Mr. S. S. Rathvon has reared C. biiccata Fabr. (Fig. 326, and 

 side view) from the body of a striped squirrel, the larvae having 

 emerged from the region of the kidneys." (American Ento- 

 mologist, p. IK!.) Other species live in the Opossum and 

 different species of field-mice. Cuterebra liorripilvm Clark is 

 found throughout the United States, and C. cwniculi Clark lives 

 in the hare and rabbit, in the Southern States, and is found, 

 according to Coquerel, in the bots of horses. 



The genus Dermatobia includes the Ver macaque^ of Cayenne 

 and Mexico, found beneath the skin of man in tropical America , 

 and it is disputed whether it be a true indigenous u CEstrns 

 hominis," or originally attacks the monke}-, dog, or other mam- 

 mal. In Cayenne the species attacking man is called the Ver 

 Macaque ; in Brazil (Para) lira ; in Costa 

 Rica, Torcd ; in New Grenada, Gustnm 

 peludo, or Muche. The I), iioxialis Goudot? 

 (Fig. 327) Ver moyocuil, lives on the dog, 

 and is found in Mexico and New Grenada. 

 The larva- are long, cylindrical, S-shaped, 

 differing greatly in form from others of this 

 family. The flies are closely allied to thoso 

 of the preceding genus. 



Dr. Leidy states in the Proceedings of the 

 Philadelphia Actulemy (1859), that several 

 specimens of the larva of a bot-fly were ob- 

 tained by Dr. J. L. Leconte in Honduras, 

 from his travelling companions. They were " usually found be- 

 neath the skin of the shoulders, breasts, arms, buttocks and 

 thighs, and were suspected to have been introduced when the 

 persons were bathing." lt Dr. Leconte informs us that his com- 

 panions were not aware of the time when the eggs of the larva-, 

 obtained by him, were deposited in their bodies. He also states 

 that the presence of the larva gave rise to comparatively little 

 uneasiness." 



According to Krefft a species of Bcitruchomyia is parasitic 

 upon four species of Australian frogs. The larva* are found 

 between the skin and the flesh behind the tympanum ; they are 

 of a yellow color and may be squeezed through a small open- 

 ing that exists over them. When they quit the frog the latter
