“Length to tip of venter 3mm. Width of pronotum, 1.25 mm. This is 
a common species in Maryland, and is also found in North Carolina. It 
has also been collected in Colorado, and in the vicinity of San Diego, Cal. 
In Maryland it occurs on the borders of small streams during summer, 
and is occasionally found full-winged in the month of June. The male 
is narrower and more wedge-shaped posteriorly than the female.”

Microvelia signata Uhl. 
Uhler, Proc. Calif. Acad. Sci. Ser., 2, vol. 4, p. 288. 
“This species has somewhat the form of M. modesta Uhler, but it is 
a longer and much more conspicuous insect; the color is a dark brown, 
with more or less bluish bloom, and minutely pubescent. Head short 
subconical, with a smooth grooved line on the middle; antenne russet- 
brown, paler towards the tip, the joints long; rostrum dull testaceous, 
dark at tip, reaching behind the anterior coxze. Pronotum moderately 
long, convex, feebly sinuated on the sides, the anterior submargin with 
a bright orange band which does not reach the sides; sternum and 
pleural segments dark plumbeous, bordered with testaceous. Legs pale 
testaceous, obscured above with fuscous and the tarsi more or less fuscous. 
Hemelytra velvety, long, and much narrower than the pronotum, clavus 
with a white streak, corium with a longer white streak at base which 
grows wider posteriorly, the membrane long, marked with one or two 
faint spots near base, with a clear long spot beyond and another longer 
near the tip. Venter dull yellow, brighter on the connexivum, and dusky 
along each side of disk. 
“Length to tip of venter, 3 mm. Width of pronotum, 1144 mm. 
“This beautiful little species was taken at San Esteban, in April, by 
Mr. Charles D. Haines.” 
Localities given in Van Duzee: California, Colorado and Mexico. 
Microvelia robusta Uhl. 
Uhler, Proc. Zool. Soe. London for 1894, p. 219. 
“Shorter and comparatively more robust than M. modesta. Colors 
about the same, except that there is an absence of pale color from the 
venter and no yellow border on the connexivum. The head is immersed 
nearly up to the eyes in the pronotum; the eyes are bordered internally 
with prostrate white pubescence; the front of the pronotum is shorter 
and less contracted, densely covered with white pubescence, which is laid 
upon a faintly yellow band; the pleural pieces are not broadly bordered 
with testaceous, and the posterior femora are only a little longer than 
the middle ones; the last joint of antennez more than one-third longer 
than the third joint. The hemelytra are smoke-brown, often pale, with 
two white diagonal streaks at base, pale spaces in the areoles, and a 
white pyriform spot in the apical areole; the costal area is almost linear, 
deflexed, pale, and marked with a row of remote brown dots. 
“Length to tip of venter 2 mm.; width of pronotum % mm. 
““A few specimens were collected at Woburn and Beaulieu, August 25, 
at an altitude of 700 feet above the sea, on the surface of a stagnant 
pond; another specimen was taken on the Mount Gay estate, in Septem- 
ber. (St. Vincent.) ”
