THE MYKIAI'ODA OF NOKTH AMERICA. 



r>5 



tenme long', equal to tin- width of body. Eyes distinct, triangular; 

 ocelli more or less prominent, 40-70, arranged in s-!> scries. Segments, 

 55-05. First segment with lour rows of setig'erous foveohe. sides striate. 

 Other segments moderately striate beneath, posterior division of each 

 segment marked with tine stri;e. Last segment produced into a short 

 spine, not projecting beyond the anal valves; not smooth, densely pilose; 

 anal valves not nmrginate, rough, densely pilose; anal scale, small, 

 rounded, pilose. Kepugnatorial pore moderate, partly hidden by the 

 transverse suture, which is rather sharply emarginate. Pairs of feet 

 100-112, not extending much beyond the width of body, densely pilose. 

 Mole: Mandibulary stipes strongly produced beneath. First pair of 

 legs large, uncinate, the inner surface with numerous tubercles, pilose. 

 Ventral margin of the seventh segment not much produced. Genitalia 

 exposed; anterior plate thick, rounded, the end somewhat clavateand 

 scooped out, very pilose ; posterior plate strongly twisted and rolled, 

 the apex divided into three plates, the anterior lanceolate, not serrated, 

 the others broad and thin, with the edges strongly toothed. Flagellum 

 not detected. Length of body, 20-38 11111 ' ; width, 1.5-2""". 

 Habitat. Pennsylvania, A'irginia, and Indiana. 



I have examined numerous specimens of this species from Blooming- 

 ton, Indiana. Julus montanns Cope is identical with this species. 

 Specimens not adult range as follows: 



15. Paraiulus canadeiisis (Newport).

Dark brown, almost black, sides with a series of yellow, conglom- 

 erated spots: feet very pah-, antenna' scarcely paler. K'ather slender, 

 not smooth, shining, nor pilose. Vertex rough, a slight median sulcus, 

 setigerous tbveohe present. Antenna' short, about equaling width of 

 body. Eyes distinct, triangular; ocelli rather rlat, 43-50, arranged in 

 0-8 series. Segments, 50-57. First segment with sides striate. Other 

 segments moderately striate. numerous tailed-like punctations above. 

 Last segment produced into a large, strong, round, decmved spine, 

 sparsely pilose: anal valves scarcely marginate. pilose; anal scale tri- 

 angular, pilose. Kepugnatorial pore large, not touching the transverse 

 suture, which is broadly but not deeply emarginate. Pairs of feel. 

 SO-<K>, stout, not equaling the width of body, sparsely pilose. Length 

 of body, 18-25"""; width, -1 .;'-!.. ~>""".
