schaeffer: donaciini of the; new world. 87 
Body below very finely and densely punctate and very densely 
pubescent with very short, fine, white hairs, the pubescence hiding the 
surface color and sculpture; pubescent space near anterior coxae wide; 
posterior femora moderately incrassate in more than apical half; inter- 
coxal process of mesosternum as wide as the coxal cavities. Length: 
6-7.5 mm. 
Male: Last ventral segment depressed at middle of apex; last 
dorsal segment broadly rounded at apex; posterior femora below with 
two teeth and behind the posterior one an oblique serrate ridge, the 
anterior tooth generally very small and occasionally absent; posterior 
tibiae not serrulate internally. 
Female: Last ventral segment rounded at apex ; last dorsal segment 
slightly narrower and a little longer, rounded at apex; posterior femora 
below with one tooth and behind with a rather indistinct ridge, Avhich 
is often scarcely visible even from an internal view.

This is one of the earlier species found from the middle to the end of 
May on the leaves of the yellow water lily. 
D. caerulea is made a synonym of palmata but the description, size 
and figure do not agree with the latter species. It is apparently the 
same as episcopalis Lac. which is wrongly considered to be a synonym of 
proxima. Lacordaire's description of episcopalis is very good and I have 
long hesitated to place it as a synonym of the more poorly described 
caerulea, but there is no other North American Donacia which would 
agree better with Olivier's description. Certain specimens with reduced 
femoral armature are apt to be mistaken for texana var. minor but 
caerulea is a slightly more robust insect with wider prothorax, shorter 
antennae and shorter hind femora and tarsi. In the material returned 
earlier this species is labelled proxima episcopalis. 
Donacia magnifica Leconte. 
Moderately elongate, depressed; color of upper surface shining and 
generally purple with sutural, lateral and apical margins and sides of 
prothorax metallic green, occasionally entirely metallic green with a
