The existence of the type of Say, and its identity with the type 

 of L. Julia, stated by Mr. Uhler, secures this species. The typical 

 L. exusta has two pale bands on the thorax, which are not bluish in 

 the adult ; but I am unable to discover specific characters, and con- 

 sider both forms as belonging to the same species. Even L. de- 

 planata seemed to be a dwarfish southern form, but there are diff- 

 erences in the genital parts, probably important enough to separate 

 the two species. A full description of L. Julia, d, ?, by Mr. Uhler, 

 is given, Stett. Z., xxviii, 92.
