Mr. S. S. Ratbvon has reared C bnccata Fabr. (Fig. 32G, antl 

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

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

 mologist, p. 11 G.) Other species live in the Opossum and 

 different species of field-mice. Cuterebra horripilum Clark is 

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

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

 according to Coquerel, in the bots of horses. 



The genus Dermatohia includes the Ver macaque, of Caj'enne 

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

 and it is disputed whether it be a true indigenous "CEstrus 

 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) Ura ; in Costa 

 Rica, Torcel ; in New Grenada, Gusano 

 X)eludo, or Muche. The D. noxialis Goudot? 

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

 and is found in Mexico and New Grenada. 

 The larvse are long, C3dindrical, S-shapcd, 

 difffering greatly in form from others of this 

 family. The flies are closely allied to those 

 of the preceding genus. 



Dr. Leidy states in the Proceedings of the 

 Philadelphia Academj^ (1859), that several 

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

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

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

 thighs, and were suspected to have been introduced when the 

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

 panions were not aware of the time when the eggs of the larvas, 

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

 that the presence of the larva gave rise to comparativel}- little 

 uneasiness." 



According to Krefft a species of Batrachomyia is parasitic 

 upon four species of Australian frogs. The larvse are found 

 between the skin and the flesh behind the tj-mpanum ; the}- 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
