strial punctures, shining and feebly rugose on the disk, at sides and 
apex distinctly and somewhat strigate-rugose ; apex truncate, outer 
angle more or less distinct but obtuse and feebly rounded. 
Body beneath very finely and densely punctate and very densely 
pubescent with fine, short, silken hairs ; side pieces of prosternum with a 
rather large, densely pubescent space near anterior coxae; mesosternal 
process between the middle coxae as wide or nearly as wide as the coxal 
cavities; middle tibiae normal. Length: 8-9.5 inm. 
Male: Last ventral segment sub-truncate at apex with a distinct 
apical depression at middle; last dorsal sub-truncate at apex; posterior 
femora extending beyond the apices of elytra, moderately strongly 
clavate in about apical half, anterior half very narrow; armed below 
with a rather small, acute tooth; tarsi normal, slender. 
Female: Last ventral segment arcuately narrowing into an obtuse 
point; last dorsal elongate, sub-triangular; posterior femora as in the 
male, but shorter and extending to the apex of the fourth segment.

Donacia texana is a distinct species and not a synonym of hypoleuca. 
The head and prothorax in texana are very much like those of palmata 
and differ in this respect from hypoleuca of which the male has the 
anterior and middle tarsi shorter and stouter than those of texana. 
A slightly smaller form occurs rather abundantly further north 
which deserves a separate name, 
var. MINOR new variety. 
Differs from typical texana in smaller size and relatively larger 
strial punctures of elytra. Length: 6-7.25 mm.
