MYRIOPODA FROM BURMA 393 
1.8 fergite marked (in front) by two sulci; the posterior of 
these distinct, the anterior very faint, both running parallel to 
the anterior edge; lamina rising gradually, with thickened and 
evenly arched anterior border, bearing on its surface piliferous 
punctures; the lower part of the tergite above the base of the 
lamina marked with fine strie. 
Anal tergite evenly rounded, without marginal notch, and 
small inner ridge; its inner surface finely granular — the 
granules, in the male, constituting with the rasping plate of the 
forceps a stridulating organ. 
Antenne with apical segment almost cylindrical. 
Legs with distal segment attenuate at 
the apex, with a single spine above the 
claw. : 
g'. Like the female, except in the 
form of the posterior legs. The legs in 
the hinder half of the body gradually in- 
crease in length from before backwards 
and alter in-shape at the same time. 
The two basal segments become very 
large, the third segment completely 
bent in the form of an arch and the 
distal segment dilated towards its extre- 
mity and thickly clothed with long 
hairs (fig. 6, B). 
The forceps are very peculiar in shape; 
in the 1.* pair (fig. 6, D) the carpal 
segment is long and cylindrical and 
the stout and short immovable dactylus bears a small tooth at 
the base; the movable dactylus has the apex bifid. In the 
2." pair (fig. 6, A, C, E) the carpus is very long and there is a 
rounded projecting tooth-like process over the base of the movable 
dactylus; this dactylus is composed distinctly of two segments of 
which the proximal is exceedingly stout at the base and bears 
on its posterior surface a plate covered with fine parallel ridges; 
the immovable dactylus is very short, and close to the base of 
Zephronia crepitans
