Description of the male. Body, length 1,72 mm., 

 width .36 mm.; head, length .43 mm., width .37 mm.; 

 head like female, perhaps a little narrower, compara- 

 tively, behind; antennae with segments 1 and 2 rather 

 large, subequal, segments 3 and 4 very small, subequal, 

 and segment 5 as long as 3 and 4 together, no distinct 

 appendage; metathorax with sides nearly parallel, not 

 plainly divergent as in female; abdomen slender, sides 

 subparallel, ground color pale golden with wide whitish 

 transverse sutural bands and prominent brown, shining 

 subcircular lateral blotches not touching the narrow, 

 inconspicuous blackish lateral bands; last segment 

 truncate behind, with a group of four prominent hairs 

 on each lateral half of the margin. 



Lipeurus forficulatus Nitzsch. (See Kellogg, New Mal- 

 lophaga, I, 1896, p. 129, pi. ix, figs. 3, 4, 5 and 6). 



Specimens from a Calif ornian Brown Pelican, Pele- 

 canus californicus (Bay of Monterey, California), 

 Taken previously by Kellogg from same host species, 

 same locality; and from the White Pelican, P. erythro- 

 rhynchus (Lawrence, Kansas.) 



Lipeurus squalidus Nitzsch. (See Kellogg, New Mallo- 

 phaga, I, 1896, p. 132, pi. x, figs. 6 and 7.) 



Six specimens from a Shoveller, Spatula clypeata 

 (Palo Alto, California). These specimens resemble very 

 much those specimens which Kellogg collected from 

 Merganser serrator (see New Mallophaga, I, p. 130, pi, 

 X, fig. 1). In fact, we fail to make out any good dis- 

 tinction between the species temporalis Nitzsch (found on 

 the Mergansers) and the species squalidiis of Anas and 

 allied ducks.
