REVISION OF THE SARCOPSYLLIDAE

$. The eight tergite (PI. I, Fig. 12) is rather broadly sinuate at the apex. It 
bears about six bristles on the outside, arranged in a halfring, and a row of five or 
six on the inner side. The stylet (sty) is not quite twice as long as it is broad. It is 
cylindrical and bears three bristles at the apex, one being long and the others short.

4. Echidnophaga aethiops, spec. nov. 
We have only one % of this species, which is allied to, but perfectly distinct 
from, E. gallinaceus. 
Head. — The Irons is not angulate, the head being almost evenly and very feebly 
rounded from the hinder edge to the mouth. The occiput is dorsally less than half 
the length of the frons. There are two long bristles above the antennal groove on 
the occiput. The oral edge measured from the ventral frontal corner ol the head to 
the apex of the ventral genal process is longer than the genal edge measured from 
the base of this process to the apex of the posterior (horizontal) genal process. The 
mandibles are shorter and narrower than in E. gallinaceus. The maxillary palpus is 
quite different, the first segment being a little shorter than the last, and the second 
being hardly more than half the length of the fourth, not being longer than the third. 
The hinder edge of the occiput does not bear a lateral lobe. 
Thorax. — The metathoracical episternum bears an irregular series of five or six 
bristles, and has in addition a small bristle in front of the stigma. 
Abdomen. — The bristles of the proximal tergites are less strongly chitinized than 
in E. gallinaceus %. There is a row of six bristles on the seventh tergite on the two 
sides together, the dorsal bristles being small. The subapical bristle of this segment 
stands much closer to the edge than in gallinaceus. The stigmatical cavities are much 
smaller than in the % of that species, their diameter being about half the length or 
that of the stigmatical cavity of the metathoracical epimerum. 
Legs. — The hind coxa bears a patch of about sixteen spine-like bristles, besides 
some longer hairs. There are only two bristles on the hind femur instead of a row. 
The fifth tarsal segment is shorter than in E. gallinaceus, and the basal projection of 
the claw more distinct. The measurements of the mid and hind tarsi are as 
follows : —
