8. C. confinis, sp. n. 



Ovate, brassj'', anteunai, four anterior legs, and posterior tibi.ne 

 red ; surface alutaceous, head smooth, thorax closel3^ but lightly 

 punctate, elytra not very deeply striate. L. .055-.06. North and 

 South Carolina (Zimm. n. 5027). 



Very like C. texana, but about half the size. 



9. C. pulicaria {Mels.)i Proc. Acad. iii. 167 {fide Zimm). 



Rather narrowly oval, brassy, base of antennae, four anterior legs, 

 and posterior tibiae red, surface alutaceous, head and thorax opaque, 

 this very obsoletely punctulate with deeper punctures along the 

 base ; elj'tra clearly punctate, striate, shining. L. .06. North 

 Carolina (Zimm. n. 5440), Texas (Belfr. n. 702). 



10. C. elongatula, sp. d. 



Elongate oval, narrow, pointed, black shining, legs and antennae 

 ferrugineous ; head and thorax alutaceous, ver}^ sparsely punctu- 

 late, this transverse, side straight ; elytra clearly punctate striate 

 scutellar striie reaching the middle. L. .06. 



Very unlike the other members of the genus by its depressed 

 form like orchestris, the intermediate tibiae are dentate as well as 

 the posterior. Colorado (Lewis). 



EUPLECTBOSCELIS, g. n. 



Allied to Chsetocnema, but distinct by the posterior tibi sulcate 

 throughout. The clypeus is strongly reflexed and thickened in 

 front, the antennae not very approximate, long, 2d joint quite 

 short ; thorax not impressed, elytra confusedly striate ; posterior 

 tibiae distinctly sulcate throughout, the sides ciliated, and the ex- 

 ternal edge with a tooth before the apex. I have been obliged to 

 form this genus for a Lower California species, which has much the 

 appearance of a Eumolpide. 



1. E. zanti, sp. n. 



Oblong ovate, ochreous, tinged with purple, tibiae and tarsi 

 brown ; head punctate on either side, disk smooth, shining, eyes 

 large, thorax transverse, not emarginate in front, sides straight, 

 base margined, disk unequal, sparingly punctate; scutellum smooth, 

 shining ; elytra thickly and closely substriate punctate ; clothed 

 beneath with a short gray pubescence (as in Disonycha). L. .24- 

 .25. Lower California (Xantus). 



J' First joint of four anterior tarsi broadly dilated.
