Menacanthus cormutus (Schommer, 1913) 



Menopon comutum Schommer, 1913. Uber die Mallophagen: 64 and 71, 



pi. 7, fig. 29. 

 Type host: Chicken. 

 Menacanthus pallidulus - (Neumann, 1912) 



Menopon pallidulum Neumann, 1912. Arch. Parasit., 15: 361, figs. 



7-9. 

 Type host: Chicken. 



These 2 species from the chicken are mentioned together because 

 I have no data on either mallophagan. I did no active collecting of 

 ectoparasites of domestic birds and have collected neither of these 

 species. Both of these may have been taken on Old World Galliformes 

 and are much less common on chickens than Menacanthus stramineus 

 (Nitzsch, 1818). Emerson (1956) was the first to report M. comutus 

 from the United States. 



Menacanthus expansus (Osborn, 1896) 



Menopon expansum Osborn, 1896. Bull. U. S. Bur. Ent. (n. s.), 5: 



245, pi. 2, fig. j. 

 Type host: Dolychonyx oryzivorus (Linnaeus) — Bobolink. 



Osborn (1896) describes Menacanthus expansus as follows: 



Abdomen very broad, ovate. Head with sinuous margin 

 and very deeply emarginate occiput; orbital sinus 

 entirely covered; temporal lobes with 2 long bristles and 

 2 or 3 short hairs ; prothorax nearly as broad as head and 

 closely fitting into the occipital cavity, the lateral 

 angles in contact with temporal lobes; posterior margin 

 semicircular; metathorax short, rounded in front, with 2 

 bristles at the lateral angles; legs robust, femora very 

 large, irregularly set with short hairs; abdomen nearly 

 as broad as long, uniformly yellowish brown, margins of 

 segments above with a closely set series of hairs which 

 are longer at the lateral angles posteriorly, and the entire 

 ventral surface irregularly set with short hairs arising 

 from minute clear pustules.
