XL. CoRYMBiTES Lat. 1834. (Gr., "a brush or pencil.") 



This genus conii)rises a large heterogeneons group, into which 

 have I)een shifted species widely different in form, size and color. 

 They all agree in having the clypens more or less llattened and not 

 margined in front; tarsal joints without lobes, the claws simple; 

 prosterntim with a long lobe; hind eoxal plates narrow on the cmter 

 end. The genus is badly in need of revisitm. and no literature ex- 

 cept the Avidely scatt'^red descrii)tions is available. Abont 80 spe- 

 cies are known from the [Tjiited States, of which Ihe following have 

 lieen taken or perhaps occtir in Indiana :
