Menopon difficile Carriker, 1903, Univ. Nebraska Studies, vol. 3, no. 

 2, p. 188, pi. 8, fig. 1. Host: Biiarremon brunneinuchus=Atlapetes b. 

 brunneinuchus (La Fresnaye). Holotype cf and allotype 9 on slide 52 

 in U.S. Nat. Mus. (68302). Present status: Menacanthus difficile 

 (Carriker) . 



Menopon hirsutum Carriker, 1910, Ent. News, vol. 21, no. 2, p. 55, pi. 5, 

 fig. 3. Host: Dry abates pubescens=Dendrocopus pubescens medianus (Swain- 

 son) (this host is probably in error). The type was originally sent to 

 Mr. Shull at the Univ. Michigan Zool. Mus., but Dr. Emerson says it is 

 not now in the collection, and must be considered lost. It is most 

 certainly not a Menacanthus, but without a reexamination of the type it is 

 impossible to place it generically. 



Menopon laticorpus Carriker, 1903, Univ. Nebraska Studies, vol. 3, no. 

 2, p. 190, pi. 7, fig. 5. Host: Thamnophilus doliatus=T. d. intermedins 

 (Ridgway). Holotype 9 and allotype cf on slide 54 in U.S. Nat. 

 Mus. (68304). Present status: Machaerilaemus laticorpus (Carriker). 



Menopon macrocybe Carriker, 1903, Univ. Nebraska Studies, vol. 3, 

 no. 2, p. 181, pi. 7, fig. 2. Host: Buteo platypterus= B . p. platypterus 

 (Vieillot). Holotype 9 on slide 46 in U.S. Nat. Mus. (68296). Present 

 status: Kurodaia macrocybe (Carriker). 



Menopon ortalidis Carriker, 1903, Univ. Nebraska Studies, vol. 3, no. 

 2, p. 179, pi. 7, fig. 1. Host: Ortalis cinereiceps [error = 0. garrula frantzii 

 (Gabanis)]. Holotype d" on slide 45 in U.S. Nat. Mus. (68295). 

 Present status: Menacanthus ortalidis (Carriker). 



Menopon palloris Carriker, 1903, Univ. Nebraska Studies, vol. 3, no. 2, 

 p. 189, pi. 8, fig. 3. Host: Stelgidopteryx ruficollis uropygialis (Lawrence). 

 Holotype 9 and allotype cf on slide 55 in U.S. Nat. Mus. (68303). 

 Present status: Myrsidea palloris (Carriker). 



Menopon praecursor meridionale Carriker, 1903, Univ. Nebraska 

 Studies, vol. 3, no. 2, p. 182. Hosts: Melanerpes aurifrons hoffmanni 

 (Cabanis) and Odontophorus leucolaemus Salvin. Of the 3 cf cf and 3 

 99 listed in the original description, only 1 cf and 3 99 remain in the 

 collection. A careful comparison of these specimens with material from 

 other species of Odontophorus, and other woodpeckers, shows that they are 

 typical of the forms parasitic on Odontophorus, and not of the woodpecker 

 type. Evidently some error in the original mounting and labeling of 

 the specimens is accountable for this error. Holotype cf on slide 47 

 in U.S. Nat. Mus. (68297). Present status: Menacanthus meridionalis 

 (Carriker). 



Menopon stenodesmum Carriker, 1903, Univ. Nebraska Studies, vol. 3, 

 no. 2, p. 184, pi. 8, fig. 2. Host: Empidonax atriceps Salvin. Holotype 

 cf and ALLOTYPE 9 on slide 49 in U.S. Nat. Mus. (68299). Present 

 status: Aiyrsidea stenodesma (Carriker).
