schaeffer: donaciini of the; new world. 129 
Nebraska: "Neb." (coll. Marshall). 
This species is taken by Messrs. Davis and Liebeck on Peltandra 
and on Pyrus arhutiJoUa by Dr. Britton. Prof. Blatchley finds it common 
on reeds, rushes and Peltandra. 
The following two varieties are recognized: 
var. SHOEMAKERi new variety. 
Similar to typical flavipes but smaller and narrower, antennal joints 
longer and generally bicolored, or entirely black, occasionally entirely 
red ; posterior femora usually bicolored, with the tooth sometimes rather 
short and blunt; specimens, however, occur with entirely reddish femora; 
the elytra, besides the more or less distinct larger transverse rugae, have 
the intervals, especially in the males, more or less distinctly rugulose. 
Length: 5.5-7.5 mm. 
New York: Bronx Park, June- (Davis) ; lona Island, May (Schott); 
Rockaway Beach, Long Island, June (Schott). 
New Jersey : Malaga, June (Shoemaker) ; Wenona, May (Wenzel) ; 
Centerton, June (Liebeck) ; Pt. Pleasant, July (Schott) ; Masonville, 
May (Wenzel). 
District of Columbia: Washington, October (Chapin, Barber and 
Notman, sifting) ; November (Hubbard and Schwarz) ; Eastern 
Branch, December (McAtee in old leaves). 
Virginia: Dyke, May (Johnson). 
Found sweeping various grasses and Sagittaria growing together by 
Mr. Wenzel. 
The type is a specimen from Malaga, N. J., collected by Mr. Shoe- 
maker from whom I received the first specimens of this form and which 
I named after him in recognition of the interest he had taken in Donacias 
during my investigations. Paratypes in the National Museum. The 
specimens from southern New Jersey, Washington and Virginia, especially 
the males, look quite distinct from the typically northern specimens, 
however, among the few females are one or two which are rather inter- 
mediate. 
var. LODINGI new variety. 
This form is more elongate than the var. shoemakeri, the elytra 
slightly more depressed and generally duller, caused by the denser sculp- 
ture of the intervals; the prothorax also is more densely rugose obscuring 
the distinctness of the lateral tubercles and sharpness of the median 
line and the antennal joints in the few specimens seen are either annulate 
or entirely black and the femora bicolored. Length: 7-8 mm.
