ADDITIONAL NOTE ON NEARCTIC ARADID^. 

 BY DR. E. BERGROTH. 



Having received further materials of North American Aradidae, 

 I find it necessary to add the following to my paper : 



i. Aradus concinnus n. sp. 



Subovatus, fusco albido et ferrugineo varius, pronoto lateribus denticu 

 late, scutello basin versus subpai-allelo. Long. $ 4.8 mm. 



Head dark, fuscous, a little longer than broad. Antenniferous spines 

 armed with a distinct tooth on their outer side. The tubercle near the 

 eyes very distinct. Antennae rather short and stout, dark fuscous; the 

 first and third joints, except the inmost base of the latter, are sordid yel 

 lowish, the second joint annulated with the same color immediately before 

 the middle ; the third and fourth joints are subequal in length, each almost 

 half as long as the second, which is gradually incrassated towards the tip. 

 Rostrum reaching the middle of the mesosternum. Thorax not quite 

 thrice as broad as long, narrower than the hemelytra at their dilated part, 

 light fuscous with a whitish patch at the antero-lateral margins, the sides 

 denticulated and obtusely angulated, the greatest width is in or im 

 mediately before the middle and from this point the sides are much 

 less converging towards the base than towards the apex, the antero- 

 lateral margins very slightly rounded, the postero-lateral margins 

 straight ; the disk bears six parallel fuscous keels, of which the outermost is 

 abbreviated in the usual way. Scutellum with the sides nearly parallel 

 from the base to the middle, then converging towards the apex, the disk 

 yellowish with the basal part to near the middle fuscous, the sides from a 

 little behind the middle to the tip margined with black. Breast ferru 

 ginous in the middle, acetabula whitish. Hemelytra in the male almost 

 reaching the apex of the abdomen, widened, rounded, and somewhat
