244 INSECTS AFFECTING DOMESTIC ANIMALS. 
One male and one larva. Burnett collection. From ‘“Perdix ameri- 
cana” (Oolinus virgimanus ). 
Nitzsch described the species from specimens taken from Caccabis rufa. 
Denny’s description would seem to have priority. He says common on 
the partridge (Perdix cinerea). 
Menopon tridens Nitzsch. 
Menopon tridens Burmeister, Handbuch, Vol. II, p. 440. 
Lemobothrum tridens Nitzsch, Ztschr. f. ges. Naturwissensch., 1866, Vol. XXVIII, p. 396 (vide

Menopon scopulacorne Denny, Monog., p. 221, Pl. XX VIIL, fig. 9. 
Menopon tridens Giebel, Epiz., p. 296, Pl. X VII, fig. 9. 
Menopon tridens Piaget, Les Pédic., p. 479, Pl. XX XIX, fig. 1. 
From coot (fulica americana), Ames, Iowa. Agrees closely with 
European description, except that abdomen appears broader than fig- 
ured. The peculiar structure running forward from occiput beneath 
seems to be characteristic. Also in Burnett collection. 
Recorded by Kellogg, who suggests three varieties to include the 
American forms, (New Mallophaga, p. 165).
