Parasitism, C. W. Stiles {Fvoc. Ent. Soe. Washington., 3 {1894), No, 

 l,pp. J-!)). — A general discussion of parasitism from the standpoint of 

 the belminthologist, Tbe autlior makes the following divisions: A, 

 based upon symbiosis and food — (1) mutuallsts; (13) cominensalists; (3) 

 true parasites; (4) pseudo-[)arasites; and (5) spurious parasites. B, 

 based upon position — (1) ectoparasites; (U) endoparasites. C, based 

 upon the animals and plants — (1) phytopai'asites, [a) in or upon auimals, 

 {h) in or ujjon j)lants; (!') zoiiparasites, {(i) in or upon animals, (b) in or 

 upon plants. D, based upon time — (1) temporary parasites; and (2) 

 stationary parasites, including (a) periodical parasites and {b) perma- 

 nent parasites. E, based upon adaptation or necessity — (1) facultative 

 parasites; (i') obligatory parasites. F, based upon the number of 

 hosts — (1) monoxenous ])arasites; (2) heteroxenous parasites. Connect- 

 ing links exist between various divisions. — o. w. stiles. 



A ne'W human parasite, K. Moniez [Rev. Biol. d. Nord Fr(()ice, 6 

 [1894), No. 11, pp. 119-434). — Description, life history, and anatomy of 

 Tydeius molestus, a new species of acarid which attacks man in Belgium. 

 During 1888 this mite became extremely abundant in the gardens of a 

 large property situated not far from Ath, in Belgium, where it had 

 been noticed in smaller numbers for 25 years. It is suspected that it 

 was introduced with guano from Peru. In passing through the gar- 

 dens and brushing against the vegetation one becomes covered with 

 the mites, which produce an irritation f^ii^'l^i' ^^ ih?d, of the larval 

 Trombidiums, commonly called jiggers or red bugs. The mite also 

 fixes itself upon domestic animals, ])arti(nilarly in the Joints, around 

 tbe eye, and in the anus. Young ducks especially suffer from this para- 

 site and are even killed by its attacks. As a remedial measure it was 

 proposed to plow \\\) the sod of the garden several times during the 

 summer, and sprinkle the soil heavily with manure water and lime- 

 water, uprooting at the same time all shrubs and plants with hairy 

 leaves. The author did not learn whether this treatment produced 

 satisfactory results or not. — L. o. howakd. 



Occurrence of Distoma -westernianni in the United States, 

 H. B. Ward {Ck'utbl. Bald, und Far., 15 [1894), pp. 302-3(14; Vet. 

 Mag., 1894). — Distoma irestcnnaniii is a fluke found in man (China and 

 Japan), cats, dogs, and tigers. Ward has recently found it in a cat 

 in Ann Arbor, ^Michigan. The specific diagnosis, geograi)hical dis- 

 tribution, synonymy, and full bibliography of this fluke is given by 

 Stiles.' — c. w. STILES.
