DIPTERA. 



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

 side view) from the bod}- of a striped squirrel, the hirvse having 

 emerged from tlie legion of the kidneys." (American P^nto- 

 mologist, p. IIG.) Other species live in tlie Opossum and 

 different species of field-mice. Cuterehra liorripilum Clark is 

 found throughout the United States, and C. cunicxdi 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 l)eneath the skin of man in tropical America, 

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

 hominis," 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 

 j)ehido, or Muche. The D. noxiaUs Goudot? 

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

 and is found in Mexico and New Grenada. 

 The larvte are long, cylindrical, S-shaped, 

 differing greatly in form from others of this 

 famil}'. 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-fl}' were ob- 

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

 from his travelling companions. They were " usual!}' 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 were not awai'e of the time when tlie 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 Krefft a species of Batrachomyia is parasitic 

 upon four species of Australian frogs. The larvae are found 

 between the skin and tlie 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
