 is sharply euiarginate. Pairs of leet, TO-lKi, ecjualinji width of body,

 loi'g, parallel appendajje, the tip rounded, very sparsely pilose. Geni 

 talia fully exposed, com [)osed of three ])ieces: anterior i)late moderately 

 lonjjf, round, slightly twisted, the end scarcely clavate, turning out- 

 wards, densely pilose; nii«l<lle i)late large and thin, forming a tube; 

 posterior j)late sickle shaped, the end bitid, inner or under edge strongly 

 serrated, a thin lauc«'olate spine sj)ringing tVom the base. Flagelluui 

 not detected. Length of body, lS-32"""; width, 1.8-2""". 



llahitHt. — Cleorgia, Illinois, Indiana, Michigan, and Minnesota. 



I have examined s])ecinuMis of this species from Ludington, Mi»higan, 

 and Chauncey, Indiana: th<»se from the latter place are larger and 

 darker in color. 



Wood's plate of the genitalia does uot show the serrations, etc., of the 

 l)osterior plate, nor the true form of tin; middle plates. 



Specimens not adult vary as follows: 



12. Parajulus ellipticus, sp. nov. 



Color almost similar to that of J. iiupres-^im, but daiker, feet pale. 

 Moderately robust, not smooth or pilose, siiining, somewhat attenuated 

 before. Vertex smooth, a median sulcus, setigerous foveohe present. 

 Antenuie not eijualing Avidth of body, densely pilose. Eyes distinct, 

 almost elliptical, ocelli somewhat <'rowded, 4(»-48, arranged in ()-8 series. 

 Segments, 47. I'irst segn)ent moderately large, sides striate. Other 

 segments rather deeply striate, rough, with numerous short wavy stride. 

 Last segment produce*! into a moderately large, robust spine, pr6iecting 

 beyond the anal valves, sparsely i)ilosc; anal valves smooth, not mar- 

 ginate, sparsely pilose: anal scale obtusely triangular, rather large. 

 Repugnatorial pore small, not touching transverse suture, which ia
