The Non-Combed Eyed Siphonaptera 
We have only examined two specimens received from Dr J. Wagner, 
taken off Gerbillus spec, at Tedschen, Transcaspia, in July 1893. 
(21) Loemopsylla ramesis Rothsch. (1904). 
(Pi. y, fig. e.) 
Pulex ramesis Rothschild (1904 b, p. 2, n. 2, t. 1, fig. 3, Lower Egypt, off Pachyuromys 
duprasi natronensis and Gerbillus tarabuli ); Baker (1905 a, p. 143). 
Likewise closely related to L. mycerini. The rostrum, however, is 
only as long as the maxillary palpus, reaching to the apical third or 
fourth of the forecoxa, and the genitalia of the </ are very distinctive 
(PI. V, fig. 6). The eighth abdominal sternite of the J 1 bears 2 long 
lateral bristles and a row of 2 to 4 ventral ones. The upper free 
process of the clasper is broad, truncate, bearing several long bristles at 
the apex and a number of shorter ones on the outer and upper sides. 
The third process is also broader and longer than in mycerini. 
A small series of both sexes from Bir Victoria, Natron Valley, Lower 
Egypt, off Pachyuromys duprasi natronensis and Gerbillus tarabuli, 
March 1903, collected by N. C. Rothschild and F. R. Henley. 
(22) Loemopsylla regis Rothsch. (1903). 
(PI. II, fig. 14; IV, fig. 10; V, fig. 7.) 
Pulex regis Rothschild (1903, p. 312, n. 1, t. 5, figs. 1, 3, 4, 7, 9, S. Arabia, off 
Meriones rex)-, Wagner (1903, p. 508); Baker (1905a, p. 143). 
The numerous long and slender bristles situated on the thorax and 
abdomen distinguish this insect markedly from all the others of the 
present group of species. 
Head. The rostrum in the </ is about as long as the maxillary 
palpus, reaching to the apex of the forecoxa, while in the $ it is longer 
than the palpus. The subapical row of bristles of the occiput contains 
on each side 6 to 8 bristles, there being also a long bristle above the 
centre of the antennal groove. 
Thorax. The tergites bear, on the two sides together, a row of 
18 or 19 bristles, there being some additional bristles on the back of the 
pro- and mesonotum in front of the row in the J 1 . The pleura of the 
prostemite is pointed posteriorly. The mesopleura bears 5 or 6 bristles. 
There are 2 bristles on the episternum of the metathorax and 13 to 15 
on the epimerum.
