108 BULLETIN 46, UNITED STATES NATIONAL MUSEUM. 



This species is described from ten specimens, four females and three 

 males, from Brookville, Franklin County, and three females from Hagers- 

 town, Wayne County. It agrees with the eastern specimens of coriacea 

 iu having a broad yellow band along the posterior margin of each 

 segment, but the shape of the male copulation foot, especially the bifid 

 character of the basal spine, will serve to distinguish it from coriacea. 



23. Fontaria butleriana, sp. nov. 



Diagnosis: Related to Fontaria coriacea Koch, but the segments 

 strongly attenuated posteriorly ; size larger and width less in propor- 

 tion to the length; dark greenish black, with a narrow yellow line along 

 the posterior border of each segment. 



Habitat : La Fayette and Brookville. 



Type: U. S. Natioual Museum; No. 520, author's collection.

The above measurements, when compared with those of Fontaria co- 

 riacea clearly show the difference in size. 



This species is described from two females — one from each locality. 



It approaches very closely to Koch's figures of F. mrginiensis, and it 

 is probable that he has described this species as rirginiensis.
