52 IXODOIDEA, OR TICKS, OF THE UNITED STATES. 



Ixodes cinctus Fabriciiis. 



" Reliqiiis magis oblongus. Caput ferriigineum. Sciitelliim tri- 

 angulum, ferriigineum, margine albo. Thorax et abdomen ferruginea, 

 antice cerea, sciitellum late alba. Pedes ferriiginei. Habitat in 

 America boreali Dom. v. Rohr. Miis. Dom. de Schestedt.'' [Either 

 Dermacentor variahUis Say or Amhiyomma maculatum Koch, and 

 probably the former.] 



SPECIES ERRONEOUSLY ACCREDITED TO THE UNITED STATES. 



Dermacentor reticulatus Fabricius. (PL X, fig. 10.) 



!^eiimann at first identified the forms now called D. oecidentaUs 

 and D. renKstus as this European species. As shown above, these 

 species are quite distinct, and there is no evidence that the true D. 

 reticulatus occurs in this country. 



Ixodes frontalis Panzer. 



As I have stated under Ixodes hrumieus, Neumann's identification 

 of /. frontalis was based on specimens of /. hrunneus. 



Ixodes inchoatus Neumann. 



Xeumann questionably recorded this from the United States, but 

 the specimens, as I have stated under /. marxi^ differ greatly from the 

 European /. inchoatus^ and with more material I have described 

 them as a new species — /. warxi. 



Haemaphysalis concinna Koch. 



As explained under Dermacentor nhjroUneatus^ the record of 11. 

 concinna is based on a misidentification of Packard's species.
