(PI. Ill, %. 9.) 
Pule.v longispinus Wagner (1893, p. 355, t. 6, fig. 1, $, West Turkestan, off Erinaceus 
spec.)-, Baker (1904, p. 437). 
This is the only species known in which the episternum and sternum 
of the metathorax are fused, while at the same time the hindfemur is 
non-angulate ventrally near the base. 
Head. The rostrum does not quite reach the trochanter. The first 
segment of the maxillary palpus is longer than the third, while the 
second is longer than the fourth. There is a wide interspace between 
the first and second bristles of the subapical row on the occiput. The 
apical projection of the first antennal segment of the $ is broad, bearing 
one hair at the tip. 
Thorax. The bristles on the three tergites, on the two sides together, 
are respectively 17, 20, and 17. The mesosternite bears 3 bristles. 
The episternum of the metathorax has one bristle, while the epimerum 
bears two rows of 5 each, the bristles of the posterior row being very 
long. 
Abdomen. The anterior row of bristles on the first tergite consists 
of 4 and the posterior row of 8 bristles on the two sides together, 
the number of bristles on the following segments being 15, 14, 12, 12, 
10 and 10. The basal sternite bears a ventral pair and about 5 more 
bristles on each side, the other sternites having a single row consisting 
of 11, 8, 6, 6 and 6 bristles respectively. 
Legs. The comb of the hindcoxa contains 14 or 15 spines. The 
bristles on the upper side of the femora are exceptionally long. The 
mid- and hindfemora have one subapical bristle on the outer side, bearing 
a row of 8 and 9 respectively on the inner side. The bristles of the tibiae 
are very long and strong (PI. Ill, fig. 9). The longest apical bristle of 
the hindtibia extends beyond the apex of the first tarsal segment. In 
the foretarsus the second segment is twice as long as the first, while the 
first segment of the midtarsus is more than twice the length of the first. 
There are 6 bristles at the apex of the first hindtarsal segment which 
reach to the apex of the second or beyond, while there are 4 apical bristles 
on the second segment which reach beyond the middle of the fifth. The 
fifth segment is dilated at the apex, the lateral bristles being long and 
stout. 
Modified segments. $. The apical margin of the eighth tergite 
is nearly straight. There is a row of 9 bristles along the apical and
