 short ones along the margin of the segment; two brown 

 flecks on front margin, and the rounding anterior angles

 and very narrow marginal lines ; front margins of femora 

 of middle and hind legs with four or five subequal prom- 

 inent hairs and several very short ones. 



Abdomen, parallel-sided for anterior half and then 

 gradually tapering posteriorly; no marginal constrictions 

 between segments; but one or two long hairs in each 

 posterior angle; last segment with one strong long hair

A single specimen from an American Coot, Fulica 

 americana (Monterey, California). The previouslv 

 taken specimens have been found on Fulica atra, also 

 probably one occurrence on Podicefts rubricollis. The 

 descriptions vary somewhat and are incomplete, and 

 Giebel's figure shows strange markings of head and tho- 

 rax, but the large size and dark coloration of the entire 

 body sufficiently identify the species. Giebel's measure- 

 ments are far under those of my specimen, which are: 

 body, length 8 mm., width 1.9 mm.; head, length 1.4 

 mm., width 1.17 mm.
