(EstrusomsLinn., the Sheep Bot-fly, is of a Fi&- :!-;- dirty ash color, with a fuscous ashen, banded, and obscurelyspotted thorax. The abdomen is marbled with yellowish andwhite flecks, and is hairy at the end. The larva lives, duringApril, May and June, in the frontal sinus of the sheep, and alsoin the nasal cavity, whence it falls to the ground. It changesto a pupa in twenty-four hours, and the fly appears during the;summer. Cuterebra, lias the third joint of the antennae oval orelliptical and the bristle is dorsal and feathered ; the speciesare short, very plump and hairy flies, with a proboscis elbowedat the base, and with a metallic shining rounded larvae live in subcutaneous bots beneath the skin of vari-ous animals. One species (the C. emasculator of Fitch) livesin the scrotum of the squirrel, which it is known to DIPTEKA. Mr. S. S. Rathvon has reared C. biiccata Fabr. (Fig. 326, andside view) from the body of a striped squirrel, the larvae havingemerged from the region of the kidneys. (American Ento-mologist, p. IK!.) Other species live in the Opossum anddifferent species of field-mice. Cuterebra liorripilvm Clark isfound throughout the United States, and C. cwniculi Clark livesin 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 Cayenneand Mexico, found beneath the skin of man in tropical America,and it is disputed whether it be a true indigenous uCEstrnshominis, or originally attacks the monke}-, dog, or other mam-mal. In Cayenne the species attacking man is called the VerMacaque ; in Brazil (Para) lira; in CostaRica, Torcd ; in New Grenada, Gustn
