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, coxae and femora. The labial palpi about equal, the 

 maxillary palpi somewhat exceed, the fore coxae 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 Stephanocirais). 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 I 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 coxae. 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 segmeats 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 

 I and 2 are equal in length, 5 equals 3 and 4 together, and 4 is one-half of I. In 

 middle tarsi I equals 2 and 3 together or 4 and 5 together, while 2 equals 5. In hind 

 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 at Massett, Queen 

 Charlotte Islands, by Rev. J. H. Keen. It is nearest to americana, 

 from which, however, it is very distinct as described above.
