THE CANADIAN ENTOMOLOGIST. Hi 



Pulex avium, Tschb. 



1880. Taschenberg, Die Flohe, p. 70. 



This species has quite an appalling synonymy. Dr. Taschenberg 

 records it from a great variety of birds, including the domestic fowl. I 

 have four specimens from Dr. Taschenberg, taken on Sturnus vulgaris in 

 Germany, and a single specimen taken at Ames, Iowa, by Prof, Herbert 

 Osborn — the host not given. It is recorded in Bull. 30 of the Texas 

 Exp. Sta. as "common; very troublesome last summer at Bryan, 'I'ex., on 

 chickens." This determination was undoubtedly an erroneous one, the 

 record probably referring to Sarcopsylla gallinacea. 



Pulex glacialis, Tschb. 



1880. Taschenberg, Die Flohe, p. 76. 



I have received specimens of this species from Mr. A. B. Cordley, 

 who took them on "cottontail rabbit," near the Grand Canon, in 

 Arizona. The type specimens were from Leptis glacialis, "collected at the 

 North Pole." 



Pulex Wickhami, n. sp. 



This species differs very widely in general appearance from any other 

 Pulex I have seen. The abdomen in the two females before me is some- 

 what swollen and suddenly and strongly rounded back of the thorax. The 

 swelling is not due to pregnancy, as the abdominal plates retain their 

 normal relative position. My specimens are from Sciuropterus volans, 

 and were collected at Iowa City, Iowa, by Mr. H. F. VVickham. 



Pulex Gillettei, n. sp. 



Closely related io/asciatus, though readily separated from it. Prof 

 C. P. Gillette took three specimens from Red Squirrel ( Sciurus cana- 

 densis) at Portland, Mich. 



Pulex fasciat7is, Bosc. 



1801. Bosc d' Antic, Bull, des Sci. par la Soc. I'hilomat. II. , p. 156, 

 No. 44. 



I have seen nothing among the specimens examined that I could 

 refer to this species as it is described and figured by Taschenberg. It 

 was originally described from Myoxus nitela and Talpa europea- 

 Kolenati found it on Cricetus frumentarius. Taschenberg records it 

 from Myoxus, Mus tnusculus, Mus decumans, and Canis lagopus, in 

 Europe, and without giving host, from Mammoth Cave, in Kentucky.
