40 PROCEEDIXGS OF THE NATIONAL MUSEUM vol. los 



I am grateful to Dr. Henry W. Setzer of the Division of Mammals, 

 U. S. National Museum, who checked the host names used in this 

 paper. 



Genus Enderleinellus Fahrenholz 



Ilacmatopinus sutiiralis Osborn, U. S. Dep. Agr. Div. Ent. Bull, (old series) 



7, p. 27, fig. 15, 1891. 



Type data: "Plentiful" on Spermophilus franklini [Citellus 

 fmnklini] and S. 13-lineatus [Citellus tridecemlineatus] at Ames, Iowa. 



There is one slide with eight specimens of suturalis in the collection 

 with an Osborn label bearing the data "on Spermophilus 13-lineata, 

 4/24/84, Ames, Iowa." There is no determination on this label. On 

 the opposite side, in H. E. Swing's handwriting, is given: "Cyclo- 

 phthirus [Enderleinellus (crossed out)] suturalis (Osborn)," and a 

 sketch of the position of the specimens with one marked " cf holotype." 

 Osborn did not designate a holotype, and Ewing never published 

 a lectotype selection; therefore, Swing's label means nothing from a 

 nomenclatural standpoint. Although there is no species determination 

 by Osborn, it was Ewing's habit to rewrite type labels at times with 

 a new determination or a different generic combination. It is there- 

 fore accepted that Ewing recognized these to be the type series of 

 suUiralis, and the male designated by Ewing as "cf holotype" is here 

 selected as lectotype. 



Present status: Enderleinellus suturalis (Osborn), 1891. 



Genus Eulinognathus Cummings 



Eiilinognathus americanus Ewing, Journ. Washington Acad. Sci., vol. 13, No 



8, p. 149, 1923. 



Type data: USNM 23761. Holotype female from Ctenomys 

 brasiliensis (USNM 1939/3252) taken at Salade River, Paraguay. 

 Present status: As originally described. 



Genus Haematopinoides Osborn 



Haematopinoides squamosiis Osborn, U. S. Dep. Agr. Div. Ent. Bull, (old 

 series) 7, p. 28, fig. 16, 1891. 



Type data: Two females from pocket or pouched gopher, Geomys 

 bursarius, Ames, Iowa. 



There is in the collection a slide bearing data as above, a deter- 

 mination label in Osborn's handwriting, and containing two syntype 

 females. Further labels have been placed on the slide by H. E. 

 Ewing, the type No. 24137 is given and an accessory label gives a 

 sketch of the position of the two females with the one on the right 

 (next to the type label) labeled as lectotype. Ewing did not publish
