406 DIPTERA. 



Mr. S. S. Ratbvon has reared C. buccata Fabr. (Fig. 32G, and 

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

 emerged from the region of the kidne3-s." (American Ento- 

 mologist, p. IIG.) Other species live in the Opqssum and 

 different species of field-mice. Cuterebra 1iorri2^Uum Clark is 

 found throughout the United States, and C c^tniculi 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 tnacaque^ of Cayenne 

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

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

 hominis," or originally attacks the monkey, dog, or other mam- 

 mal. In Ca3'enne the species attacking man is called the Ver 

 l^T) Macaque ; in Brazil (Para) Ura ; in Costa 

 Rica, Torcel ; in New Grenada, Gnsano 

 j^eludo, or Muche. The D. noxiaUs 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 greatl}' 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 

 ^'^4' Xj Philadelphia Academy (1859), that several 

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

 tained b}' Dr. J. L. Leconte in Honduras, 

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

 panions Avero not aware of the time when the eggs of the larva>, 

 obtained b}' 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 Batracliomyia is parasitic 

 upon four species of Australian frogs. The larvai 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
