HABITAT. Massachusetts in July; Middle States to Texas; New 

 Mexico; District of Columbia, iu August; Texas in May and June. 



The types are all in the British Museum. It is possible that Hyamia 

 may have another type, not congeneric with perditali*. In that case 

 Legna must be used, as the type and only species is seuiilineata. Spar- 

 galoma Grt., is antedated in any case. H. perditalis is from "locality 

 unknown," but is evidently this species.
