Related to the Trichodectes infesting the larger mammals is a species which has been taken in immense numbers from the Pocket Gopher (Geomys hursarius), at Ames, Iowa. It was first taken in 1883 and since then has been collected from a great number of individuals, and I have also seen specimens taken from the western gopher, Thomomys, in a collection of parasites kindly loaned me by Mr. S.

It was first taken in 1883 and since then has been collected from a great number of individuals, and I have also seen specimens taken from the western gopher, Thomomys, in a collection of parasites kindly loaned me by Mr. S. E. Cassino. Body robust and rather hairy. Antennae very long, the basal segment enlarged, the head with a deep semicircular incision in front. The head is rather wider than long and the antenniP are situ- ated somewhat posterior to the middle and usually directed backward, very large and long, the joints nearly equal in length, but the basal are much enlarged in the male. Head with a deep semicircular incision on the otherwise semicircular anterior border, the posterior border slightly trilobed. Thorax short and broad ; suture distinct; abdomen ovate, tapering regularly and rapidly to the anal segment. Genital apparatus of male distinct. The hairs are distributed evenly over bolder of head and sides Fig. i2.—Trichodectes of body; four central segments of abdomen with transverse rows geomydis. (Original.) of stronger hairs or weak spines, and the lateral posterior angles of all segments but the first with long bristles. Length, 1 millimetre. The antennae in male and the deep frontal iucision separate this from any species known to me, and I think there is no question as to its being a distinct 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 United States.
