NEW MALLOPHAGA. 483; 



Docophorus californiensis n. sp. (Plate lxvi, fig. 6.) 



Numerous specimens, male, female, and young from 

 several specimens of the California Woodpecker, Mela- 

 nerfes formicivorous bairdi (Palo Alto, California) . An- 

 other member of the angustifrontes, of same size and out- 

 line as the last, but with strong and characteristic mark- 

 ings. It is very like D. superciliosus N. (Giebel, Insecta 

 Epizoa, p. 94, pi. x, fig. 3), the type of the group taken 

 by Nitzsch, Denny, and Piaget from Picas major and P. 

 viridis. It appears to differ from sufercilzosus in the pos- 

 session of hairs in the posterior angles of the prothorax, 

 in the absence of numerous hairs on dorsal surface of ab- 

 domen, and in the sharper and more pronounced mark- 

 ings.

 width .62 mm.; pale smoky brown, with dark brown to 

 black bands and blotches. 



Head, length .53 mm., width .47 mm.; triangular, 

 forehead tapering, and clypeal front narrow and slightly 

 concave, with two hairs in the anterior angles, one shorter 

 one between angle and suture, a longer one just in front 

 of suture, and two rather long ones in front of trabecular; 

 eye prominent, with long hair; trabecular acute, reaching 

 slightly beyond end of segment 1 of antennae; temporal 

 margins with two long hairs and a prickle ; occipital mar- 

 gin sinuous, bare; clypeus paler than rest of forehead 

 and hind head; signature pale but distinct; suture dis- 

 tinct; antennal bands, ocular blotch, and anterior tempo- 

 ral border blackish brown ; temporal regions and rest of 

 head, excepting clypeus and that part of hind head between 

 the occipital bands, dark brown; oesophageal sclerite dis- 

 tinct.
