(J. Ajiical spine of segments of foretarsus and two or three spines at the end 

 of the foretibia prolonged, but they are not so stout as in c/ii^rs/.'^ and vancouverensi.'i ; 

 first segment of liindtarsus much longer than the four other segments together ; 

 comb of midtarsus with very few moderately jirolonged bristles ; spurs of niidtibia 

 often with one or two spine.s. Abdomen with strongly marked mesial line on the 

 tergites as well as on the proximal sternites ; the lateral line of the sternites also 

 distinct. Paronychinra reduced, very short, without distinct lobes. 



S. Tenth abdominal tergite elongate-triangular, convex above, jiroximally 

 concave below, gently curved, extreme apex ibrming a short, bluntly jioiuted hook ; 

 sternite witli a long mesial lobe, which is slightly spatulate, witli tlie end rounded 

 and sinuate. tJlasper (PI. XL. f. u) somewhat less sole-shaped than in rJ/rr.si.^, 

 more narrowed distally ; harpe with a broad ventral lobe, which is concave ; from 

 the dorso-distal surface of this lobe originates a slender cylindrical ]irocess narrowing 

 to end, not sharjily liointed, homologous to the long process of (he harpe of //. 

 c/iersis, fanco/feerensi.i, etc. The penis-sheath diflers essentially iu being at the
