It extends over the greater part of the region east of the Rocky 

 Mountains, being known to me from Maine. New York, New Jersey, 

 Pennsylvania, Delaware, South Carolina, Ohio, Michigan, Kentucky, 

 Illinois, Iowa, Missouri, Louisiana and Texas. 



17. B. dilatatuiii Lee. — Form broad, dilated moderately depressed ; color 

 bronzed, shiuiuo;. Head slightly narrower than the thorax at apex ; palpi rufons, 

 darker at tip ; anteunie about one-half as long as the body, piceous, the first joint 

 rufous. Prothorax moi-e than one-half wider than long, narrower at base than 

 apex, slightly rugose at base ; apex nearly truncate, median line distinct, extend- 

 ing between the transverse impressions, which are distinct; ba-sal impressions 

 moderately deep ; sides with the margin narrowly reflexed, strongly arcuate in 

 front, distinctly sinuate beliiud ; hind angles obtuse, but not rounded. Elytra 

 about one-half wider than the thorax, oblong-oval, moderately deeply striate, more 

 finely at tip ; strife distinctly punctate to behind the middle, the third with the 

 first dorsal puncture slightly in front of the middle, the second about one-fourth 

 from apex ; intervals flat. Beneath more or less tinged with green, shining. 

 Legs dark rufous. Length .26-.29 inch ; 6.5-7.25 mm. 



So far as can be judged from the small amount of material exam- 

 ined, this sjDecies seems distinct by the above characters. 



But two specimens are known to me, LeConte's type from Colum- 

 bia, Pa., and one in Dr. Horn's cabinet from the Indian Territory. 



18. B. honestiiiii Say. — Form rather elongate, feebly convex ; color aeneous, 

 usually more or less coppery, more rarely bluish or greenish, shining. Head as 

 wide as the thorax at apex ; palfii piceous, more or less rufous at base ; antennae 

 about one-half the length of the body, piceous, the first joint more or less rufous. 

 Prothorax less than one-half wider than long, scarcely narrower at base than apex, 

 rugose at base ; apex slightly emarginate ; median line deep, abbreviated before and 

 behind ; transverse impressions distinct : b.asal impressions moderately deep ; sides 

 with the margin narrowly reflexed, slightly arcuate in front, feebly sinuate be- 

 hind ; hind angles subrectangular. Elytra about one-half wider than the thorax, 

 oblong-ovate, moderately deeply striate, less deeply towards the apex ; striae dis- 

 tinctly punctate, the punctures becoming obsolete at tip ; third stria with the first 

 dorsal puncture slightly in front of the middle, the second about one-fourth from 

 apex ; intervals slightly convex. Beneath black, slightly tinged with green, 

 shining. Legs aeneo-piceous, the femora at base and sometimes the tibiae more or 

 less rufons. Length .23-.27 inch ; 5.75-6.75 mm. 



More convex than dilatatum, than which it is also more slender. 

 The thorax is proportionally less wide as compared with its length 

 and less narrowed behind, with the hind angles subrectangular. It 

 is most nearl}^ related to the next species, but the form is le.ss convex 

 and the thorax scarcely narrower at base than apex, with the sides 

 less arcuate in front and less sinuate behind. The elytra are less 

 deeply striate, with the striae less deeply punctured. 



The name honestum Say has several years priority over that of
