plumose scarcely more than half way to tip; four rows of 

 black cilia behind eyes ; a few bristle-like hairs on transverse 

 impression : anterior spiracular hairs light colored at tips only : 

 anterior face of posterior femur with three rows of bristles ; 

 anterior ventral row of bristles of middle femur complete: 

 second abdominal segment with two or three pairs of lateral 

 marginal bristles (one pair in savoryi) : fifth ventral plate very 

 similar but more brownish, the opening is much narrower and 

 scarcely, if at all, enlarged proximally, the pad-like structures 

 are blackish and smaller, and the " brushes " are smaller : for- 

 ceps are uniformly dark colored, prongs bent at right angles 

 to base, in profile more slender, tips more strongly bent for- 

 ward, minute spines as seen in profile near tips only. 



Holotype (male) ; collection of author. 



Described from five male specimens. 



Range. — British Columbia, Savory Island, July 3, 4, 5, 1918. 

 Collector, R. S. Sherman. 



The holotype was taken on Savory Island on July 5, 1919. 



The above described species are much more closely related 

 -than it has been possible to indicate in the drawings of the gen- 

 ital apparatus. The subdivisions of the penes are seen to be re- 

 markably alike if one has an opportunity to examine the actual 

 specimens. Both species are close to Sarcophaga magna Aldrich. 



Sarcophaga wrangeliensis n, sp. 



Male. — Four rows of black cilia behind eyes ; upper f rentals 

 as long or longer than lower f rontals : hairs at fold of calpyters 

 slightly darkened; posterior face of hind femur with ventral 

 row of long slender, almost hair-like bristles; posterior tibia 

 bearded ; middle femur without " comb " ; anterior acrostichals 

 absent ; three pairs posterior dorsocentrals, sometimes a fourth 

 very weak pair behind the first : abdominal nota with hairy ves- 

 titure beneath; fourth ventral plate with short, decumbent 

 bristles on posterior central portion; second segment with or 

 without two marginals, when present may be stout or slender : 

 second genital segment dull orange, shining. 



Length. — 9-10 mm. 



Head. — Viewed from front parafrontals and gense slightly 

 brassy. Breadth of front at narrowest part about one-third 

 eye width; cheek height about one-third that of eye. Front 

 prominent ; frontal vitta at its narrowest part about twice 

 width of either parafrontal. Third antennal segment scarcely
