I have examined two females of this species from Ludington, Michi- 

 gan, collected by Mr. 1ST. B. Pierce. 



Subgenus Pseudojulus, subgen. nov. 



16. Parajulus obtectus, sp. nov. 



Julus impressus McNeill, Proc. U. S. Nat. Mus. ; 1886. 



Color as in J. impressus, but more bright and not so dark. Robust, 

 attenuated before, not smooth, nor pilose. Vertex with a short median 

 sulcus, setigerous foveolae present. Antennae long, somewhat exceed- 

 ing the width of body. Eyes distinct, triangular or trapezoidal in the 

 larger specimens; ocelli numerous, 40-55, arranged in 7-9 series. Seg- 

 ments, 50-55. Sides of first segment striate. Other segments deeply 

 striate, upper surface as in impressus, but the striatious not so deep. 

 Last segment produced into a rather large, stout spine, which projects 

 beyond the anal valves; anal valves smooth, scarcely marginate ; anal 

 scale moderate, obtusely triangular. Eepugnatorial pore large, not 

 touching the transverse suture, which is deeply emarginate. Pairs of 

 feet, 80-95, extending beyond sides of body, moderately slender, 

 sparsely pilose. Male: Mandibulary stripes not much produced be- 

 neath. First pair of legs small, cone-like, not uncinate, sparsely pilose. 

 Coxa} of the second pair of test not produced into peculiar appendages. 

 Margin of the seventh ventral segment not much produced. Genitalia 

 concealed. Length of body, 18-35 mm ; width, 1.8-2.5 mm . 



Habitat. — Bloomington, Indiana, and Pensacola, Florida. 



I have examined numerous. females of this species, but only a few 

 males, and I have deemed it best not to give a description of the geni- 

 talia. 



This species is the type of the subgenus Pseudojulus. 



17. Parajulus varius, sp. nov. 



Light chestnut, a median and a lateral row of spots; segments dark 

 above, with yellow lines; a dark band between the eyes, also two large 

 pale spots, with two smaller ones behind them; vertex or occiput with 

 long, irregular pale spots; feet pale. Slender, not smooth or pilose. 

 Vertex finely wrinkled, a median sulcus, setigerous foveolae absent. 

 Antennas moderate, exceeding the width of body. Eyes distinct, tri- 

 angular; ocelli numerous, 40-75, arranged in 7-9 series. Segments, 

 50-55. Sides of first segment striate. Other segments not deeply 

 striate beneath, finely wrinkled and striate above. Last segment pro- 

 duced into a moderate, robust spine, barely passiug the anal valves; 

 anal valves not marginate; anal scale triangular, large, sparsely pilose. 

 Bepngnatorial pore moderate, not touching the transverse suture, 

 which is straight or nearly so. Pairs of feet, 75-90, scarcely extending 

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