HUNGERFORD: AQUATIC HEMIPTERA. 133 
and tibiz, small in size (2 lines long). The three last antennal seg- 
“ments very small compared to the first, a character belonging also to the 
previous species (V. rivulorum). The examples are completely developed, 
having three segmented tarsi and thus can not be larve.” 
“Champion, who examined one of Burmeister’s types, says that seg- 
‘ments 2 and 3 of the intermediate tarsi are equal in length and that the 
eyes do not reach the front of the pronotum.” 
Reported now from Pennsylvania, District of Columbia, North Caro- 
lina, as well as West Indies.

“Winged form. Moderately elongate, brownish-fulvous or brownish- 
testaceous, the posterior half of the pronotum fuscous; the venter and 
pleura more or less fuscous, and grayish-pruinose; the antennz testa- 
ceous or brown, with the second joint darker at the base and apex; the 
legs flavous, annulated with fuscous; the coxe and trochanters flavous; 
the elytra blackish-brown, with a long silvery-white streak at the base 
and three white spots at the apex—the inner one lunate, the others 
rounded; the body, legs, and antennz very finely pubescent, and also 
thickly clothed with long, fine, pallid hairs; the pleura, a spot at the sides 
of each of the ventral segments, a triangular mark on each side of the 
-pronotum anteriorly, and a spot on both the anterior and posterior sides 
of each of the femora towards the base, clothed with short silvery pubes- 
cence. Head with a smooth, faintly impressed median line; the eyes large 
and coarsely faceted, reaching the anterior margin of the pronotum; the 
antennz long and slender, joint 1 stouter, and fully one-half longer than 
2, 2-4 subequal in length, 3 and 4 very slender. Pronotum distinctly 
punctured, rounded at the apex behind; the junction between the an- 
terior and posterior lobes indicated by four transversely placed punc- 
‘tures and a triangular lateral depression. Legs comparatively stout, 
‘rather short; the intermediate tarsi with joint 2 much longer than 3; 
posterior femora and trochanters very minutely denticulate on their 
inner edge in the male, and faintly so in the female. 
“Male. Sixth ventral segment deeply arcuate-emarginate at the apex. 
“Apterous form. Pronotum abbreviated and subtruncate behind; the 
elytra sometimes represented by a pair of small white wing-pads; the 
dorsal surface of the abdomen fuscous, the terminal two or three seg- 
‘ments more or less clothed with glistening silvery pubescence. 
> “Length, 4-5; breadth (of the pronotum in the winged form), 1% mm. 
. Male and female.”
