very jfine, narrow sutural bead of the elytra is absent in this species. In 
all other North American Donacias, with the exception of harrisi, it is 
present, though often partly obliterated in militaris. 
DoNACiA PUBESCENS Lcconte. 
Moderately elongate, slightly depressed; above and below with 
golden-yellow pubescence; color rufo-flavous, without or with a more 
or less distinct golden or metallic green tint; antennae entirely pale, 
partly black or entirely black; head, excepting the mouth parts, generally 
metallic green. 
Head rather feebly constricted behind the eyes, which are moder- 
ately large and moderately prominent; median line deep; surface 
sculpture obscured by the dense pubescence; antennae rather short, 
extending not quite to the middleof elytra, third joint longer than second 
and as long or slightly shorter than the first joint. 
Prothorax about one half wider at apex than long; sides gradually 
converging towards base; anterior angles distinct but not prominent; 
basal angles not prominent; median line fine, generally obscured by the 
dense pubescence; lateral tubercles more or less distinct; surface densely 
pubescent obscuring the punctuation. 
Elytra closely pubescent; ante-median impressions generally dis- 
tinct, post-median faint or absent; apices more or less distinctly rounded; 
strial punctures moderate; lateral marginal ridge, which is usually 
distinct and separating the epipleurae, absent in this species. 
Body below finely and densely punctate; pubescence moderately 
dense; intercoxal process of mesosternum rather narrow. Length: 
6-7 mm. 
Male: First ventral segment moderately deeply excavate at middle; 
last ventral segment at apex feebly depressed at middle; posterior 
femora feebly clavate, armed below with two small teeth; last dorsal 
segment broadly rounded at apex. 
Female: First ventral segment feebly depressed at middle; last 
ventral segment rounded at apex; posterior femora with one very small 
tooth below, which is occasionally absent; last dorsal segment sub- 
triangular, rounded at apex.
