I. THREE NEW PARASITES OF THE TURKEY BUZZARD. 



]\Icnopon alternatum 11. sp. (Plate 11, 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 .44S, width .40; abdomen, length 1.34, width 1.312 ; hind femur, 

 .28, .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, Ijearing 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. 



INIale; — 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 heavy 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. 



Thi.s .species approaches the Menopoii zonatttin Piag. occtirring 

 on the condor, Sarcorhaniphtis gryphtis, btit it i.s to be distin- 

 gtiished from it by the wider head, the ver}" uniform bands, the 

 smaller size and b}' the genital apparattis. It was taken in con- 

 siderable numbers from a turke}" bttzzard 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 

 lyincoln, Nebraska. 



Colpocephahim kelloggi n. sp. (Plate 11, Fig. 2.) 



Slender, light yellow, with conspicuous black and fuscous or dark fuscous 

 markings on head and borders of femora and tibiie, 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 h\ red brown bands. Antennte passin
