A female and two immature specimens taken from a 

 Western Herring Gull, Larus occidentalis (Bay of Mon- 

 terey, California). This species was found by Nitzsch 

 on Larus ridibundus, and by Piaget on a Larus domi- 

 nicanus from Chili, a Larus crassirostris from China, and 

 a Larus ichthyaetus from the Volgas; a well distributed 

 form, surely. Piaget's figure omits the short hairs at the 

 anterior angles of the clypeus present apparently in all 

 nigropicti, and his description consistently with the draw- 

 ing refers to but three hairs on each side of the clypeus, 

 where there are really four. The specimen is much 

 larger (length 2.4 mm.) than Piaget's seem to have been, 

 the average length of his female specimens being 1.9 mm. 

 Description of young. Length, 1.5 mm., differing from 

 adult specially in incompleteness of markings and relative
