2 25 to 3.20. This species israther rare. It begins to be met with about the middle 
of July and continues until the arrival of cold weather. 
Mr. Stephens has also described a species under this same name. Mr. Say, how¬ 
ever, appropriated the name to our insect more than ten years anterior to its use by 
Mr, Stephens. Another name therefore becomes necessary for the British species, 
which, if it has not already been re-named should bo designated the Stephensn, in 
honor of its first describer, the eminent entomologist recently deceased. 
Mr. Say in connection with the preceding (in the appendix to Long's Expedition, 
page 306) describes another species, the vittalus or Striped lace-wing, from a speci¬ 
men in the Philadelphia museum, found by Mr. Titian Peale, in New Jeisey. This 
is of the same size with the Freckled lace-wing and closely resembles it, but has the 
body of a pale yellowish color with a broad blackish stripe upon each side of the 
thorax, and a small white spot on the outer edge of the fore wings near the tip. I 
have never met with this, which appears to be a rare species. 
The Alternated lace-wino (H. alternate) is dull whitish or yellowish white 
varied with dark brown, and is clothed with short pale yellowish hairs. Its face and 
a stripe on each side of the thorax is blackish brown. The abdomen is dull whitish 
with a clearer white stripe aloDg each side, which is margined above by a row of 
spots and below by a slender line of a brown color. The wings are pellucid and iride¬ 
scent red and green; the veins are white with alternating blackish spots givmg ofi 
fine bristles of the same color. The veinlcts are black, robust, and broadly margined 
with smoky, forming two irregular rows of spots across the wing, with a third short 
one between them upon the inner margin. The margin is whitish, with dusky spots 
of different sizes, the larger spots having two or sometimes only one smaller spot be¬ 
tween them. The hind wings are pellucid, their veins white, those next to the rib- 
vein with dusky spots, the veinlets blackish but not margined with smoky; the inner 
fork of the innermost longitudinal vein is also blackish from the anastomosing veinlct 
half way to the furcation. The margin of these wings is whitish alternating with 
dusky spots around the apex. A dot or short line is placed ou the margin between 
the tips of all the vein’s and their forks. The wings expand 0.80. This occurs the 
last of June, particularly upon pine and hemlock bushes. 
The Stioma-marked lace-wino (H. stigmaterus) has the veins of the fore wings 
black with white bands; the cells are smoky with clearer spots at each of the white 
bands-upon the veins; stigum opake tawny reddish; two series of black anastomos¬ 
ing veinlets; a third veiulet near the inner base connecting the first longitudinal vein 
with the inner fork of the second longitudinal, and on the opposite side continued to 
a branch of the first longitudinal, thus forming two closed basal cells, the outer one 
of which is long and narrow, with the second longitudinal vein forking near the mid¬ 
dle of this cell. This last mentioned veinlet is more robust and more obviously 
margined with dusky than the others. Head and antennas pale dull yellow; legs 
paler; thorax and abdomen blackish brown. A variety which is common has the 
tip of the abdomen pale yellow, and another variety has a pale stripe along each side 
of the abdomen. The wings expand from 0.65 to 0.60. This is a common species 
throughout the Northern and Western States, occurring from March until October, 
resting upon the foliage of various evergreen and deciduous trees and upon the grass
