Illustrative vignette (elephant). Texture of skin hard and chitonous, antennae lenticular five-jointed, head wi'h a long slender rostrum like that of an Api'on but less curved, body ovate and convex on the back, scutellum broad and narrow, tarsi with only one claw. Colour reddish madder brown, smooth and shining, impunctate. Infests the Genus H.^matopinus {Leach). Head not rostrate ; legs thick. This is the principal genus that is parasitic on mammals. With the exception of the preceding insect takea on the elephant, it includes all the blood-sucking lice that attack mammals other than man.

They leave the body much sooner after death than the mallo- phagous specie?, vhich adhere to the feathers or fur for 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 Murray, Andrew, 1812-1878.
