all agree in referring the figure by Kedi to this species, Linnaeus places 
it under his Pediculus caponis, which is equivalent to Lipeurus vari- 
abilis N. 
The annoyance that this one species causes poultry 
is probably equal to that of all the other species com- 
bined, for it occurs in great abundance and almost 
every fowl examined will be found infested. Then, too, 
it passes readily to other species of birds, and many in- 
stances are recorded where horses kept near henroosts 
have been very seriously troubled by them. Some of 
these accounts seem hardly credible taken in connec- 
tion with the habits of the insect, and we are inclined 
to think that the worst cases, at least, may have been FlG zi.-Menopon 
due to the presence of itch mites on the poultry and pallidum. (After 
the migration of them to the horses, though in such case Denny) - 
we should expect the fowls themselves to show more serious injury. It 
is, at any rate, important to keep lousy chickens away from horses. 
The louse is pretty easily distinguished from other common species 
infesting the hen by its light color and its great activity, running with 
great celerity among the feathers and from them upon the hands of 
persons holding fowls. It is from 1 to 1£ millietres in length, rather 
slender, and of a light straw-yellow color. 
Eemedies for this species must aim to reach the hiding places of the 
lice on the roosts and in the cracks of the walls of the henhouse as well 
as to destroy those on the fowl. Thorough fumigation and white wash- 
ing, with careful attention to cleanliness, will do much to keep them in 
check. Pyrethrum, kerosene, etc., may be used direct upon the fowls, 
and if they are liberally supplied with ashes and road dust they will 
do much to protect themselves. 
(Menopon biseriatum Piaget ; Menopon stramineum Xitzsch.) 
Under the above name Piaget describes a species of louse taken from 
the Gallopha8is cuvieri, and which he speaks of as occurring also on 
the domestic fowl, the pheasant, and other birds. He Bays "Sur mi- 
Oallophasis [Euplocamus) cuvieri j'ai retrouve le ineine parasite sur un 
Gallus domesticus, sur un Phasianus colchicus, sur an Pavo spici/erus 
male et femelle en assez grand nombre et dernierement anssi sur une 
Meleagris gallopavo. II se rapproche evidemment du stramineum de 
N., promenant d'une Meleagris gallopavo, doinmage que la diagnose de 
Giebel (Epiz., p, 291) soit trop vague pour ^identifier, mais plus en- 
core du Pediculus Mcleagridis de Panzer (51 f. 20). Peut-etie est-ce le 
parasite de Schrank No. 1019, recueilli sur le meme oiseau." 
It seems very probable that the description of Panzer, Nitzsch, Giebel. 
and Piaget all apply to the same insect, and if such is the case it would
