Tribe II. PEDILINI. 



Very neat, oljlong: or elongate hlaek (rarely brown) beetles hav- 

 ing the thorax usually yellow, sii1)globose and j)olished; mandibles 

 truneate: antenna' (in our speeies) slender and subserrate; maxil- 

 lary palpi feebly dilated; next to last joint of tarsi bilobed. The 

 males have six distinct ventral segments and often have the tips of 

 elytra impressed and polished. 



The tribe is represented by the single genus Cnvplnjra Say. 

 Casey ha.s substituted for this the old name l'(<lih(s. htil Horn has 

 given (Trans. ITI, 278) good reasons why Say's name should stand, 

 so it is here retained. 



TTT. CoRPiiYRA Say. 1835. 



Horn in his latest paper on Corplium (loe. eit.) lists 20 speeies 

 as belonging to the North American fauna. Dury has shown* that 

 a numtjer of these are very closely related and probably synonym- 

 ous. The thorax in all species is ellii)tical with all the angles 

 rounded: in the wholly black species it is somewhat wider and less 

 convex than in the others. Eight of the '20 foi-ms have been taken 

 in th(^ State, while another may occur.
