4. Scytonotus graiiulatus (Say). 

 Not uncommon. 



5. Polydesmus serratus Say.

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

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

 P. nil'idus P>ollniau). Poly, canadenais Bollrnan, Ann. N. Y. Acad. Nat. Sci., 107, 1888 

 (KnoxriUc, Trim.; P. branneri Bolhnan). 



In this paper I have regarded Poly, canadcuxis as representing the time serratus of 

 Say. The Poly, xerratim of Wood, which has the lateral carime nnely serrate, is 

 probably Poly. wonU'no-ls Koch. 



6. Fontaria virgiiiiensis brunnea Bollman. 



Fontar'nt rh-<ji/ii< UN!* hrmnn-a Bollmau. 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 Bollmau. 



Litholrius minnesotoe 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 Bollmau. 



LithoMiis howei Bollmau. Amer. Nat., 81, 1887 (Ft. Snelling, Minn.); Hollman, 

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



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

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

 to let it stand as it is. 



B. WlNONA. 



The collections received from this locality were made during 1886 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 Lith obiu. s- 

 forficatm.
