4. Scytonotus granulatus (Say). 

 Not uncommon. 



5. Polydesmus serratus Say.

 Not syn. — Poly, serratus Wood. Trans. Amer. Philos. Soc, 215, 1865 ( P. moniliaris 



Koch). — Poly, canadensis McNeill, Proc. U. S. Nat. Mus., 324, 1887 (Pensacola, Fla.; 



P. nitidus Bollman). Poly, canadensis Bollman, Ann. N. Y. Acad. Nat. Sci., 107, 1888 



(Knoxville, Tenn.; P. branneri Bollman). 

 In this paper I have regarded Poly, canadensis as representing the true serratus of 



Say. The Poly, serratus of Wood, which has the lateral carina hnely serrate, is 



probably Poly, moniliaris Koch. 



6. Fontaria virginiensis brunnea Bollman. 

 Fontaria virginiensis brunnea Bollman. Amer. Nat., 82, 1887 (Ft. Snelling, Minn.). 



Besides the type, I afterwards received another specimen that was 

 not in color. 



7. Geophilus bipuncticeps Wood. 



One female was found in the collections. 



8. Lithobius minnesotae Bollman. 



Lithobius minnesotae Bollman. Amer. Nat., 81, 1887 (Ft. Snelling, Minn.); Bollman, 

 Proc. U. S. Nat. Mus., 255, 1887. 



Only the type of this species was obtained. 



9. Lithobius howei Bollman. 



Lithobius howei Bollman. Amer. Nat., 81, 1887 (Ft. Snelling, Minn.); Bollman, 

 Proc. U. S. Nat. Mus., 254, 1887. 



Only the type specimen was found. This species is closely related to 

 politus McNeill, but until good material can be obtained it will be best 

 to let it stand as it is. 



B. — Winona. 



The collections received from this locality were made during 1S86 and 

 1887. As the material was collected at all suitable times in the year, 

 I have been enabled to present a rather exhaustive list of the myria- 

 pods of this vicinity. 



The greater bulk of the material consisted of specimens of Lithobius 

 forficatm.
