DIPTERA. 



Mr. 8. S. Rathvon has reared C. buccata 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. 116.) Other species live in the Opossum and 

 different species of field-mice. Cuterebm liorripilum Clark is 

 found throughout the United States, and C.cuniculi 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 r tit<ictjne,of Cayenne 

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

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

 homiuis," or originally attacks the monkey, 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 

 l><''hido, or Muche. The D. noxiaUs Goudot? 

 (Fig. 327) Ver inoyocml, 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 those 

 of the preceding genus. 



Dr. Leidy states in the Proceedings of the 

 Philadelphia Academy (1859), that several 

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

 tained by Dr. J. L. Lcconte 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." " Dr. Leconte informs us that his com- 

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

 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 Ivrefft a species of Batraclwmyia is parasitic 

 upon four species of Australian frogs. The larvae 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
