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

 gan, collected by Mr. N. B. Pierce. 



Subgeuus Paeudojulus, sub gen. uov. 



16. Parajulus obtectus, sp. nov. 



Julus impresses McNeill, Proc. U. S. Nat. Mus., 1886. 



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

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

 sulcus, setigerous foveolre 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 7-0 series. Seg- 

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

 striate, upper surface as in impresstts, but ^tlie striations not so deep. 

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

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

 scale moderate, obtusely triangular. Repugnatorial pore large, not 

 touching the transverse suture, which is deeply eniarginate. 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. 

 Coxae of the second pair of feet not produced into peculiar appendages. 

 Margin of the seventh ventral segment not much produced. Geuitalia 

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



Habitat. ]>loomington, 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- 

 tal i a. 



This species is the type of the subgenus Pxeiulojub.ix. 



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 foveoliB absent. 

 Antenna? 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 passing the anal valves; 

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

 Eepugnatorial 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
