of the cariiije become first straight, the corners sub-rectangular, and then more and 

 more bent caudad, the angles becoming more and more strongly produced caudad. 

 The processes of the seventeenth and eighteenth somites are strongest, those of the 

 nineteenth much smaller and more rounded and this entire segiTient o\'erlapped and 

 essentially wholly covered by the preceding one. The cariti.T more strongK' devel- 

 oped and produced than in tunvexa. 



Repugnatorial pores as usual in the family. 



Length of type (male), about 31 mm.; width, 5.5 mm. 



Lncalily. California. One male taken in April, 1893, the precise place unknown. 

 I'arajiilus aritis sp. no v. 



The general color effect is brown. Each somite is darker in a broad band across 

 dorsum, where especially in the anterior region it is blackish, and down the sides, 

 the band somewhat nearer the anterior edge than the posterior and becoming paler in 

 going ventrad. This dark band embraces on each side of the median line above a 

 short transverse light mark, between the ectal end of this and the repugnatorial pore 

 a larger oblique light mark, while below the pore is a much larger light area narrow- 

 ing ventrad and more or less covered witli a network of dark lines, and a large area 

 farther ventrad, about midway between the preceding one and the legs, which is not 

 sharply limited, the enclosing anterior and posterior dark stripe being thin. The 

 head is light excepting a broad dark band between the eyes and extending down 

 between the antennce, this dark area embracing above and close to the median line 

 a pair of small light areas which are farther from each other than each is from 

 the corresponding antennal socket. At the vertex the usual areolation. First tergitc 

 with a darker anterior and posterior band, these extended at iniddle line, the rest 

 of the plate areolated. Legs yellow. Antennae dustky. 



Eye patch black; subtriaiigular, with the posterior and anterior sides convex. 

 Ocelli in seven or eight subvertical series, about fifty-six in number: e.g., 10, 10, 9, S, 

 7, 6, 4, 2. 



The first dorsal plate in the male is moderate, the lower margin slightly convex, 

 of medium length, the corners well rounded. Lower border and lower part of antcrim 

 one margined, the caudal one more vaguely so, the elevated ridge of the lower margin 

 broader anteriorly than posteriorly. Second segment in male not produced below 

 the first, the lower ridgelike projection being on a level with the edge of the first 

 tergite. Anterior somites strongly striate beneath, the stri^ becoming sidely separ- 

 ated in going dorsad toward the pores. 



Repugnatorial pores widely separated from the suture which opposite it is straight, 

 not at all curved or emarginate. 



Anal tergite triangularly narrowed caudad, the ti]i exceeding the anal valves 

 moderately, but not at all spine-like. 



The cardo of the mandible in the male in outline in lateral view is sub<iuadrate, 

 being broadly truncate below with the caudoventral corner moderately bulging and 

 strongly rounded, not at all produced below. The first legs are enlarged moderately 

 and curved in the usual way. The second legs reduced and elevated as usual. 



The anterior gonopods of the male are elongate wide bodies somewhat clavately 

 widening and at the satne time thickening distad where they are in contact at the 

 median line and largely conceal the posterior gonopods from below and in front much 

 as in peniisyh'aniciis ; each is truncate distad, and the distal end crossed by a trans- 

 verse furrow which continues down the mesal side and in part embraces the second
