the tip of the median lobe of the male genitalia is not wider than the tip of 

 the lateral lobe, and the median carina on the eighth abdominal tergite of 

 the female extends beyond the apical notch, whereas in femorata the antenna 

 is gradually narrowed to the apex, and the last segment is narrower than the 

 tenth, the tip of the median lobe of the male genitalia is wider than the tip of 

 the lateral lobe, and the median carina on the eighth abdominal tergite of the 

 female does not extend beyond the apical notch. In a large series of reared 

 specimens of these species the above characters are constant, with very little 

 variation, but in collected specimens intermediate forms will be found. 

 Length 9-16 mm., width 3.75-7 mm. 



Type locality. — Pennsylvania (probably York County). 



Distribution. — Specimens have been examined from Manitoba, 

 Canada, and the District of Columbia, and from various localities in 

 the following States: Arkansas, Connecticut, Florida, Illinois, Indi- 

 ana, Iowa, Kansas, Louisiana, Maryland, Massachusetts, Michigan, 

 Minnesota, Missouri, New Hampshire, New Jersey, New York, North 

 Carolina, Oklahoma, Pennsylvania, Tennessee, Texas, Virginia, and 

 West Virginia, 



Hosts. — Adults have been examined that were reared from chestnut 

 (Castanea dentata (Marshall) Borkhausen), white oak (Quercus 

 alba Linnaeus), and bur oak {Quercus macrocarpa Michaux). 



Melsheimer had both sexes when he described the species, and a 

 female examined in the LeConte collection labeled "rugosiceps" 

 may be one of the types. About the same variation in this species is 

 found as that given for femorata.

This species so closely resembles femorata that it seems necessary 

 merely to give the differences. 



Male. — Differing from the male of femorata in having the under side of the 

 body and legs more greenish, the antennal segments distinctly pale yellow 

 toward outer margins, the eighth abdominal tergite slightly, broadly emarginate 

 at apex, and the sides of the genitalia broadly rounded and not constricted 

 near apex. 



Female. — Differing from the female of femorata in not having the eighth 

 abdominal tergite deeply depressed on each side of the median carina. 



Length 8-13 mm., width 3-5.5 mm. 



Type locality. — Pennsylvania (probably York County). 



Redescribed from a male in the United States National Museum 

 from Philadelphia, Pa., which has been compared with a male in 

 the Melsheimer collection labeled "viridiceps M. Pa. Ziegler." If 

 this is not the type, it is a specimen compared by Ziegler with the 



Distribution. — Specimens have been examined from the District of 

 Columbia and various localities in the following States : Georgia, Illi- 

 nois, Iowa, Maryland, Massachusetts, Michigan, Minnesota, Mis- 

 souri, Nebraska, New Jersey, New York, Pennsylvania, Rhode Island, 

 Texas, Virginia, and West Virginia.
