median marginal bristles; fourth with a marginal row of about 14 

 bristles ; fifth sternite divided, rather brownish, and with long black 

 hair along the inner edges. 



Hypopygium black; first segment distinctly poUinose, and with 

 scattered black hair; second segment black, rather shining; forceps 

 black, slightly curved anteriorly and with a distinct tooth at about 

 the middle of the blunt tip ; accessory plate somewhat reddish, quite 

 long and pointing anteriorly; posterior clasper black, short, curved 

 slightly anteriorly and with a blunt tip ; anterior clasper long, black, 

 curved strongly forward; penis with the first segment semitrans- 

 parent whit^e, short, slightly curved anteriorly and covered with very 

 minute short v%'hite spines; second segment mostly black, its tip 

 sharply pointed anteriorly and terminating in a sharp point, a 

 small tube projecting downward, anteriorly with a pair of small 

 black hooklike plates. 



Wing hyaline; costal spine absent; third costal section as long as 

 fifth; first vein bare; third vein with a few scattered setulae. 



Legs black; middle femur with comb; middle tibia with two an- 

 terior dorsal bristles; hind tibia with long scattered hairs. 



Type locality. — Miami County, Ohio. 



Type and ^«mfy/^e.— U.S.N.M. no. 51687. 



Remarhs. — Described from the holotype male collected on June 14, 

 1928, and one paratype male collected in Lucas County, Ohio, June 

 19, 1928, by David G. Hall. 



This species differs mainly from its closest relative, Sarcophaga 

 morosa Aldrich, in the shape of the accessory plate, which in S. 

 morosa is triangular, the angles approximately equal. In S. paulina 

 the anterior angle is distinctly larger than the opposite angle, causing 

 the free angle to point anteriorly, not directly downward as in 

 S. 7norosa.

 facials silvery pollinose, the latter with the usual minute bristles be- 

 low near eye ; frontal bristles about 12 in number, the rows diverging 

 below to about the middle of the second antennal segment; orbital 

 bristles absent; outer vertical bristles absent; antenna black, second
