HUNGERFORD: AQUATIC HEMIPTERA. 57 
broad, flat lobes, with a little hump at the outer corner; surface finely 
pubescent, closely, finely, obsoletely punctate; with a dull black spot on the 
disk of the anterior lobe, which sometimes runs back narrower to the 
base, and on each humeral angle a black spot. Antepectus sand-yellow, 
but generally with the middle line of the sternum black; mesosternum, 
excepting its lateral lobes and posterior margin, black; metasternum 
also black. Legs sand-yellow, the coxe more or less black, as also the 
apex of the tibia, and a band on the tips of the second and third tarsal 
joints; nails generally testaceous. Scutellum black, minutely punctate, 
finely pubescent, arcuately impressed before the middle and with a slight 
elevated hump each side, usually carrying a yellow spot; the apex acute 
broadly yellow, or with two yellow, approximate spots, the lateral edges 
sometimes yellow. Corium sand-yellow, or whitish and yellow, minutely 
punctate and pubescent, marked with black or fuscous in very varying 
proportions, generally with a double black spot on the costal area before 
the middle, a similar spot behind the middle, and a smaller rounded one 
at tip; disk next the clavus and the clavus fuscous or blackish, the latter 
sometimes with a small yellow spot near the inner posterior angle, the 
former very often with a large yellow spot in the middle of the posterior 
margin, and often the margin itself yellow; membrane sand-yellow, some- 
times clouded with fuscous, and with a short transverse black band at 
base, the nervures piceous, long, and nearly straight. Venter pale yellow, 
finely pubescent, more or less blackish at base, and streaked on the disks 
of the segments each side, and sometimes with a row of black points a 
little way from the lateral margin; the genital segments and ovipositor 
more or less blackish. The spots on the costal area are frequently want- 
ing, or have only traces present; occasionally the tip of the slender 
cuneus is black. Generally the whitish spots at the apex of the discoidal 
_area of the corium are present and very conspicuous. 
“Length to tip of venter 5-6 millimeters; to tip of membrane 6-7% 
millimeters. Width of base of pronotum 214-3 millimeters. 
“First obtained in Cuba; afterward in Sonora, Mexico; since then on 
the sea coasts of Massachusetts, North Carolina and Georgia. I have 
met with it in large numbers on the sea coast of Worcester county, in 
Maryland, in July and August. It lives on the pale sands not remote from 
the beach, and the darker varieties may be met with running briskly 
over the gray or blackish sandy mud, neglecting the dry spots, but often 
swarming upon the moist places. 
“The genital segment of the male has a long, curved, acutely tapering 
appendage, and two shorter and straighter approximate ones in the 
middle, superiorly.”—Uhler. 
In the matter of distribution, Van Duzee adds New Jersey, Florida, 
Texas and California. ry 
Parsfley adds New Hampshire.

Acanthia hirta Say, Heteropt. New Harmony, 34, No. 2. 
“Brownish, darker before. Body densely hairy, dull yellowish-brown or 
fuliginous; head a little darker at base; thorax blackish before the trans- 
verse line. Scutel blackish. Hemelytra conspicuously hairy, with dull 
yellowish spots, as well on the membrane as on the corium. Pectus a 
little varied, with the remaining inferior surface, including the feet, 
immaculate. 
“Length to tip of hemelytra under one-fourth of an inch. 
“This species may be recognized by its more obviously hairy vesture; 
its color is also paler than usual in this genus. Inhabits Indiana.”—Uhler. 
To Indiana, Van Duzee adds Quebec, Connecticut, New York, New 
Jersey, Florida and Texas.
