Pulex cocyti. SPEC. NOV. 
This is a small and very palé species. 
Head .—The head is nearly evenly rounded in the $, while 
in the $ the dorsal line of the occiput is nearly horizontal. The 
oeciput is two and a half times as long again as the frons in 
the $. There is a row of threehristles in front of the eye. The 
occiput bears a regular series of long and short hairs, the most 
ventral one being the longest. The interspace between this 
bristle and the next long one is a little wider than the interspace 
between the second and third. Above the antennal groove there 
are two or three more hairs, but there are no further hairs on 
the sities. In the $ the dorsal depression of the occiput is covered 
with numerous very fine hairs. Above the antennal groove 
there is a regular row of short and fine spine-like hairs which 
stand cióse together. This row extends in the $ nearly to the 
groove in which the antenna is inserted, while in the$ the 
row is much shorter, being restricted to the hinder third of the 
occiput. The second segment of the maxillary palpus is twice 
as longas the third and one-third shorter than the fourth. The 
labial palpus eonsists of five segments, the second and third 
being the shortest. 
Thorax .—The pronotum bears one row of short bristles and 
some additional ones on the back. Between the row of long 
bristles of the mesonotum and the hinder edge there is a row of 
about nine long and very thin hair-like spines. The epimerum 
of the mesothorax bears four bristles, two in the rniddle and 
two behind. The metanotum bears a row of long bristles, and 
an abbreviated row of shorter ones in front of it, and some 
additional hairs on the back. The epimerum of the metathorax 
bears two or three hairs in front and two or three from the 
■stigina downwards, the uppermost anterior bristle being on a 
leve] with the stigma. 
Abdomen .—The abdominal tergites bear each one row of 
long bristles, with a rather long thin hair between each two, as 
on the thoracic tergites. In the $ there is on all tergites an
