specimens cannot at present be definitely referred to this species with¬ 
out the males. 
Typhlopsylla nudata, sp. nov. 
Female. Length, 2 mm. This species is well distinguished by the almost entire 
absence of bristles on the body, coxce and femora. The labial palpi about equal, the 
maxillary palpi somewhat exceed, the fore coxm in length. Head otherwise normal, 
no vestige of eyes. Spines of tibiae few and rather weak, spines on fore and middle 
tarsi very weak, almost entirely absent on the former ; on hind tarsi long and slender, 
those on apex of first joint shorter than joint 2, but one of those on apex of joint 2 is 
much longer than joints 3 and 4 together, as in Pulex bruneri and allies. Middle 
and hind femora apparently deeply emarginate behind, before the apex, with an acute 
tooth before the emargination, a character not before noted in any American flea 
(Skuse mentions it for his Stephano circus). In fore tarsi joints 1, 2, and 3 are sub- 
equal in length and little longer than 4, while 5 equals 1 and 2 together. In middle 
tarsi joint 5 equals 3 and 4 together and is a little longer than I, the first four joints 
decreasing in length in this order, 1, 2, 3, 4- In hind tarsi joint 5 equals 3 and 4 
together and 1 equals 3, 4, and 5 together, while 2 is somewhat longer than 5. 
Described from two females taken by Mr. Hubbard from inner nest 
of Neotoma albigula , at Tucson, Ariz. This is the most interesting spe¬ 
cies of the genus yet found in North America. When the final disrupt¬ 
ing of Typhlopsylla comes this will fall in a genus by itself. 
Typhlopsylla charlottensis, sp. nov. 
Female. Length, 1.75 mm. Head with two oblique rows of spines, the lowest 
much the stronger. Bristles on apex of second antennal joint short. Labial palpi 
nearly equalling fore coxm. Pronotal comb of fourteen stout teeth. Dorsal segments 
with two rows of bristles, the principal row of five to seven long stout bristles on either 
side; ventral segments with three to four on a side. Fore coxae strongly bristled. 
Spines of fore and middle tarsi very weak, of hind tarsi strong. In fore tarsi joints 
1 and 2 are equal in length, 5 equals 3 and 4 together, and 4 is one-half of I. In 
middle tarsi 1 equals 2 and 3 together or 4 and 5 together, while 2 equals 5. In in 
tarsi spines all short, joint 2 is three-fourths of I, equals 3 and 4 together and is one- 
fourth longer than 5* 
Described from two females taken in a mouse nest atMassett, Queen 
Charlotte Islands, by Rev. J. H. Keen. It is nearest to atnericana, 
from which, however, it is very distinct as described above.
