hue edge of first tergite but little elevated. The crenations or lobes broad 

 and low. Surface but little elevated, densely finely tubercular throughout; 

 with the usual two transverse rows of larger tubereles; these prominent, large, 

 ami rounded, the first row embracing four, the second six of which the two 

 inedian ones are adjacent to the caudal margin. The surface of the tergites 

 in general strongly densely tubercular. Four longitudinal rows of larger, more 

 prominent tubercles as usual; three tubercles in each series on each tergite but 

 the most caudal of these lower and often inconspicuous or almost obliterated 

 as such; in addition on each side of the non-porigerous tergites between the 

 lateral row and the lateral lobes of the keels a single large tubercle in line with 

 a large elevated tooth projecting from the caudal margin. Keels laterally 

 coarsely serrate, there being three teeth on the keels of the second to sixth 

 termites inclusive, and thereafter three on the non-porigerous and four on the 

 porigerous keels. Caudal angles of posterior keels more and more produced 

 caudad, the processes of the fifteenth to nineteenth in particular long and 

 subacute; the processes of the eighteenth and nineteenth keels very slender. 

 The caudal margin of each keel just mesad of the caudal corner with a large 

 obtuse tooth, the edge mesad of this weakly serrate; but caudad the entire 

 caudal margin of tergites more strongly crenate, the crenations finally be- 

 coming more acute and on the eighteenth and nineteenth projecting as acute 

 teeth. Pores above and well removed from margin, on base of caudal lobe, 

 the surface about and beneath each one elevated as a low rounded mound. 

 Venter of metazonites subdensely pilose. Last tergite large, triangular; at 

 middle above two large conical tubercles and on each side in line with them a 

 very slender marginal tubercle or cone; just proximad of the distal end a 

 transverse row of four much smaller tubercles, the*one at each end marginal, 

 setigerous; on each lateral margin toward base a long slender tubercle bearing 

 a long stout seta; four long setae at tip of cauda. 



The apical pieces of the gonopods extending forward to the caudal edge of 

 the ridge between the anterior legs of the sixth segment; they are rather 

 broad flattened blades; the two terminal branches are both thin and flattened, 

 blade-like, with the outer one curving mesad above the tip of the mesal one 

 which is curved a little in the opposite direction. 



Length (female), to ca. 15 mm.; width, 2.5 mm.
