6. L. POLITA. — Head and thorax glabrous, brassy, green, 

 polished ; elytra pale olivaceous ; feet rufous, trochanters and 

 four anterior tibia bluish. 



Inhabits Georgia. 



Body above glabrous, punctured ; beneath hairy ; head brassy, 

 polished, with distant punctures : eyes large, oval, entire, promi- 

 nent : antennas black, rather long; joints oblong-conic, terminal 

 one largest beyond the middle, abruptly narrowed so as to resem- 

 ble a twelfth joint; tip acute : labrum blue, bilolate, lobes divari- 

 cating : palpi black, not remarkably dilated at tip : thorax gla- 

 brous, brassy, polished, punctured each side, distinctly wider be- 

 fore the middle: scutel hairy: elytra pale olivaceous, [303] 

 tinged with brassy, slightly rugose : two slightly elevated, obso- 

 lete lines : feet rufous, knees and two anterior pairs of tibia 

 blue : tarsi fuscous. 



Length three-fifths of an inch. 



Very much resembles the preceding species, but differs by 

 many characters, particularly in the form of the thorax, in the 

 color, polish, and hair of this part and the head, in the form of 

 the antennas, &c. 



In the bilobate form of the labrum, these two species differ 

 from the other species of this genus ; their palpi are somewhat 

 similar to those of Zonitis and Nemognatha, but the second joint 

 of the antennae is minute, and the body is elongated. 



7. L. segmenta[ta]. — Black; beneath, segments edged with 

 cinereous. 



Inhabits Arkansa. 



Body black, covered by very numerous, short, prostrate black 

 hairs : head with an obsolete, hardly perceptible, rufous, abbre- 

 viated, frontal line ; anterior edge of the clypeus somewhat pale ; 

 beneath, and each side before the eyes, covered with cinereous 

 hair; antennae, second joint two-thirds the length of the third 

 joint : thorax anterior and posterior edges cinereous ; an impressed 

 longitudinal line : beneath, incisures, excepting those of the feet, 

 margined with cinereous hair. 



Length four-fifths of an inch.
