface with a densely punctured 

 median channel, with the ridges broad, nearly flat and sparsely punc- 

 tate, thence to the sides coarsely, confluently punctate, with a more or less 

 incomplete and narrower callous vitta, and some smaller callous spaces 

 still nearer the sides; elytra barely wider than the prothorax, much 

 more than twice as long as wide, the sides gradually rounding and con- 

 verging from slightly behind the middle, becoming broadly sinuate, the 

 tips greatly produced as in the next group, deeply sinuate and bispicu- 

 lose, the surface uneven, with series of small punctures suturally, 

 rather coarsely, densely and unevenly punctate laterally, the alternate 

 intervals with strongly elevated but very irregular, elongate and smooth 

 greenish-black spaces, the finely punctured areolae rather distinct; 

 under surface axially grooved, more strongly in the male, in which 

 the middle tibiae are unmodified, the median lobe of the apical emargi- 

 nation moderately broad, truncate, the medial tooth of the female 

 sinus long and slender. Length 11. 0-12.0 mm.; width 3.6-4.0 mm.

In regard to lepida Lee, which I have been unable to examine, it 

 is stated by Crotch (1. c. p. 87) that the prothorax is longer than wide, 

 but, though perhaps unusually elongate, it certainly cannot even be 

 so long as wide, as indeed definitely so stated by LeConte. 



Group III — Type divaricata Say. 



In this group the elytra are more prolonged at apex than in any 

 other, this character giving the species a habitus which is altogether 

 distinctive. It is the largest group of the genus and comprises a wide
