THE MYRIAPODA OF NORTH AMERICA. 



47 



ranged in a single, longitudinal, curved series behind the antenna\ 

 Segments, 35-45; sides of the first segment striate; other segments 

 moderately striate beneath; last segment rounded, pilose; anal valves 

 not marginate, pilose; anal scale small, rounded, pilose. Ivepugnato- 

 rial pore placed in the posterior division, small, not touching the trans- 

 verse suture, which is straight. Pairs of feet, 55-70; slender, not ex- 

 tending beyond the sides of body, sparsely pilose. Length of body, 

 9-12 mm ; width, 0.5-0.S mn '. 



Habitat. — Virginia, Florida, and Indiana. 



I have examined a number of females of this species from Blooming- 

 ton, In'd., and also the types of Julus lineatus McNeill, Mss. (Pen- 

 sacola, Fla.), but I can not find any difference between them and my 

 other specimens, which I have identified with minutus. Specimens not 

 in full color have the lateral row of spots bronze-red, and with a back- 

 ward-pointing branch, at the upper posterior side. 



Young individuals differ as follows: 



Length. 



Width. 



Eyes 

 (ocelli).

 ments.

 of legs.

Juhts punctatus Say, Jouru. Acad. Nat. Sci. Phila., 102, 1821 (preoccupied). 

 Julua stigmatosus Brandt, Recueil. 88, 1840. 



Pale brown: posterior border of segments dark; a lateral row of 

 brown spots; antenna' dark, feet pale. Slender, smooth, shining, not 

 pilose. Vertex without a median sulcus, setigerous foveohe present. 

 Antenna* subclavate, exceeding the width of body. Eyes distinct, tri- 

 angular or subrotund; ocelli 20-40, arranged in 5-7 series. Segments, 

 35-45. Sides of first segment striate. Other segments moderately 

 striate beneath: last segment smooth, obtusely rounded, pilose; anal 

 valves not marginate, pilose; anal seale small, rounded, pilose. Ee- 

 pugnatorial pore small, placed in the posterior division, not touching 

 the suture, which is straight. Pairs of feet, 50-75, slender, extending 

 beyond the sides of body, sparsely pilose. Male: mandibulary stipes 

 not much produced beneath. First pair of legs short and thick, unci- 

 nate, sparsely pilose. Genitalia exposed. Length of body, 8-13 m,u ; 

 width, 0.5-0.S""". 



Habitat. — Virginia and Indiana. 



I have examined about a dozen speeimeus of this species. It varies 

 somewhat in the shades of color, some being almost black. Only hav- 

 ing one full grown male, 1 have not attempted to give a description of 

 the genitalia. 



One young specimen differs from the adult as follows: 



Length, 7 , "" , ; width, .4"""; eyes (ocelli), 19-5; segments, 33; feet, 39.
