Mallophaga from the Birds of Laysan Island. 



BY VERNON L. KELLOGG AND JOHN H. PAINE, Stanford 



University, Cal. 



A small lot of Mallophaga collected from maritime birds by 

 Prof. John O. Snyder and Dr. Walter K. Fisher, on the Stan- 

 ford-Albatross Expedition of 1902, to the Hawaiian and adja- 

 cent islands. The specimens were collected immediately after 

 the birds were shot and while the Mallophaga were still alive. 

 In the lot are represented eleven species, one of which being 

 new, is described and figured herewith. 



Docophorus snyderi n. sp. (Fig?, i and 2). 



Six specimens from a tern, Sterna lunata, (Laysan Isl.). 

 This species greatly resembles D. melano- 

 cephalus, but may be easily distinguished 

 from it by the rounded but distinct me- 

 dian angle of the posterior margin of 

 the prothorax and by the concave clypeal 

 front. 



Female. Length 1.7 mm., width .64 mm. 

 head, length .6 mm, width .58 mm ; clypeus nar- 

 rower than in melanocepJialus, concave, trans- 

 parent in front of signature with a short hair 

 arising near the termination of the colored 

 lateral band and reaching to the margin ; an- 

 other hair arising a little posterior to the 

 anterior angles of the signature and within 

 the signature ; two more clypeal hairs at about 

 the middle of the lateral margin, one marginal * 

 and the other arising just within the margin; 

 and still another very minute hair in front of the suture; trabeculae 

 narrow, extending to about the middle of the second joint of the 



antenna?, temporal margins broadly rounded; two 

 hairs, one of which is very short, arising from 

 the eye; three more on the temporal margin, the 

 anterior two being close together, of which two 

 the posterior one is minute. Prothorax with 

 middle of posterior margin strongly though 

 f 7* WJ * i)i T 1 | roundly angled; a single long hair arises at the 

 posterior lateral angles. Metathorax with pos- 

 terior margin nearly parallel to that of the pro- 

 thorax though the angle is slightly more acute; a row of about sixteen
