The Non-Combed Eyed Siphonaptera 
fifth. The clasper (PL IV, fig. 7) has two slender free processes, both 
bearing hairs at the apex, the upper one bearing also two longer bristles. 
A third, smaller, process, placed beneath the two free processes, is not 
separated from the body of the clasper. The manubrium is short and 
slender. The ninth sternite (ix. st.) is distinctly dilated at the apex, the 
ventral margin being there rounded. The internal plate of the penis is 
rounded at the apex.— $ . The apical edge of the eighth tergite is rounded. 
At the apical edge and above the ventral edge there is a row of 8 to 10 
bristles, the apical margin bearing in addition from 5 to 8 smaller bristles 
which are placed on the inner side of the segment. On the lateral 
surface there are, besides, 5 to 10 bristles, of which two, rarely one, are 
placed beneath the stigma, but some distance from it. 
Length. 1—-T4 mm., $ 1*4—1‘7 mm. 
This species was also found commonly by the junior author on 
various hosts in Egypt and the Sudan, as detailed below:— 
Shendi, Sudan, off Gerbillus pygargus, Dipodillus watersi, Jaculus 
jaculus, Lepus aethiopicus and Erinaceus aethiopicus. 
Kerma, Dongola, off Gerbillus pygargus. 
Shereik, N. Sudan, off Gerbillus pygargus and Acomys witherbyi. 
Khartoum, off Gerbillus gerbillus (collected by Dr A. Balfour). 
Albumar, Bir Victoria, Natron Valley, off Ictonyx libyca. 
Zaghig, Natron Valley, off Gerbillus tarabuli and Jaculus jaculus. 
Bir Victoria, Natron Valley, off Lepus rothschildi and Gerbillus 
tarabuli. 
Mt Mulluk, Natron Valley, off Meriones sellysii. 
(4) Loemopsylla pyramidis Rothsch. (1904). 
Pulex pyramidis Rothschild (1904 b, p. 3, n. 3, Natron Valley, Lower Egypt, off 
Jaculus jaculus)-, Baker (1905, p. 143). 
Only one $ is known to us. The specimen very closely resembles that 
sex of L. cleopatrae and is perhaps only an exceptionally large individual 
of that species. The rostrum, however, does not reach the trochanter; 
the episternum of the metathorax bears only one long bristle, besides 
some minute hairs; and the hindtibia has two additional lateral bristles 
between the lateral row and the dorsal edge. The </ might possibly be 
abundantly distinct from L. cleopatrae. 
One $ off Jaculus jaculus, found by the junior author at Bir Victoria, 
Natron valley, Lower Egypt, on March 9th 1903.
