Docophorus quadraticeps n. sp. (Plate iii, fig. 5.) 



A male and a female taken from an American Coot, 

 Fulica americana (Monterey, California). This species 

 closely resembles kansensis, taken from an American 

 Eared Grebe, Colymbus nigricollis californicus (Law- 

 rence, Kansas). It differs from it by its larger size, the 

 more rotund abdomen, in the distinctly long acuminate 

 signature, and less markedly in the genital blotch. 



Description of female. Body, length 1.87 mm., width 

 .87 mm.; short golden brown with narrow dark margins 

 of thorax and anterior half of abdomen, and short trian- 

 gular abdominal blotches with few large pustulations.
