N. B.— The fignres can not be said to show the specific character ac- 

 curately. The specimens in ni}^ possession, wliich I identify with the species, 

 are all too .yoimg and can not be shown as to repi'esent the species in a 

 monograph. Hence, the original figm-es, though far from satisfying, are here 

 taken.
