schaeffer: donaciini of the new world. 147 
Since then I have seen more material of this species and among them 
were specimens with distinct median line of the prothorax which in some 
specimens answers Lacordaire's description. 
In the majority of the forty odd specimens seen some of the outer 
joints of the antennae are entirely reddish, the inner ones metallic and 
not or feebly reddish at base, a few have the antennae and legs entirely 
reddish but in none of the specimens are all the antennal joints distinctly 
annulate, that is, bright red at base and black or metallic at apex. 
D. fulvipes Lac. might be confused with pusilla but it is a little 
stouter insect with the outer antennal joints narrow and elongate and 
not distinctly stouter than the inner ones, the lateral margin of elytra 
is never evenly acute in its entire length, the posterior femora are more 
distinctly clavate and have below in both sexes a longer, acute tooth and 
the last dorsal segment of the female is distinctly incised at middle of 
apex — entire in females of pusilla. The following species, D. wallisi, 
is also very similar to fulvipes and remarks on the differences between 
the two will be found under the former. 
The Siberian annularis Reit. is very close to fulvipes, the females, 
however, more than the males. The Siberian species is more elongate, 
the antennal joints two to eleven usually distinctly annulate, though one 
female has the first five joints metallic without red at base, the outer 
joints red and obscurely darker at apex; the prothorax in the males is 
apparently slightly longer and more distinctly converging behind the 
lateral tubercle, the females have the prothorax more like fulvipes and 
have also the peculiar incisure at middle of apex of the last dorsal segment. 
The head, sculpture of prothorax and elytra, form of antennae and 
legs are as in fulvipes. 
DoNACiA wAivUSi new species. 
Rather narrow and elongate ; color of upper surface bronze, cupreous, 
obscurely metallic green or blue, rarely golden ; antennae and legs usually 
entirely flavous, very rarely antennae almost entirely black; below 
metallic, last ventral segment at apex more or less pale. 
Head slightly prolonged, truncate and distinctly constricted behind; 
eyes prominent; median line fine and deeply impressed; surface densely 
punctate; antennae extending nearly to or slightly beyond the middle 
of elytra, third joint slightly longer than second and about as long, or 
nearly so, as the first joint, outer joints rather narrow and elongate. 
Prothorax shining, about as wide at apex as long, occasionally very 
slightly longer than wide; anterior angles distinct, often rounded.
