Maskell. — On a Parasite of the Penguin* 19 



I venture to suggest for this purpose the name Kermaphis. It is not so 

 far removed from the other as to be strange, and it would relieve entomology

 unless the differences noted in my description should be sufficient to raise it 

 to distinct specific rank.

Mr. A. Eeischek has collected at Dusky Sound a parasite of which the
