Nirmus vulgatus Kellogg.

Many specimens from numerous species of passerine 

 birds. This Nirmus must be treated like Docojjhorus 

 communis, in that we must group together under one 

 specific name forms rather variant (notably in length 

 and intensity of coloration), without being able as yet 

 to distinguish categorically these variations. Osborn's 

 pallidus (Insects Affecting Domestic Animals, 1896, 

 Bull. 5, N. S., Div. of Ent., U. S. Dept. Ag., p. 227). 

 from Zamelodia ludoviciana (Ames, Iowa) is probably 

 based on palely colored specimens of this species. The 

 name N. pallidus, by the way, is preoccupied (see 

 Piaget, Les Pediculines, 1880, p. 144). 



We refer to this species specimens from the Western 

 Blue Grosbeak, Gitiraca coerulea eurhyncha (4 birds, 

 California); the Western Lark Sparrow, Chondestes 

 grammacus strigatus (Ontario, California); the House 

 Finch, Carpodacus mexicanus frontalis (Ontario, Cali- 

 fornia); the California Towhee, Pipilo fuscus crissalis 

 (2 birds, Palo Alto, California); the Spurred Towhee, 

 Pipilo maculatus niegalonyx (Palo Alto, California); 

 the Golden-crowned Sparrow, Zonotrichia coronata (Palo, 

 Alto, California); the Lazuli Bunting, Passerina 

 amcena {Fsilo Alto, California); the Mountain Chickadee, 

 Parus gambeli (El Dorado county, California); the Cal- 

 ifornian Chickadee, Parus rufescens neglectus (Palo Alto, 

 California); the Western Bluebird, Sialia mexicana 

 occidentalis (Palo Alto, California); the Yellow War- 

 bler, Dendroica cestiva (Palo Alto, California); the 

 Lutescent Warbler, Helrninthophila celata lutescens (Palo 

 Alto, California) ; the Black-chinned Hummingbird,
