b. — Acarina. (Ticks and Mites.) 



An undetermined species of tick [Ixodes) was recorded by Hurdis 

 (Rough Notes, p. 328) as found in large numbers on the leg of a 

 heifer. It was white and the size of a pea. Mr. Nathan Banks,* 

 1901, recorded a North American mite (Actineda agilis Banks), and 

 undetermined species of Mhyncholophus and Holostaspis as found in 

 our collection. A species known as the Eucharis-mite (Rhi- 

 zoglyphus echinopus) occurs on the diseased bulbs of the Easter Lily, 

 and is supposed to be one of the causes of the disease. A mite 



Mr. Banks has determined all the mites and spiders in our collections.
