In the male the seventh segment does not differ especially 

 from the sixth segment. The tergum of the eighth segment 

 is subtriangular, with curving sides, and the pleural mem- 

 brane is especially broad. The lateral portions of the ster- 

 num project caudad much beyond the caudal tip of the ter- 

 gum, as two, horny, double-pointed, thin, plate-like pro- 

 cesses, called the ''false claspers." These processes are not 

 articulated with the sternite, and are not movable as are the true 

 claspers of the ninth segment, but are projecting parts of the 

 sternum, and thus are not homologous with the body append- 

 ages. The tergal, lateral, and sternal walls of the ninth 

 segment are concealed within the eighth segment, but cer- 

 tain processes or appendages belonging to the ninth segment 

 are conspicuous. From the tergum a conspicuous, caudad- 

 projecting, tongue-like process arises, whose distal half is 

 divided longitudinally into two, lateral flaps or lobes, whose 

 tips are diagonally truncate. This dorsal process with 

 divided, distal portions is called the tegumen or sicula. Be- 

 tween the false claspers, there may be seen a pair of dark 

 pointed processes. These are the tips of the true claspers or 

 harpagones. Break away one of the false claspers, and the 

 true clasper of that side will be mostly exposed to view. It 

 consists of a subquadrate, plate-like part, with a median, 

 thickened and ridged portion lying on its mesal or inner 

 aspect ; projecting caudad from the. caudo- ventral angle of 

 the subquadrate part and continuous with the ridge of the 

 mesal face, there is a slender, but strong-pointed process, con- 

 cave outwardly, and bearing on its outer surface near the 

 tip a number of fine, transverse lines. Projecting caudad 

 from the dorso-caudal angle of the subquadrate part of the 

 true clasper there is a smaller and rather triangular process.
