stipes not much produced beneath. First pair of legs small, strongly 

 uncinate. Genitalia concealed. Length of body 11.4-13.5 mm ; width, 



7_S mm 



Habitat. — New Harmony, Indiana. 



I have examined two males of this species, collected by Dr. Eichard 

 Owen, of New Harmony, Indiana, after whom the species is named. 

 This species belongs to the sub-genus Allajulus as defined by Latzel.

Julus virgatus "Wood, Proc. Acad. Nat. Sci., Phila., 14, 1864. 



Fulvous-brown, a black median and two lateral bands, a dark band 

 between eyes; joints of antennae tipped with black, feet pale. Slender, 

 nearly smooth; a row of hairs along the posterior border of each seg- 

 ment. Vertex smooth; a faint median sulcus; setigerous foveolse pres- 

 ent. Antenna moderate, subclavate, equaling width of body. Eyes 

 distinct, triangular or trapezoidal ; ocelli 25-40, arranged in 6-7 series. 

 Segments 30-35. Sides of first segment marginate; other segments 

 striate both above and below, but more so in the latter; last segment 

 rather sharply rounded, sparsely pilose ; anal valves scarcely marginate, 

 smooth, pilose; anal scale triangular, rather large, pilose. Eepugna- 

 torial pore small, partly concealed by the transverse suture, which is 

 moderately excised. Pairs of feet, 50-65, not equaling width of body, 

 rather stout, sparsely pilose. Male: mandibulary stipes moderately 

 produced beneath. First pair of feet short, scarcely thickened, strongly 

 uncinate. Genitalia half concealed; anterior plate entirely concealed, 

 except the end; large, flat, the ends turning outwards, rounded; pos- 

 terior plate composed apparently of three pieces, strongly twisted to- 

 gether at base, anterior part expanded at the end, ending in an inward 

 curving spine, middle part not expanded, end pointed, posterior blade- 

 like, pointing inwards and projecting out on the inner side of the others, 

 the tip rounded. Flagelrum not detected. Length of body, 8-12 mm ; 

 width, .7-l mm . 



Habitat. — Pennsylvania, District of Columbia, and Indiana. 



I have examined numerous specimens of this species from Blooin- 

 ington, Indiana, where it seems to be common in orchards and pastures 

 having a thick growth of grass. 



The females are considerably more robust than the males.
