schaeffer: donaciini of the new world. 77 
New Jersey : Centerton, May (Liebeck) ; Malaga, May (Shoemaker) ; 
Burlington Co. (Castle) ; Clayton, June (Wenzel) ; Newfield, May 
(Wenzel). 
Taken on the flowers and leaves of the white water lily, Castalia 
odorata, but Mr. Wenzel took a single specimen at Newfield, N. J., on 
the leaves of Nymphaea advena. 
The range of this species is very limited at present but very likely 
will be found further south and probably north also if properly looked for. 
This species is readily identified by its rather narrow, feebly clavate, 
unarmed posterior femora and rather dull, alutaceous and finely punctate 
prothorax. It looks somewhat like parvidens but in this species the 
prothorax is generally more or less shining in both sexes, the antennal 
joints are shorter and stouter and the hind femora shorter and in both 
sexes armed below with a distinct, small tooth. 
DoNACiA PARVIDENS Schaeffer, 
Moderately elongate, shining, pale or dark castaneous with or without 
metallic tint or more or less greenish-blue; head and prothorax cupreous, 
antennae black, joints more or less distinctly reddish at base; underside 
castaneous, sides often darker; legs castaneous, upper edge of femora and 
apex of tibiae in the darker specimens more or less black. 
Head feebly constricted behind the eyes which are large and promi- 
nent; median line deeply impressed; surface densely and rather finely 
punctate; antennae extending to about the middle of elytra, third joint 
one third or one fourth longer than second. 
Prothorax slightly wider at apex than long; sides sub-parallel and 
more or less distinctly sinuate; lateral tubercle feeble, apical angle 
distinct; basal angle moderately prominent; surface shining, scarcely 
alutaceous in the male, less shining and frequently dull and alutaceous 
in the female, rather sparsely punctate but often densely punctate along 
the deeply impressed and nearly entire median line and broad sub-basal 
impression ; laterally, including the feeble tubercle, rather coarsely rugose. 
Elytra shining; apices truncate, outer angle feebly distinct and 
more or less rounded; ante-median impression on each side of suture 
generally distinct; post-median impression mostly absent; intervals 
smooth with scarcely visible, minute punctures, more or less convex, 
especially towards apex; strial punctures moderately large, slightly 
smaller towards apex. 
Body below densely clothed with short, white pubescence ; pubescent 
space near anterior coxae large ; mesosternal process between the middle
