hofera or a new genus. It is evidently a subcutaneous bot, and not 

 a head or throat bot. 



The larvae recorded in Insect Life, II, p. Ii6, from nasal passages 

 of man in California are third-stage screw-worms, Cochliomyia 

 macellaria Fab. I have examined the material, which is now in the 

 U. S. National Museum. 



The larvae from the throat of hogs near Parkersburg, West Vir- 

 ginia, recorded in Insect Life, III, pp. 161-162, are not Cepheneniyia, 

 nor are they any other known oestrid genus, nor yet screw-worms, 

 Sarcophagids, nor Muscids (Calliphorids). The material, now in 

 the National Museum, consists of a single immature third-stage larva 

 of decided oestrid aspect, with double mouth-hooks and elaborately 

 sinuous anal stigmatic slits. 



It is evident from the foregoing that our knowledge of Cephe- 

 neniyia in America is extremely defective. The flies themselves are 

 seldom met with and usually difficult to capture. The male flies 

 especially frequent mountain tops and collectors who visit such places 

 would confer a great favor by capturing them. While they fly with 

 extreme swiftness, they are at times found resting in sunny places. 

 The female flies are less often found on mountain tops but frequent 

 the haunts of the host. It appears that the only practicable way of 

 securing them in the open is to shoot them with .22 caliber cartridges 

 loaded with dust shot or fine sand. No American female flies are 

 yet known in collections. 



Occasionally other ruminant hosts than Cervidcc may be attacked 

 by the flies of this genus. I have recently secured authentic informa- 

 tion of bots in the heads of the pronghorn antelope, Antilocapra 

 amcricana Ord, which is of extreme interest in this connection. Mr. 

 Otto Schoenberg, superintendent of the Cedro Ranger Station, Man- 

 zano National Forest Reserve, who spent twelve years with the 

 Apaches in Arizona, tells me positively that he has taken large bots 

 from the nasal cavities of the antelope in central Arizona years ago. 

 This is the first record of the kind known to me, and I consider the 

 authority unquestionable. 



The greatest service can be rendered by persons who have oppor- 

 tunity to examine fresh game heads in whatever locality. The best 

 chance of finding mature larvae, from which the fly can be reared, 

 appears to be in winter or early spring. Mature bots from the heads
