THE CANADIAN ENTOMOLOGIST, 197 



when I had no control of the Coleoptera, a somewhat cranky assistant 

 threw away labels by the bushel, without any consideration whether they 

 were types or in the handwriting of the most eminent entomologists, and 

 replaced the labels by numbers referring to a carelessly written catalogue. 

 A number of families of the Melsheimer and Ziegler collections shared 

 the fate of this destruction. • '■ 



NOTES ON MALLOPHAGA AND PEDICULID^. 



BY HERBERT OSBORN, AMES, IOWA. 

 [Read before the Entomological Club of the A. A. A. S.] 

 Identical or very similar species of these parasites occur on the closely 

 related birds and mammals of Europe and America, as is shown by the 

 following list of species collected at Ames : — 



EOCOPHORUS. ^ 



I?, platystoviits N. On Butco swainsonii, differs slightly from Denny's 

 description and figure. In Europe occurs on Buteo vulgaris. 



D. cursor- N. On Otus vulgaris var. Wilsonii, differs from Denny's 

 description in having lateral fasciae on seven segments, the eighth being 

 entirely dark, the ninth white ; foveolse arranged differently on the fasciae. 

 But these points agree well with Piaget's figures, so there may be a 

 discrepancy in Denny's work. In Europe occurs on Strix (Otus) 

 brachyotus, according to Piaget, and vulgaris and brachyotus, according 

 to Denny. 



D. testuditiarius D. On Numenius longirostris, agrees quite per- 

 fectly with Denny's description of specimens from Numenius arquaius, 

 also with Piaget's figure. 



Z>. cygni D. On Cygnus buccinator (?) Identical with descriptions 

 of European specimens from Cygnus mUsicus, according to Piaget, and 

 C. Bewickii, according to Denny. 



Specimens belonging to this genus were also taken from Shrike, Hairj 

 Woodpecker, Tern, Crow, Blackbird, Finch, House Martin and Coot, but 

 are as yet undetermined. 



XIRMUS. 



^V: fuscus N. On Buteo siuainsonii. Differs slightly from Denn/j^ 

 description and figures of specimens from Buteo vulgaris.
