50. CALLIMOME THALASSINUM (Crosby) 



Figure 1 

 Syntomaspis thalassinus Crosby, Can. Ent., vol. 40, 1908, p. 143. 



Type locality. — New York. 



Host. — Harmolita, species. 



Type. — In the Cornell University collection. 



I have not examined the type of this species. There are in the 

 National collection 16 specimens of this species identified by A. B. 

 Gahan, whose identification I have confirmed. 



Distribution. — Ithaca, Amsterdam, Lake Keuka, Oneonta, Kingston, 

 Cranberry Creek, Remsen, Elmira, Lowville, Bluff Point, Cortland, 

 and Victor, N. Y., reported by Crosby. In the National Museum 

 are the following: Four females and eleven males reared from timo- 

 thy August, 1913. One male reared by C. N. Amslie March 26, 1914, 

 at Lewisville, Minn., recorded under Webster No. 8877. One female 

 and two males from Waterloo, N. Y., collected by W. J. Phillips and 

 recorded under Webster No. 9354. In the author's collection are 

 two females taken by A. E. Miller, July 15, 1921, in sweepings from 

 a timothy meadow on the Ohio State University farm, Columbus, 

 Ohio. 



The nearest known relative of Callimome thalassinum (Crosby) is 

 roJiweri which occurs on the western coast of the United States. The 

 two species may be separated by a difference in sculpture.
