Hippodamia extensa Mulsant, Species des Coleopteres trimeres securipalpes, 

 p. 15, 1851. 



This species probably has the most limited range of any North 

 American species, as apparently it is confined to the salt marshes of 

 San Francisco Bay region, California. The writer has examined 

 specimens from Alameda and Milbrse (E. C. Van Dyke).

This common Eastern species has been examined from Melrose 

 Highlands and Forest Hills, Massachusetts (P. H. Timberlake) ; 

 West Springfield, Massachusetts (H. E. Smith) ; Salisbury, North 

 Carolina (R. A. Vickery) ; and Tower City, North Dakota (Miriam 

 W. Reeves). 



13. Hippodamia species. 



One male from Soda Springs, Idaho, remains undetermined. It 

 runs to siibsimilis in Casey's tables, and may possibly be that species, 

 although subsimilis on the other hand might as likely prove to be a 

 form of 5-signata. 



ON THE GENUS RHODESIELLA C. F. ADAMS 

 (DIPTERA). 



By M. Bezzi, 



Turin, Italy. 



In 1905 Mr. C. F. Adams erected the genus Rhodesiella for a 

 small South African fly collected in Rhodesia, near Salisbury, Jan- 

 uary, 1901, by Mr. Frank L. Snow. The new genus was placed in 

 the family Agromyzid^e, but nothing was said about its natural affini- 

 ties; the name has subsequently appeared only twice in the diptero- 

 logical literature, besides the citation in the Zoological Record for 

 1906, vol. XLIII, p. 391. It was conserved by me in the family 

 Agromyzidse in my Catalog of the African Diptera (1908, p. 194), 

 but Prof. Melander has removed it to the Milichiinse in his table of 

 the genera of the subfamily (1913, p. 237).
