Nirmus parabolocybe Carriker, 1903, Univ. Nebraska Studies, vol. 3, 

 p. 137, pi. 2, fig. 3. Host: Tyrannus melancholicus=T. m. chloronotus 

 Berlepsch. Holotype 9 and allotype cf on slide 18 in U.S. Nat. Mus. 

 (68268). Present status: Briielia parabolocybe {C3xv\ktv). 



Nirmus pseudophaeus Carriker, 1903, Univ. Nebraska Studies, vol. 3, 

 p. 142, pi. 3, fig. 1. Host: Pezopetes capitalis Cabanis [trror = Buteo 

 swainsoni (Bonaparte)]. Holotype 9 on slide 21 in U.S. Nat. Mus. 

 (68271). Present status: synonym oi Degeeriella r. regalis (Giebel). 



Miss Clay has examined this type and has concluded that it is probably 

 a teneral specimen of D. regalis, found on Buteo swainsoni. A reexamina- 

 tion by the author and comparison with specimens of Degeeriella from 

 Buteo swainsoni, collected on the Volcano Irazu (locality where pseudophaeus 

 was taken) has confirmed the findings of Miss Clay. 



Nirmus rhamphasti Carriker, 1903, Univ. Nebraska Studies, vol. 3, p. 

 135, pi. 2, fig. 1. Host: Ramphastos tocard^R. swainsoni Gould, Holo- 

 type cf on slide 16 in U.S. Nat. Mus. (68267). 



In the 1952 Checklist of Mallophaga this species is listed as a Bruelia, 

 I cannot agree with this decision. It is impossible to determine its true 

 host, which certainly is not a Ramphastos. It resembles very much the 

 genus Sturnidoecus, both in the preantennary portion of the head and in 

 the male genitalia. Present status: Sturnidoecus ramphasti (Carriker). 



Nirmus trimarginis Carriker, 1902, Journ. New York Ent. Soc, vol. 10, 

 p. 222, pi. 20, fig. 2; pi. 21, fig. 5. Host: Certhia familiaris montanus=^C. 

 americana montana Ridgway. Holotype 9 and allotype cf on slide 6 

 in U.S. Nat. Mus. (68257). Note: The specimens presently on slide 6 

 are: 1 6^ adult, with good genitalia; 1 9 adult, in poor condition (due to 

 excessive clearing) ; and 3 teneral specimens, in poor condition. Present 

 status: Penenirmus trimarginis (Carriker). 



Nirmus truncatus magnocephalus Carriker, 1902, Journ. New York Ent. 

 Soc, vol. 10, p. 218, pi. 20, fig. 4, Host: Gallinago delicata (Ord) = 

 Capella gallinago delicata (Ord). Holotype 9 on slide 2 in Carriker coll. 

 U.S. Nat. Mus. (68253). Present status: Rhynomrmus magnocephalus 

 (Carriker). 



Nitzschia bruneri bruneri Carriker, 1903, Univ. Nebraska Studies, vol. 



3, no. 2, p. 177. Host: Aeronaules melanoleucus=A. s. saxatilis (Wood- 

 house). Holotype cf on slide 42 in U.S. Nat. Mus. (68292). Present

 Mus. (68293). Present status: Dennyus meridionalis {Ca.rriker) .
