Il6 BROOKLYN MUSEUM SCIENCE BULLETIN 3. 3. 
not prominent, small, separated from the disk by a rather broad, oblique 
impression; transverse apical impression moderate, limited behind by an 
oblique, obtuse ridge; median impression fine; ante-basal impression 
faint; surface densely and finely rugose, scarcely shining, except at base 
above the scutellum, where the sculpture is rather strigate. 
Elytra about two and one half times as wide as the prothorax at 
base; sides almost parallel, feebly narrowing to about apical fourth, 
thence more strongly arcuate towards apices, the latter truncate, with 
the outer angle rounded; strial punctures rather large, gradually smaller 
towards apex; surface rather coarsely and densely rugose, the ante- 
median and post-median impressions absent or exceedingly faint. 
Body beneath densely finely punctate, pubescence pale yellowish, 
short and rather close but permitting the punctuation and surface color 
to be seen; the usual pubescent space near the anterior coxae is faint 
and scarcely visible; the intercoxal process of the mesosternum is peculiar 
in being triangular, but possibly accidental; posterior femora extending 
slightly beyond the apex of the fourth ventral segment, rather robust and 
feebly clavate, unarmed below; last ventral and dorsal segments broadly 
rounded at apex. Length: 8 mm. 
Florida. 
Male (Allotype) : Color as in the female but only the last three 
ventral segments reddish; it differs from that sex in being smaller and 
less robust, with longer antennae which reach to about the middle of 
elytra; the prothorax is more distinctly converging towards base; the 
last dorsal segment is broadly rounded at apex; the last ventral segment 
truncate at apex with scarcely a trace of the usual median impression; 
the mesosternal process is moderate and not quite half as wide at middle 
as the middle coxal cavities; the posterior femora are armed below with 
a moderate, acute tooth. Length: 5.75 mm. 
Dunedin, Florida (April 16). 
The female I owe to the kindness of Mr. Charles Liebeck; the male 
was collected by Prof. Blatchley and remains in his collection. 
This is a peculiar species, the female can scarcely be compared in 
form with any Donacia known to me, the male looks somewhat like 
Juhipes. 
The triangular or subtriangular mesosternal intercoxal process of 
the female is possibly accidental as it is apparently normal in the male, 
though somewhat obscured by the dense pubescence.
