Ixix] ENTOMOLOGICAL NEWS 93 On a Collection of Centipedes from Wisconsin (Chilopoda) By R. E. CRABILL, JR., Smithsonian Institution, Washington, D. C. The following records constitute one of the two known faunal reports on the significant and polyglot chilopod population of Wisconsin. 1 It has been made possible through the energy and generosity of Dr. and Mrs. Herbert W. Levi of the Museum of Comparative Zoology at Harvard. I should like to express my gratitude to them for the sizable collection of carefully preserved specimens of which most of the present localities are repre-sentative. Though this report is admittedly fragmentary and introduc-tory, in my estimation it still suggests at least that the state sup-ports a rather versatile fauna, more versatile than the mid-western states' immediately to the south. This is apparent from the coexistence in Wisconsin of typical Austral and Transitional species, the latter evidently more prevalent than the former. For example we find such cold-adapted forms as Escaryus urbi-cus, Lithobiiis jorficatus, and Taiyubius harrielae but also such Austral species as Arenophilus bipuncticeps and Sosibius sp., the advance of the latter no doubt being encouraged by the same edaphic and particularly climatic conditions that support the ex-tension of the midwestern prairie into the extreme southeastern counties. In the ensuing discussion collection stations are identified by a formula following each species name. A capital letter refers to a county, and the associated number to a locality within that county. The list of counties below is arranged as they occur from north to south : an asterisk indicates a Levi collection, the absence of one that the record is drawn, instead, from the literature. 1 An earlier report is D. C. Matthews' unpublished doctorate thesis, "The Chilopoda of Wisconsin," The University of Wisconsin, Thesis, 1935.
