bees and ants ; some Gamasids feed upon the dead bodies of the 

 latter. A species of Lcdaps has been observed to jump upon an 

 ant and ride about on it, without in any way disconcerting the 

 Formicid. Each species of mite is said to prefer to live with a 

 particular species of ant, although several kinds have been found 

 in one nest. When the ants quit the nest the mites disappear 

 also. Protonymphs have been collected from plants, and deuto- 

 nymphs and tritonymphs from meals — flour, etc. — and houses. 



Genus Cel^nopsis, Kram. 



A number of mites from various parts of the world, 

 including one from Australia, have been associated with Koch's 

 o-enus Ceke.no, which was founded in 1835. This name, however, 

 cannot stand for the Arachnida, as it was preoccupied for the 

 Mammalia, Leach having in 1822 proposed Gekeiio for a bat. 

 For the present, therefore, I suggest that as CeUeno, Koch, has to 

 sink into the ranks of synonymy, Kramer's Celcejiopsis be used 

 instead.
