[CONTINUED IS OUE XEXT.] A NEW BARK LOUSE ON THE OSAGE ORANGE. [Fig. S.]. -(a) light brown and white; (b) blooil brown lunl At figure 8, b, we have represented a new species of bark louse {Lecanium maclurm,sj n. sp.,) which lias recently appeared in consid- erable numbers on the twigs and leaves of the OsagCiorange at "Wilmington, AVill county, III., and also in the vicinity of Alton,in South Illinois.
