2nd segment rarely with a short appendage; 3rd segment usually pedicu- 

 lated and goblet-shaped, receiving the spherical, ovoid or cylindrical 

 4th segment which is invariably the largest. Prothorax distinct, smaller 

 than head; mesothorax fused with metathorax. Legs long, ventral surface 

 of posterior femur and abdominal sternite IV with thick brushes of small 

 setae. Sternite V may have indefinite brushes of 3 to 6 setae. Abdomen 

 with internal pleural thickening. Individuals interested in this genus 

 should consult the works of Ferris (1924) , who revised the family 

 Menoponidae, and Emerson (1954a), who reviewed the known species of 

 the genus. 



The only member of this genus found in New England is Menopon 

 gallinae (Linnaeus), the "shaft louse" of chickens. Collections of 

 this species are numerous.
