FAMILY IT. 



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



Small piceous or bronzed species closely allied to Cymindis, and 

 differing principally in having 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.
