INSCCUTOR INSCITI^ MENSTRUUS 27 



emasculator" was so labeled under a misapprehension, as proved 

 by its entire disagreement with the description. It is simply a 

 specimen that had been wrongly so determined by Fitch, after 

 describing his species. It is fasciata Swenk. C. fontinella Aus- 

 ten (nee Clark), 1895, Ann. Mag. N. H., ser. 6, Vols. XV, 

 XVI, is also this species. The location of Fitch's holotype of 

 emasculator is unknown. It was probably sent to some corres- 

 pondent. Little importance was attached to type specimens in 

 this country in Fitch's day. 



Bogeria fontinella Clk. — There are three specimens of this 

 species in the collection, from South Carolina, Florida, and 

 Mississippi. It is a larger species than either of the two pre- 

 ceding and decidedly broader, rather closely approaching buc- 

 cata in both form and size and like it evidently confined to rab- 

 bits. It may be at once distinguished from the squirrel flies by 

 the pronounced gray pruinosity of the mesoscutum. At first 

 sight, it appears identical with buccata, though slightly under- 

 sized, but is at once known by its densely poUinose anal seg- 

 ment. 



Bogeria grisea Coq. — This is a small northwestern form inter- 

 mediate between emasculator and fasciata. 

 Bogeria scudderi, new species. 



Length of body, 16 to 20 mm. ; of wing, 14 to 16 mm. ; width 

 of thorax, 7 to 8 mm. Three males as follows, all reared from

 collected by Mr. N. P. Scudder; Round Mountain, Texas, fly

 from leg of host; Beltsville, Maryland, larva collected by Mr. 

 E. B. Marshall, November 24, 1911. (All det. Coqt. as buccata 

 Fab.) 



Differs from buccata F. as follows : Narrower in form. Male 

 front very narrow. Mesoscutum and scutellum chocolate color, 

 clothed with short blackish pile, interspersed with a few grayish 

 hairs along transverse suture. Abdomen chestnut-brown, the
