schaeffer: donaciini of the new world. 89 
Michigan: Lake Superior (Leconte). 
Colorado: Alamosa (Leconte coll.). 
As already pointed out in Journ. N. Y. Ent. Soc, vol. XXVII, p. 309, 
this is not a variety of proxtma or cincticornis but is distinct from both. 
The head is relatively smaller and more distinctly prolonged behind the 
eyes, which latter are smaller and less prominent. The prothorax is 
less transverse and in form more nearly as in rugosa, the last dorsal 
segment of the female is different, the intercoxal process of mesosternum 
narrower and the teeth of the posterior femora of the males are nearer 
together. It is more closely related to the European versicolor ea and 
allies than to any of the American species. 
DoNACiA HiRTicOLLis Kirby. 
Moderately elongate, somewhat robust and feebly depressed; color 
of upper surface metallic blue, green or purple, laterally and the pro- 
thoracic impressions more or less distinctly cupreous or golden-green, 
occasionally elytra flavous; antennae black; legs metallic green. 
Head moderately constricted behind the eyes, which are rather large 
and prominent; median line deeply impressed; posterior tubercles feeble 
or absent; surface densely and finely punctate, antennae moderately 
long, not reaching the middle of elytra; second and third joints small, 
together as long or slightly longer than the first joint. 
Prothorax as wide at apex as long; anterior angles more or less 
distinct, occasionally oblique; posterior angles feebly prominent; lateral 
tubercle distinct; sides below latter more or less distinctly arcuate; 
surface uneven, densely punctate and pubescent with short grayish- 
white hairs; median line and anterior transverse impression more or 
less distinct. 
Elytra truncate or emarginate at apex; ante-median and post- 
median impressions distinct or absent; strial punctures moderate, 
gradually smaller towards apex; the fine, narrow sutural bead absent; 
surface sculpture variable from smooth and shining to more or less 
distinctly rugose and less shining. 
Body below densely and finely punctate and densely pubescent with 
short, grayish-white hairs; intercoxal process of mesosternum rather 
narrow, less than half the width of the cavities; posterior femora rather 
feebly clavate, extending to the apex of the fourth ventral segment or 
slightly shorter, armed below with a small tooth, which is often absent in 
the female. Length: 6-9 mm. 
Male: Last dorsal segment truncate at apex, last ventral segment 
truncate and more or less distinctly depressed at middle of apex.
