DESCRIPTION OF A NEW SPECIES OF 
SIPHONAPTERA FROM S. AMERICA 
Ss Va Ee 
Fon: N. €. ROTHSCHILD, ‘Mi A Fo LS, 
Ceratopsylla wolffsohni, spec. nov. 
HeEAD.—The anterior part of the head is shorter, and the 
second frontal flap slenderer, than in C. insignis. The head in 
other respects is similar to the head of that species. 
THORAX.—The pronotal como consists of from twenty-seven 
to twenty-nine teeth. The mesonotum has two slender bristle- 
like teeth on each side before the apex. On the matanotum there 
are laterally at the edge two short strongly chitinised teeth. 
Above these the segment is sinuate, so that the bristles of the 
subapical series become apical, resembling a comb as in insignis, 
The epimerum of the metathorax has two or three proximal 
hairs, a longer hair behind the stigma, another still longer placed 
farther down, and two more at the hinder edge. 
ABDOMEN.—The first abdominal tergite resembles the meta- 
notum in structure. The dorsal apical bristles, however, are still 
more tooth-like. On the other tergites the long bristles remain 
normal in position and length. The fourth, fifth and sixth 
tergites have only two small hairs in front of the row of bristles, 
The seventh tergite bears on each side one long apical bristle, 
which is situated on a cone, and has on each side of it a very 
small hair, 
The sternites of the fourth, fifth and sixth segments have in 
the male one hair and in the female four hairs on each side; the 
sternite of the seventh segment, however, bears a few more hairs 
in addition to these in both sexes. 
Lras.—The legs of this insect resemble those of 0. insignis.
