c?. Apical 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/iersis and rancourerensis ; 

 first segment of hindtarsus much longer tlian the four other segments together ; 

 comb of midtarsus with very few moderately jirolonged bristles ; sjuirs of uiidtibia 

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

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

 distinct. Paronychium reduced, very sliort, witliout distinct lobes. 



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

 concave below, gently curved, extreme apex forming a short, bluntly jjointed hook : 

 sternite with a long mesial lobe, which is slightly spatulate, with the end rounded 

 and sinuate. Clasper (PI. XL. f. 5) somewhat less sole-shaped than in cJiersiti, 

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

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

 to end, not sharply pointed, homologous to the long process of the harpe of //. 

 chersis, rcoico/trerensis, etc. The penis-sheath differs essentially in being at the 

 end widened laterad into a sharply pointed, triangular flap (PI. XXIX. f. 0) ; the 

 a])ex is produced into a heavy, short, curved, tooth-like process.
