132 THE CANADIAN ENTOMOLOGIST. 



on joint 2 of antennae longer than joint 3 ; pronotal comb of 16 

 spines; in anterior tarsi joint i equals 3 and is shorter than 2, 

 5 long as I and 2 together, and nearly three times 4 ; in middle 

 tarsi joint 5 one-fifth longer than 2 ; in hind tarsi joint 5 less 

 than 3 and 4 together, but more than one-half of i, 2 twice 

 4, but less than 4 and 5 together ; colour, light brown, darker

 Pulex hii'sutiis, n. sp. 



This flea, with its long and abundant spines and bristles, presents a 

 very unustial appearance. It was collected on the Prairie \)og( Cynomys 

 ludovicianus), at Stove Prairie, Larimer Co., Colo., by Prof C. P. Gillette. 

 Pulex B rimer i^ n. sp. 



I have received specimens of this species taken on Spermophilus ij, 

 lineatiis and S. F? ajikiini, at Lincoln, Neb., by Prof Lawrence Bruner, 

 and others, taken on the first named host by Prof Herbert Osborn. I 

 have also taken specimens from the same host at Fort Collins. 

 Pulex sciurorum, Bouche. 



1835. Bouche, Nov. Act. Acad. Leop., Carol., XVIL, i., p. 506. 

 I have specimens of this species from Dr. Taschenberg, taken on 

 Sciurus vulgaris in Germany. It has also been recorded from Rhinolo- 

 phus ferrum-equinum. I do not know that it occurs in North America. 



Pulex metis. Walker. 



1856. Walker, Insecta Britt. Diptera , IIL, p. 5. 



This very large and long flea has been recorded from Meles taxus 

 and Canis vulpes. I have seen no fleas from either badger or fox 

 collected in North America, 



Pulex longispinus, n. sp. 



I have received specimens of this flea taken on Fremont's Chickaree 

 at Georgetown, Colo., with P. coloradensis. It seems likely that there is 

 an error in the data fcr either this species or P. coloradensis- It is not a 

 usual occurrence for two species of fleas to be found living together on a 

 single wild animal. These species are totally distinct. 



Pulex monta?ius, n. sp. 



My specimens of this flea were taken from the large Mountain 

 Grey-Squirrel (Sciuriis Abertil), in the foothills west of Fort Collins, by 

 Prof. J. D. Stannard.
