Polydesmus laurze, sp. n. 
. Colour of upper surface uniformly clear carneous; antenne 
and legs ochraceous with faint tinge of pink; shining. 
Body moderately wide and fiat, narrowed anteriorly and

nearly straight and sub-parallel, the sides evenly and strongly

The rest of the tergites normally sculptured, but wholly 
smooth. The anterior angles of the keels manifestly rounded, 
the posterior angles strongly produced only at the posterior end 
of the body; lateral margins entirely smooth and without den-

Copulatory feet of the male (fig.) conspicuous; basal segment 
large and stout and forming with its 
elllow of the opposite side a two-sided 
receptacle for the protection of the distal 
segments when at rest; second segment 
wide at the base and furnished poste-

hairs, produced distally into a lightly 
curved, strong piece which bears at the

distal segment very long slender and strongly curved at the
