"Length to tip of venter 3 mm. 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-w^inged in the month of June. The male 

 is narrower and more wedge-shaped posteriorly than the female."

Microvelia signata Uhl. 



Uhler, Proe. 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; antennae russet- 

 brown, paler, towards the tip, the joints long; rostrum dull testaceous, 

 dark at tip, reaching behind the anterior coxje. 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, m.arked vdth 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.

"This beautiful little species was taken at San Esteban, in April, by 

 Mr. Charles D. Haines."

Microvelia robusta Uhl. 



Uhler, Proc. Zool. Soc. 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 antennae 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.)"
