This species has the general iaciesoi (//(zri though less widened 

 posteriorly, but it is much 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. Dury, who has so gen- 

 erously placed his material in this family at my disposal. 



Brachyrhynchus lobatUvS, Say. 



Aiiidits lohatus Say. Heterop. Hem. (1831.) Coll. Writ. I, 334. 

 Brachyi hynrkits lohaiiis Say . Stal. Enutn. Hem. Ill, 145. 



Elongate, oval. Black, the pronotum lobate with acute 

 emargination on lateral border and production of anterior angle. 

 Length, male, 7.5 mm-8 mm. 



Head as wide as long, anterior process truncate, not inci.sed ; 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 forju; disk coarsely 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 cases specimens of gra/iii/a- 

 fiis have stood under its name. It is much larger than that .spe- 

 cies, as stated by Say, and the deeply indented margin of prono- 

 tum .separates from any of the other species. I have a specimen 

 from Florida collected by Mrs. 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.

 State .\cad. Sci. VIII, p. 77 (record only). 



Elongate ovate ; black. Surface finely granulate, elytra while. 

 Length, male, 4.5-5 nun.; female, 6 mm. 



Head aljotit as broad as long, antennae slender, third joint slightly longer 

 than the others, which are about equal. 



Pronotum trape/.odial, the lateral margins sloping towards the head from 

 the basal third, surface granulate, without trace of elevated carinae. Abdo- 

 men very flat. Elytra occupying about one-third of donsal surface. 



Color dark brown or black throughout, except eh-tral membrane, which 

 is white, though sometimes infuscated on central part, and disk of abdomen 

 under the elytra, which is red. Some sjjecimens are less intensely black 

 than the others, but exce])t in immature iudividvals such cases are rare. 



This seems to be our most abundant .species, having been taken 

 in large numbers at different ])oints in the State, Columbus, Cin- 

 cinnati, Williamsburg and Hanging Rock.
