Remarks: Bofhynm gibbo.'^m (DeGcer) was described from Penii- 

 sylvaiiiu in 1774. Since no other species of similar appearance is 

 known to occur in Pennsylvania, we can be reasonably sure of its 

 identity even thougli the original description might apply to other 

 species equally well. 



It is surprising that tliis species does not occur in Florida, but 

 among the many specimens seen from that State not one has been 

 gibbosus. There have been a number of published records of gibbosus 

 in Florida, notably Blatchley (1928). However, the only specimens 

 labeled L. gibbosus (DeGeer) from Florida now remaining in the 

 Blatchley collection are negUdus (LcConte).
