metepimeron there are two rows of bristles, the anterior one of 
eleven and the posterior one of fifteen. 
Abdomen.—The first abdominal tergite bears a ctenidium of 
forty spines, similar to the ctenidium on the pronotum. On the 
IIl-V tergites there are ctenidia. The spines forming these 
combs are very short and stout, quite unlike those of the others. 
The numbers of spines in order are forty, thirty-eight, thirty and 
twelve. There are also two well-defined rows of bristles on each 
tergite, with a few minute bristles scattered at random between 
the rows. The seventh tergite is continued over the pygidium 
in a long spine and bears at the base of this spine the antepygidial 
bristles, five on each side. Sternites IJI-VII bear a few bristles, 
as follows, the figures being for one side only: 5; 4-4; 3-1-2; 
3-10; 5. 
Legs.—The spines on the anterior (outer) margin of the tibiz 
are unusually long and heavy. On leg II, the longest apical spine, 
situated at the outer angle, exceeds the first and second tarsal 
segments combined and is longer than the tibia itself. On leg 
III the longest apical spine is equal to some of the lengths of the 
first segment and one-third of the second. The apical spine of 
the first segment of tarsus III is equal to the second segment, 
while that of segment two equals segments three and four com- 
bined. There are four pairs of lateral plantar bristles and a 
fifth pair placed between the first laterals. The comparative 
lengths of the tarsal segments are as follows: 
Tarsus. Segments 1-5.

Modified Segments.—The seventh sternite is narrowed posteri- 
orly. The flaps of the seventh tergite are somewhat rectangular 
and bear ten bristles on the posterior margin. The eighth tergite 
bears at the upper part a row of eight heavy bristles, situated 
directly behind and under the antepygidial bristles. The stylet 
is short and cylindrical and bears at the apex one long bristle. 
The body of the receptaculum seminis is spherical. The appen- 
dix is of an equal diameter throughout and is curved about the
