broad transverse band on each gastric segment are light or darli brown. Some 

 specimens have the thorax and gaster piceous, with the thoracic dorsum and 

 gastric bands blacli ; or more rarely the body may be black, with the pronotum, 

 legs and petiole dark red or brown. In the female, the thorax is nearly always 

 black above, the gaster dark brown or with yellow base and pale borders to 

 the segments. The male usually has the thorax, gaster, petiole, legs, antennse 

 and anterior portions of the head brown or piceous, but specimens are occa- 

 :sionally found with the thorax and gaster black. The wings of the female and 

 male are, as a rule, less suffused with yellow than in the typical castaneus. 



C. americanus occurs over much the same territory as castaneus, but it 

 ranges further north and is much more common. I have seen specimens 

 from the following localities : 



New Hampshire: Pelham (Bridwell). 



Massachusetts: Weston, Newton and Middlesex Fells, Boston (A. P. 

 Morse) ; Essex County and Mt. Tom (G. B. King) ; Sutton (Bost. Soc. 

 Nat. Hist.) ; Andover (Morse and King) ; Medford (Dall) ; Blue Hills, 

 Arnold Arboretum, Boston and Ellisville (Wheeler). 



New York: Montgomery; Staten Island (W. T. Davis). 



Pennsylvania: Eockville (H. Viereck) ; Edge Hill (Greene). 



New Jersey: Manumuskin, lona and Da Costa (C. Daecke) ; JameS' 

 burg and Patterson (W. T. Davis) ; Halifax, Newfoundland and Lake- 

 hurst (Wheeler) ; Lacy; Fort Lee (W. Beutenmueller). 



North Carolina: Black Mts. (W. Beutenmueller); Lake Toxaway 

 (Mrs. A. T. Slosson). 



Georgia: Clayton, 2000-3000 ft. (W. T. Davis) ; Chickamauga. 



Florida: Quincy (W. A. Hooker). 



Indiana: Wyandotte and Mitchell (W. S. Blatchley).. 



Illinois: Eockford (Wheeler). 



Missouri: (Forel). 



Indian Territory: Ardmore (C. E. Jones). 



Oklahoma: Ponca City (A. C. Burrill). 



Texas: College Station (F. C. Pratt); Palestine (F. C. Bishopp) ; 

 Calvert (C. E. Jones). 



C. americanus is as variable in color as the typical castaneus is con- 

 stant. As these forms are distinguished merely by the coloring of the 

 head and the foveolation of the cheeks, americanus would properly be 

 merely a variety, but I have followed Emery in regarding it as a sub- 

 species, for the reason that I have been quite as unsuccessful as he has 

 been in finding transitions between the two forms.
