94 THE EEPOET OF THE No. 36 



Family Eupodidae. 



Only three species have been found in Ontario. In chopped grain, under 

 bark of wood and under boards are the principal habitats of this family. They are 

 predaceous, soft-bodied, small mites with very long legs, and mandibles cheylate 

 like their relatives, the Cheyletidje. In many respects they are primitive in that 

 they possess characters similar to those of the spiders. 



Eupodes variabilis. Found abundant on barley seed in experimental grain 

 cellar. T. D. J., Guelph. 



Eupodes sp. Found under bark of Ironwood associated with other sp. of 

 mites. T. D. J., Guelph. 



Linopodes attenuipes Bks. Found under boards on College campus. T. D. J., 

 Guelph. 



Family Bdellid^. 



There are also three species of this family found in Ontario. Under bark 

 of balsam, crabapple, soft maple, apple, hard maple, in mangel seed, cavities of 

 stone and in ground spelt in Experimental grain cellar, are some of the places 

 inhabited by this family. They are closely related to the Eupodidae and Chev- 

 letidae in that they are predaceous with cheylate mouth parts and eephalothorax 

 partially distinct from the abdomen. They are red in colour with long, slender 

 legs and a well developed beak or rostrum.

 Soft Maple, Pyrus sp. In cavities in stone. T. D. J., Guelph. 



Bdella tenclla, Banks. Under bark of Hard Maple. In Mangel seed in the 

 Experimental grain cellar, T. D. J., Guelph. 



Bdella sp. Found in ground Spelt in Experimental grain cellar. T. D. J., 

 Guelph. 



Family Cheyletid.^. 



This family is more or less largely represented in the Ontario fauna, contain- 

 ing eight species, some parasitic and predaceous upon birds, rodents, and insects. 

 Other predaceous species may be found almost anywhere in search of mites and 

 other insects. They are characterized by having very large palpi and are dis- 

 tinguished from the previous families by the absence of the demarcation between 

 the eephalothorax and the abdomen. 



Myohia caudata, Banks. Abundant on little brown bat. T. D. J., Guelph. 



Myohia musculi, Derges. Found in abundance very closely attached to the 

 hairs of the house mouse. T. D. J., Guelph. 



' Cheyletes pyriformis, Banks. Found on larvs of Codling Moth in winter 

 nest. T. D. J., Guelph. 



Cheyletes longlpes, Banks. Several specimens found in gelatin culture in 

 Bacteriological laboratory., T. D. J., Guelph. 



. Cheyletes clavispinus, Banks. Several specimens were taken under bark of 

 lilac. T. D. J., Guelph. 



Cheyletes ferox. In hay, Ontario Agricultural College Barns. Mangel seed, 

 Experimental office. Grain in grain cellar. Barley seed, 0. A. C. barn. Ground 

 Spelt, Experimental Department. 



Cheyletielle Canadensis, Banks. Found on Bluebird, Sialia sialis. T. D. J., 

 Guelph. 



Sorergates sp. Parasite on house and field mouse in cavities or little cells
