Description from twelve specimens in the collection of Pro¬ 
fessor Jas. S. Hine, of Ohio State University, taken by him from

Fig. 1. G, Physostomum invadens Kell., female from Dendroica 
pennsylvanica. H, Menopon eolaptis, female from Colaptes auratus.

Taken from Phalacrocorax dilophus by Professor Jas. S. 
Hine at Columbus, O. Professor Kellogg, Kellogg and Chap¬ 
man, Mallophaga from Birds of California, New Mallophaga III, 
1899, describes the variety incompositum from Phalacrocorax

Pediculines, 1880, p. 608, Supplement, 1885, p. 137, Plate XV,

Two specimens taken from Chaetura pelagica by Professor 
Jas S. Hine, at Columbus, O. In Kellogg and Chapman, New 
Mallophaga III, p. 133 et seq., reference is made to the seemingly 
inadequate ground for the establishment of the Genus Eureum, 
and also to the suspicion on the part of Piaget that the forms so
