KELLOGG, MALLOPHAGA. 47 



sutural Spaces, but nearly or quite meeting on middle and Jience obliterating median 

 longitudinal line; posterior segment distinctly broadly truncate, even a little concave. 



Female, length 1.7 mm., width 0.43 mm., like the male except larger and with 

 dorsal transverse abdominal blotches not narrower on segments 6— S but covering 

 nearly the whole surface of each segment; posterior segment rather broadly roimded, 

 with very slight emargination.

Nirimis signatns Piaget. 



Numerous males and females from Becurvirostra avocetta, Himaniopus himan- 

 tojyus, Herodias alba and Phalacrocorax africanus. These speeimens all agree in differing 

 from Piaget's typical signatus (taken from Becurvirostra avocetta), by having the 

 genital blotches of the female curved instead of approximately straight.

Xinniis pilcus NiTzscn. 

 Numerous males and females (in Company with N. signatus) from Becurvirostra 

 avocetta.

Lipeurus afer n. sp. 



(PI. 7, fig. 5.) 



Males and females from Phalacrocorax africanus and Aj)lopelia larvata, a dove. 

 The speeimens from Aplopelia may be stragglers as the Lipeurus belongs to the group 

 clypeati peculiar to maritime birds, and especially well represented on cormorants. 

 The new species is quite distinct from any form heretofore recorded, especially in the 

 characters of the male. 



Male, length 2.2r. mm., Avidth O.ss mm., narrow-bodied with crenulate margins 

 and strongly marked kidney-shaped segmental lateral blotches. Head, length 0.47 

 mm., width, 0.34 mm., clypeus rounded in front with distinct signature and distinct 

 suture; antennae with first and second segments enlarged but much less than usual 

 in male Lipeuri and with no projecting process on any segment; third segment very 

 small; head brown with well marked antennal bands and eye spots; temporal mar- 

 gins without long hairs. Prothorax Square, brown with darker well-marked lateral 

 borders; no long hairs in postero-lateral angles. Metathorax a little longer and wider, 

 also quadrangular, but with slightiy projecting antero-lateral and postero-lateral 

 angles; four or five long hairs in circular uncolored space in postero-lateral angles; 

 posterior margin flatly concave on the abdomen; whole segment brown with well- 

 marked darker lateral borders. Abdomen long and slender, sides sub-parallel 

 as far back as segment 6, then tapering to tip; first segment narrower and larger 

 than second, single longish hair in postero-lateral angle of each segment; all segments 

 brown, with paler sutures especially laterally and on segments 3 to 7 and in less 

 degree on 8, distinct lateral shining blotches of curious auricular or reniform outline, 

 each blotch some distance mesad from the margin but connected with it by more
