Thorax.—The pronotum bears on its posterior margin a 
-ctenidium of 46 spines and also five rows of bristles. The meso- 
and metanota bear many bristles roughly arranged in seven rows 
on each. The pleural plates bear a few longer bristles. 
Abdomen.—The tergites are thickly set with many bristles, 
these not arranged in definite rows. The posterior margins of 
the third, fourth and sixth tergites bear combs of very short and 
thick spines, the numbers of the spines in the rows being 8, 4, 3. 
The antepygidial bristles are four on each side. Sternites III 
to VII are heavily armed with many bristles. 
Legs——The fore femur bears on the ventral (posterior) mar- 
gin proximally a pair of bristles and near by, a single bristle. 
Distally, there is a row of six bristles which extends across the 
apex of the femur to the anterior apical angle. The spines of 
the anterior margin of the fore tibia are in nine groups, the num- 
bers Of spines in’ the groups are as follows: 2, 2, 1, 2, 3, 3, 1, 
3, 3. At the posterior apical angle there are two groups of three 
spines each, the longest spine in the apical group nearly equaling 
the first segment of the tarsus. First tarsal segment with heavy 
bristles in eight groups, but as many of the spines are missing in 
the type and only specimen it is impossible to state the exact 
number. The plantar bristles of the fifth segment consist of 
five pairs, all lateral. The armature of the mid and hind legs is 
essentially like that of the fore leg. The apical row of bristles 
of the femora contains ten instead of six. The spines of the 
anterior margin of the mid tibia are grouped as follows: 2, 2,

spines. Plantar bristles as in the fore tarsus. The relative

Modified Segments.—The seventh sternite is produced on the 
sides posteriorly into a broad, truncate lobe, the base of the lobe 
is about six times its altitude. There are many heavy bristles on
