PARASITOLOGV. 41 whose quarters are separated only by a partition, may get upon horses and cattle and cause temporary parasitism. Each parasite has its own host or hosts and will not live permanently upon another. Lice of Birds. The Large Hen Louse.—Menopon Biseriatum. This is the largest louse found upon the hen. It is about one-twelfth of an inch in length, light in color, with mouth parts arranged for mastication as illustrated in Fig. 10. The free extremities of the legs are provided with booklets which aid in holding on. The smaller variety of this genus, Menopon Pallidum, also has been studied, but is far less common in the United States. This louse is found on young and old Fiff. 10.—Menopon biseriatum (from a hen), greatly enlarged: a, head, which is provided with mouth parts; b, thorax provided with three pairs of legs; e, abdomen. The Turkey Louse.—Goniodes Stylifer. This louse is found on turkeys and is thicker than the one just described. Like it, the mouth parts are arranged for mastication. It is illustrated in Fig. 11. Lipeurus /nfuscatus. This is another louse that may infest chickens. A study of Fig. 13, shows its mouth parts and legs similar to the other lice. Its general shape is different. It is not so common as the large hen Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Kaupp, Benjamin Franklyn, 1874-.
