This species lias the general facies of though less widened 
jiosteriorly, but it is iniich larger and differs in color of antennae, 
joints of pronotal carinae, genital segments and other points. 
I have named it in honor of Mr. Chas. Dur)-, who has so gen- 
erouslj’ placed his material in this family at 1113- disposal.

Aradus lobatus Say. Heterop. Hem. (1831.) Coll. Writ. I. 354. 
/irachy) hyuchns lobalm Sziy. Stal. Emim. Hem. III. 145. 
Ivlongate, oval. Black, the pronotum lobate with acute 
emargination on lateral border and production of anterior angle. 
Length, male, 7.5 mni-8 mm. 
Head as wide as long, anterior process truncate, not incised; antennae 
slender, joint three longest, one, two and four about equal length, each 
about two-thirds of three. 
Pronotum as wide as base of abdomen, the lateral margin acutely emar- 
ginate which, with the projection of the anterior angles, give it a distinctly 
lobate form; disk coarseU’ granulate with four distinct elevated ridges on the 
anterior half. 
Originally described from Indiana, this species seems to be 
rather rare in collections, and in some ca.ses specimens of 
tns have stood under its name. It is much larger than that spe- 
cies, as stated by’ vSa>’, and the deeply indented margin of prono- 
tum .separates from any of the other species. I have a specimen 
from Florida collected by j\Irs. Slosson, and Mr. Dury has sent 
me an example collected at Cincinnati — both males. Bergroth 
cites its occurrence in Canada, Penn., Md., Mich., Ind., 111 ., 
Mo., Texas and California.

lUongate ovate ; black. Surface finely granulate, elytra white. 
Length, male, 4.5-5 mm.; female, 6 mm. 
Head about as broad as long, antennae slender, third joint slightly longer 
than the others, which are about equal. 
Pronotum trapezodial, the lateral margins sloping towards the head from 
the basal third, surface granulate, without trace of elevated carinae. .-\bdo- 
men very flat. Elytra occupying about one-third of dorsal surface. 
Color dark brown or black throughout, except elvtral membrane, which 
is white, though sometimes infuscated on central part, and disk of abdomen 
under the elytra, which is red. Some .specimens are less intensely black 
than the others, but excej)t in immature individvals such cases are rare. 
This .seems to be our most abimdaut species, having been taken 
ill large numbers at different points in the State, Columbus, Cin- 
cinnati, Williamsburg and Hanging Rock.
