SARCOPHAGA AND ALLIES 29 



blunt tips ordinarily lying between the arms of the 

 penis like a part of that organ; the elaspers and penis 

 seem to coalesee at base, and all lie deep in the groove 

 of the under side of the hypopygium. Penis with but 

 one segment, yellow, simple, much like that of Sar- 

 cophaga coinmunis; it has a pair of conspicuous 

 straight black anterior plates. 



Legs black, middle femur with comb; middle 

 tibia with two bristles on the outer front side, and 

 with long villosity in the inner, which is strikingly long 

 at the Axry tip; hind tibia also with villosity, but not 

 so long at the tip ; both of these tibias are curved, and 

 the hind femur is thickened and curved. 



Female. Front .413 of head (average of three, 

 ■ — ^.405, .412, .421) ; Genital segment brown and shin 

 ing above, the orifice transverse. Femora and tibiae 

 simple, but the hind femora are a little curved. 



Length IY2 to 14 mm. 



Five males and three females: four males and 

 three females were taken at Moscow, Idaho, by the 

 writer, some on flowers of goldenrod and parsnips, at 

 dates from June 24 to Sept. 4. The other male is 

 from Koehler, New Mexico (W. R. Walton).

 ^ly attention was called to Walker's Sarcophaga 

 vigil by C. W. Johnson, who had identified it; as I 

 had just been studying the type of Paraph yio chit- 

 tendeni, it was easy to detect the synonymy. Walker's 

 description applies ^ery well, and tlie species is so 

 unique in coloration as to leave little doubt of its cor- 

 rect identification.
