DoNACiA DisTiNCTA Lecontc. 
Moderately elongate, depressed; color including legs and antennae 
aeneous, cupreous or rarely bright metallic green. 
Head relatively deeply constricted behind the eyes, which are 
prominent and moderately large ; median impressed line deep ; posterior 
tubercles generally distinct; surface densely punctate with moderate 
punctures; antennae extending to about the middle of elytra or slightly 
beyond, second and third joints small, the latter slightly longer than 
second, occasionally nearly as long as the fourth joint. 
Prothorax about as wide as long or slightly wider; sides rather 
feebly converging towards base; anterior angles distinct, sometimes 
prominent and more or less projecting laterally; posterior angles more 
or less prominent; lateral tubercles moderately distinct; median im- 
pressed line distinct; surface sculpture variable from sparsely and some- 
what finely punctate with finely impressed transverse or oblique lines 
between the punctures to rather coarsely and densely punctate, laterally 
strigate-rugose. 
Elytra depressed; apices truncate, outer angle broadly rounded; 
ante-median impressions generally very distinct; post-median im- 
pressions less deep and more or less distinctly continued to nearly to 
apex; laterally there is also frequently a shallow, elongate impression; 
surface without coarse transverse rugae but intervals finely transversely 
strigate-rugose from base to apex, dense, but scarcely finer at apex and 
sides than in basal half; serial punctures moderate, finer towards apex. 
Body below closely punctate with small punctures; pubescence 
white, rather short and not dense; pubescent space near anterior coxae 
small; intercoxal process of mesosternum slightly narrower than half 
of the width of the cavities; posterior femora reaching to the apex of 
the third ventral segment, armed below in both sexes with a moderate 
tooth. Length: 7-9 mm. 
Male and female differ very little except that the females, as usual, 
are stouter, have shorter antennae and the last ventral is not truncate 
and impressed at middle but rounded at apex. The last dorsal segment 
of both sexes is emarginate at middle of apex.
