xxxvi, (1. 143), also the extraordinary disproportion in size and appearance between 

 the male and female moths. The larva is between 4 and 5 inches long ; excessively 

 shaggy ; black or browu-black, covered with tufts of similar hairs; along the sides 

 arc larger I ufts of hair — yellow in the male, white in the female — and depressed so 

 as to form long fringes ; similar but sliorter tufts projecting over the face, and 

 much larger tufts, curved forward, on each side of the head.]

NEW SPEICIBS OF SIPHONAPTERA FROM EGYPT AND THE 

 SOUDAN (WITH TWO PLATES). 



By TllK HUN. N. CHAKLES ItOTHSCHlLD, M.A., F.L.S. 



Ill the present paper six new species are named. The first five 

 are all described from specimens taken in Egypt and the 8oudan by 

 the author and Mr. A. ¥. R. Wollaston in 1901. For the last-named 

 species, Pidejc WUherbyi, the author is indebted to Mr. Harry F. 

 Witherby, who secured it from Eririacius albivcntris near Gebel xluli, 

 in May, 19UU. The author and Mr. Wolhiston, however, subsequently 

 found it near JShendi (see p. 87). The features of the present 

 article are the first mention of the very curious developments of the 

 male jjosterior segments in the new species of the genus Pulex, and 

 also the first record of a comb-like organ appearing on the meta- 

 thoracic epimera of a flea. Further references to the hosts from 

 which these specimens were secured is given in " Novitates Zoologicse 

 vol. viii, pp. 3t)7-l'Ul (19U1).

The head is strongly rounded in front, the frontal outline (side-view) forming 

 almost a semicircle. The ante-oral liaps are longer than in any other member of 

 the genus tliat has come under our notice. The second flap being rather longer 

 than half the vertical diameter of the head, measured from just in front of the 

 antennal groove. The anterior portion of the head bears a series of short hairs 

 parallel to the frontal outline. The more dorsal hairs of this row gradually increase 

 in length and become more strongly chitinised, the last six being spine-like. Below 

 these spine-like hairs arc a few more of the same size. The genal process is very 

 long and slender, being strongly chitinised. The post antennal portion of the head 

 is densely covered with fine hairs on its dorsal surface. This portion also bears a 

 row of hairs near the hinder edge, and one long hair towards the centre. The 

 prothoraic comb consists of eighteen teetii. The mesonotum is clothed above with 

 numerous hairs, and bears on eacli side two short spine-like projections. The 

 metanotum is somewhat shorter than the mesonotum, appearing in side-view to be 

 acuminate in shape, and bearing at the apex on each side a short spine. The
