FAMILY IT. CAEABIM. 



LI. Apenes Lee. 1852. (L., "without wings,") 



Small pieeous or bronzed species closely allied to Cymindis, and 

 differing principally in haying the thorax lobed at base and the last 

 joint of labial palpi more broadly triangular. One species has been 

 taken in Indiana, while another doubtless occurs in the southern 

 counties.

 curs in open woodland, about the bases of trees and stumps.

 One small species represents this genus in the United States. 



275 (954). Pentagonica feavipes Lee, Trans. Amer. 

 Phil. Soc, X, 1853, 377. 

 Rather broad, resembling a small LeMa analis. Head 

 and elytra pieeous, very finely alutaceous; thorax, 

 basal portion of antennae and legs reddish-yellow; 

 sometimes wholly pieeous with pale legs. Thorax 

 short, twice as wide as long, sides strongly angulate.

 striate without punctures. Length 3.5-4.5 mm. (Fig.
