THE FLEAS OF NORTH AMERICA 101 



Myodopsylla diasi Costa Lima 



Myodopsylla diasi Costa Lima, 1938, Rev. Med. Cirurg. do Brasil 46 (2) : 182, 

 6 figs. 



Type host. — My oils velifer (Allen) (bat). 



Type locality. — S. Cristobal, Ecatepec, Mexico. 



Range. — Known only from Mexico. 



This species is most" closely allied to Myodopsylla collinsi Kohls, 

 with which it may possibly be identical. Since no specimens are at 

 hand for comparison with those of collinsi, it is best to regard it as 

 a separate species for the present. 



Myodopsylla gentilis Jordan and Rothschild 



Myodopsylla gentilis Jordan and Rothschild, 1921, Ectoparasites 1: 152, fig. 131. 



Type host.— "Bat." 



Type locality. — Okanagan Landing, British Columbia. 



Range. — Western part of the United States and Canada. 



The male terminalia are well illustrated in the original description 

 of this species. The seventh and eighth abdominal segments of the 

 female, however, are indicated as being the same as in Myodopsylla 

 insignia. 



Myodopsylla insignis (Rothschild) 



(Fig. 11, C) 



Ceratopsylla insignis Rothschild, 1903. Novitatea Zool. 10: 319. pi. 9, figs. 8-12. 

 Ceratopsyllus croslyi Baker, 1905, U. S. Natl. Mus. Proc. 29: 137. (New 



synonymy.) 

 Myodopsylla suoulata Chapin, 1919 ; Brooklyn Ent. Soc. Bui. 14: 55. 



Type host. — Myotis ludjugus (Lee.) (little brown bat). 



Type locality. — "Waterloo, Ontario, Canada. 



Range. — Eastern part of the United States and Canada. 



Through the kindness of Kobert Matheson, the writers have been 

 able to examine a single female specimen labeled "Ischnopsyllus 

 crosbyi Baker," belonging to Cornell University. This specimen ap- 

 peared to be the type of Baker's crosbyi. Our examination of it 

 revealed that crosbyi was identical with M. insignis (Rothschild). 



Jordan and Rothschild {51, p. 151), in 1921, placed Myodopsylla 

 subulata Chapin as a synonym of M. insignis (Rothschild), stating: 

 "An incorrectness in our original figure of the exopodite of M. in- 

 signis has unfortunately been the cause of the creation of a synonym." 

 This species has been redescribed and figured by I. Fox {25, pp. 105, 

 187).
