WHEELER, NORTH AMERICAN ANTS 339 



Worker major and minor. 



Closely resembling the typical pennsylv aniens in sculpture and in the length 

 and abundance of the hairs and pubescence, but differing in color. The hairs 

 and pubescence are bright golden yellow instead of pale yellow or white. 

 Thorax, petiole, coxse, femora and base of first gastric segment yellowish fer- 

 ruginous ; pronotum and often also the mesonotum black. Antennal scapes 

 black, with yellow tips and insertions ; funiculi, mandibles, anterior border of 

 head, tibite and tarsi deep red ; posterior margins of gastric segments yellow. 



Female. 



Resembling the worker. Pronotum, mesonotum, except its anterior portion, 

 scutellum and metanotum black. Remainder of thorax, base and sometimes 

 the whole of the first and the base of the second segment yellowish red. Wings 

 rich yellowish brown with resin-yellow veins and stigma. Hairs and pubes- 

 cence golden yellow, shorter than in the worker, especially on the gaster. 



Male. 



Differing from the male of pennsylvanicus in having the whole of the 

 antenufe and legs, and sometimes also the metasterna, coxse and ventral por- 

 tion of the petiole, red or brown. Edges of gastric segments dull yellow. The 

 whole body is densely and coarsely shagreened and the gaster is somewhat 

 more opaque than in pennsylvanicus. 



Described from numerous specimens taken in the following localities : 



Massachusetts: Sherborn (A. P. Morse); Medford (Mus. Comp. 

 Zool.) ; Boston (Wheeler). 



Connecticut: New Haven (Moore and Viereck) ; Orange and New 

 Canaan (W. E. Britton). 



New York: West Farms (J. Angus); Mosholn and Bronxville 

 (Wheeler) ; Forest Park (G. v. Krockow) ; Staten Island (W. T. Davis). 



New Jersey: Delair (C. Daecke) ; Camden and Boonton (H.Yiereck) ; 

 Westville (Phila. Acad. Sci.) ; Fort Lee and Great Notch (Wheeler); 

 Ocean Count3^ 



Maryland: Pomona (H. Viereck). 



Pennsylvania : Lawndale. 



Indiana: Mitchell (W. S. Blatchley). 



Illinois : Rockford (Wheeler) ; Mossville (F. Blake) ; Urbana (Pricer). 



This variety has a much more limited range than pennsylvanicus, since 

 it does not extend as far south or north, and seems to be confined to 

 rather low, warm woodlands. It varies so little that it might be regarded 

 as a subspecies. I have been unable to find any specimens that would 

 represent transitions between ferruqineus and any of the other forms of 

 herculeanus. In certain respects it resembles the Japanese subspecies 

 ohscuripes Mayr, but this form has much darker legs and in sculpture 

 and pilosity is much like ligniperda.
