PARASITES OF ANIMALS TRANSMISSIBLE TO MAN. 



Prof. A. Kailliet of Paris lias just sent us an interesting iiamphletof 

 some 50 pages devoted to a consideration of the parasites transmissible 

 from animals to man, wliicli is, for the most part, occupied with the 

 treatment of intestinal parasites, but which also takes up certain insects. 

 The latter comprise principally external parasites, and of these largely 

 those which are free or temporary. The species principally mentioned 

 under this category are the Stable Fly {Stomoxys calcitrans), the Afri- 

 can Tsetse Fly {Glossina morsitans), the commoji Horse ¥ly {Hippohosea 

 equina), and species of Simulium and Pulex. These are all of import- 

 ance on account of the fact that they may become transmitters of con- 

 tagious diseases. Among the Arachnida, he mentions the species of 

 Dermanyssus and Argas. Some attention is also paid to Ochromyia, 

 Sarcophaga, Hypoderma, andDermatobia, all of which occasionally in- 

 fest human beings, while the Ohigo of Tropical America {Sarcopsylla 

 penetrans), the Dog Tick (Ixodes ricinus), the larval Trombidium and 

 several species of the family Sarcoptidae are also treated briefly. 



FURTHER ILLUSTRATIONS OF THE ROSE SLUGS. 



It was our intention in the article in the September number of Insect 

 Life on Eose Saw-flies in the United States to have presented figures 

 of the commoner species Monostegia roswj which we had made some 

 years ago. These illustrations are given herewith. Fig. 35 represents
