REVISION OF THE SARCOPSYLLIDAE 49 
Modified Segments. — $. These segments are very different from those of the 
other species of Echidnophaga. The eighth stern ite is very large and is apically pro- 
duced into an acute process (PI. II, Fig. 19, viii. st). The internal part of the ninth 
tergite is long (ix. t). The manubrium (M) is widened at the apex. The hairy 
process (P 1 ) of the clasper is very large, gradually widening towards the apex, which is 
rounded. This process is about as long as the head, measured from the ventral 
frontal corner to the apex of the posterior (horizontal) genal process. The second 
process of the clasper (P 2 ) is peculiar, being produced dorsally into a tooth. The 
finger (F) is long and slender. The ninth sternite (ix. st) is distally dilated into a 
rather broad lobe. 
$. The apex of the eighth tergite (PI. II, Fig. 1 3) is bisinuate. It bears a row of 
short stout bristles on the outer side and a similar row of thinner ones on the inner 
side. There are on the outer side also some bristles at the ventral edge and a variable 
number on the lateral surface. The stylet (sty) is less than twice as long as it is 
broad. It is cylindrical and bears one long bristle and two short ones.

Head. — The frons is angulate in both sexes at one-third the way from the ventral 
frontal corner to the antennal groove, the angle being emphasized in the fj? by the 
frons being more deeply impressed than in the # just behind the angle, the latter 
therefore projecting usually as an acute tubercle. The brislles on the head are all 
short, except the eye-bristle and the bristle which is situated near the oral edge. The 
small hairs on the back of the frontal part of the head are longer than is usually the 
case in this genus. The ventral genal protection is not curved backwards. The edge 
of the occiput is simple in both sexes. The occiput is in the dorsal line half the 
length of the frons. The mandibles are very broad, being near the base in the $ 
more than twice, and in the $ about four times the width of the maxillary palpi. The 
first segment of the latter is a little longer than the last, especially in the the pro- 
portional lengths of segments being 20 to 24, 16 to 19, 11 to 14, 18 to 21. 
Thorax. — The pronotum bears four small bristles on each side, the ventral one 
being the longest, the mesonotum has two still smaller ones, and the metanotum one 
or two minute ones on the back. The metanotum is dorsally longer than the meso- 
notum. The apical projection of the prosternite is very short and obtuse. The
