I. THREE NEW PARASITES OF THE TURKEY BUZZARD. 
Menopon alternatum u. sp. (Plate ir, Fig. i.) 
Broad, distinctly banded on the thorax and abdomen with fuscous. 
Female — Length, 1.97 to 2.09 mm.; head, length .32, width .288; thorax, 
length .448, width .40; abdomen, length 1.34, width 1.312 ; hind femur, 
.2S, .29; tibia, .25; antenna, .112. 
Head very broadly cordate, anterior border semi-circular, posterior border 
concave ; a few bristles along anterior margin and several short strong 
spines, and about three or four bristles at posterior angles. Antennal pits 
deep, antennae not or scarcely projecting beyond margin. Prothorax with 
prominent lateral angles and obtuse postero-lateral angles, posterior border 
slightly curved, bearing about eight bristles. Lateral angles of the meso- 
thorax sharp, a row of bristles across mesal portion same as metathorax, 
each having also diffuse fuscous band. Abdomen broadly ovate, lateral 
angles with several bristles of moderate length ; a broad transverse band on 
segments one to seven inclusive, the eighth having a rather broad diffuse 
fuscous area ; the bands are about equal in width to the interspaces, each 
segment has marginal series of bristles and about two irregular series anterior 
to the marginal, terminal segment with ciliate margin. 
Male: — Similar in form to the female, but abdomen apparently a little 
broader in proportion. The genital apparatus consists of a Y-shaped penis, 
behind which is a broad heavj' U-shaped structure, bordered at sides with 
slender lateral appendages, with almost thread like processes anteriorly and 
slightly curved processes posteriorly. 
Length, 1.82 to 1.84 mm. Head, length .272, width .416; thorax, length 
.43, width .27; abdomen, 1.04, 1.15; hind femur, .27, .24; hind tibia, .24; 
antenna, .112, .09. 
This species approaches the Menopon zonatutn Piag. occurring 
on the condor, Sarcorhamphus gryphus, but it is to be distin- 
guished from it by the wider head, the very uniform bands, the 
smaller size and by the genital apparatus. It was taken in con- 
siderable numbers from a turkey buzzard at Ames, Iowa, April 
21 , 1890 , and I have also received specimens from Prof. Lawrence 
Bruner, which were collected from the same species of bird at 
Lincoln, Nebraska. 
Colpocephaliim kelloggi 11. sp. (Plate 11, Fig. 2.) 
Slender, light yellow, with conspicuous black and fuscous or dark fuscous 
markings on head and borders of femora and tibiae, and lateral margins of 
segments one to seven of abdomen. Length, female, 1.84 mm.; male, 
1.42 mm. 
Head of usual form, lateral sinus deep, ocular and occipital spots very 
dark, partly black and connected by red brown bands. Antennae passin
