Pulex corfidii, SPEC. NOV. 
?. Hea,d .—The front of the head bears a pointed tubercule 
directed backwards and projeeting f'rom a groove. There is a 
row of three bristles in front of the eye, the upper one standing 
at the antennal groove and the lower one behind the inaxillary 
palpus. In between these bristles there are two shorter ones. 
Above the eye there is a nuraber of short hairs. The genal 
edge bears a series of eight or nine bristles (which are nearly 
all broken oíF in my single specimen.) On the hinder part of 
the head there are a nuiuber of bristles along the antennal 
groove, and a complete subapical series of eight. The short 
hairs above the antennal stand in an almost regular row, but 
are not numerous. The head is punctured from the eye-bristles 
upwards, The rostruni is tnuch shorter than the forecoxa. The 
labial palpus consista of four segments only, the fourth segment 
being as long as the two preceding ones together. 
Tkorax .—d he prothorax bears two rows of bristles, and one 
or two bristles in front of them on tbe back. There is also a 
hair-like subapical dorsal spine on each side. The mesonotum 
bears tlnee rows of bristles and a subapical series of five hair- 
like spines. On the metanotum there are two rows of bristles. 
Ihe epimerurn of the mesonotum bears four bristles. The ineta- 
thoracieal epimerurn bears twelve bristles in two vertical slightly 
curved rows (7.5) and three short hairs beind the second row; the 
third bristle of the first row is nearer the base than the others. 
Abdomen —The abdominal tergites have two rows of bristles 
ths tirst tergite bearing two or three additional bristles on the 
back. The bristles in each row are very numerous, there being 
as man y as thirteen or fourteen in the second row on each side 
on the middle segments. The first tergite bears an apical comb 
ot ntteen spines on the two sides together. On the second tergite 
there are five spines, and on the third two. There is one long 
apical bristle on the seventh tergite. The stigma is small, and 
stands just in front of the anterior row of bristles and above the
