Worma]s, or Warbles), reside in tumours beneath the skin of the animal attacked, for ex- ample the ox bot-fly; Cervical, when the grubs burrow into the maxillary and frontal si- nuses, through the nostrils, as is the case with the sheep breeze-fly ; or gastric, when the grubs, called in this case bots, are introduced into the stomach, like those of the horse gad-fly. We gather from various sources that the horse, sheep, ox, ass, reindeer, rhinoceros, stag, antelope, camel, hare, rabbit, rat and mouse are subject to the attacks of these in- sects, and it is mentioned as a singular anomaly that some of the genera which contain the largest species among them, inhabit the smallest animals. These insects whose habits are so formidable, and whose economy is so extraordinary, have the appearance of large hairy flies, the hairs being often coloured in transverse bands. Having thus learned something of the general history of the breeze-flies, let us now take them in order and more minutely examine the three several species we have alluded to. 1.—The Horse Breeze-Fly {(Estrus [gasterophUus] equi, Fab). Fi- 25. Male. joly thus dcscribcs this fly. The head is large and obtuse, the face light yellow with whitish silky fur, the eyes blackish, theanten- na3 ferruginous, the thorax grey, and the abdomen of a reddish yel- low, with black spots. The wings are whitish, not diaphanous, with a golden tint, and divided by a winding band of blackish colour ; the feet are palish yellow. The body of the female, fig. 26, is long, tap- ering and sharp pointed, while that of the male is round and obtuse. No quadruped is more infested by the breeze or bot-fly than the horse. During the months of July and August when horses are gene- rally turned out to grass, the (Estrus frequents the pastures for the purpose of laying its eggs.
