LIPEURUS MIRICEPS sp. nov. 



(PI. XXX, fig. 4.) 



One male from Geospiza fuliginosa from Albemarle. This 

 Lipeurus is more like L. conjidens Kellogg, irova Diomedea nigripes 

 from Alaska, than like any other described form, but is smaller and 

 distinctly different in markings. The specimen is probably a normal 

 straggler on Geospiza from some maritime bird, perhaps an albatross, 

 rather than the representative of a species peculiar to Geospiza. 



Male. — Body, length 3.5 mm., width. 83 mm. ; elongate, whitish 

 with sharply defined, black markings, the lateral abdominal bands con- 

 sisting of segmental elongate blotches. Head, length .85 mm., 

 width .31 mm.; not tapering, elongate with subparallel sides ; front 

 parabolic with clypeal margin uncolored ; two marginal hairs in 

 front of the sutui^e, one in suture and one hair and two prickles behind
