of the deer family. Ccphcnomyia rufibarbis Mg. (name changed to 

 anriharhis Mg. in the Palaarctic Catalogue on account of " page 

 priority") is found in the stag; idrichii Br., in the elk; trompc L., 

 in the reindeer; and stirmdator Clark in the roe (the Pal. Cat. also 

 mentions Cervtis pygargus). They are at times found in large 

 numbers in the host; Brauer (p. 192) states that stags and roes dying 

 in spring are often so badly infected that the hots must be a principal 

 cause of their death. 



From Patagonia Guerin described Ccphcnomyia graiidis (Iconog. 

 regne anim., 547, 1843 or earlier) from an adult, nothing being re- 

 ported about its life history. 



The preceding data include all the described species, outside North 

 America, as far as the literature is known to the writer. 



In North America only one doubtful adult has been mentioned 

 up to the present, the one which was described from Georgia as 

 CEstrus phobifer by Clark, Essay on Bots, 69, 191 5. The description 

 of this species was much too general and too brief to indicate the 

 generic relations; Brauer, however, happened to get hold of an old 

 portfolio of Meigen's drawings just as his Monograph was nearly 

 printed, among which was a drawing labeled GLstrtis phobifer. In 

 the belief that Meigen had actually seen and drawn Clark's specimen, 

 Brauer reproduces this sketch (pi. v, f. 11). with notes on page 291. 

 The venation indicates a Ccphcnomyia, but the rest of the sketch 

 hardly shows any characters. The century which has passed has 

 brought no further light on the matter, and we can only refer the 

 species to Ccphcnomyia with an interrogation mark as heretofore. 

 In any case, it is not the same as the species herein described. 



There are however several references to larvae from North Amer- 

 ica in literature. On page 202 of his Monograph, Brauer mentions 

 larvse of Ccphcnomyia ulrichii Br. from throat of an elk in North 

 America, sent him by Osten Sacken; as no North American adults 

 are known, there must be considerable doubt of the specific identity 

 of the species. 



On page 211, Brauer describes two larv?e sent him from North 

 America by Osten Sacken, taken from Ccri'us macrotis Say in the 

 northwestern part of the United States (in copying the reference in 

 my catalogue, I inadvertently introduced the word by before Say) : 

 in the index this species is called Ccph. macrotis, but no specific
