This is the "brown chicken louse" common throughout the United 

 States. It will be discussed together with the following species, G. 

 gigas (Taschenberg, 1879) which is also a parasite of the chicken.

Chicken. 



G. gigas is known as the "large chicken louse" and is common on the 

 domestic chicken. G. dissimilis and G. gigas may be distinguished by 

 the following key: 



Antennae similar in the 2 sexes . Three long setae 

 on each temple G. gigas 



Antennae sexually dimorphic. Two long setae on 

 each temple G. dissimilis 



No attempt was made to collect Mallophaga from the chicken during 

 the course of this study. 



INCIDIFRONS 



Incidifrons Ewing, 1929. Manual External Parasites: 111 and 189. 



Type species: Philopterus pertusus Burmeister, 1838 (A synonym 

 of Pediculus fulicae Linnaeus, 1758). 



Head large, with conspicuous rounded temples and prominent forehead 

 with slightly concave sides. Anterior margin of head deeply incised or 

 notched, the notch being flanked by converging, hyaline flaps. Dorsal 

 anterior plate conspicuous, undivided. Trabeculae large. Antennae 

 short and similar in the 2 sexes. Pterothorax broader than long, sides 

 divergent, posterior margin either outwardly rounded or angulate. 

 Abdomen stout, with 9 segments, the last being very small; abdominal 

 spiracles conspicuous, 6 pairs. Members of the genus Incidifrons are 

 ectoparasitic on birds of the order Gruiformes.
