 cluding a new species of Derbe and other insects, accompanied by 

 notes on the habits of a species of Cassida ; another of a Cercopis, 

 called the Cow-ant, (from emitting a saccharine fluid which the 

 ants greedily drink,) and .on several species of parasitic Hymenoptera 

 (including a species of the genus Elasmus) reared from the cocoons 

 of a small moth.
