and forming sharp anterior angles beyond the eyes; posteriorly abruptly 

 rounding into flaps, which are, in clear specimens, of a strikingly paler 

 color than the other part of pronotum ; the edges armed with irregular 

 teeth, which suddenly change into diminutive ones near the humeri ; 

 disk of pronotum carrying the usual six longitudinal carinate lines, the 

 inner ones nearing each other, the outer ones much abbreviated ; the cal 

 losities very feebly defined. Scutellum tumidly elevated across the mid 

 dle near the base, the sides slightly rounded and sharply edged, and pale 

 at tip. Hemelytra moderately expanded near the base and narrowing 

 considerably to\\wds the membrane; corium pale, darker between the 

 cross-veins and blackish at base and apex. Abdomen of the female elon- 

 gatel v-rounded, cinnamon-brown above and below, the outer margin of 

 the connexivum darker, at the incisures pale, intermixed with patches of

 darker in color, except the ventral part of the last two segments, which 

 are -pale. The membrane reaches the fifth or base of the sixth abdominal 

 segment; in the male the membrane extends to the end of the abdomen. 

 Feet finely granulated and dark brown, the coxae and the tip of femora 

 and tibiae paler. First genital segment of the female nearly half as long 

 as the sixth abdominal segment; genital lobes broad, truncate at apex,

This species ought to be placed next to A. similis Say, with 

 which it has the most resemblance. It differs from that species, 

 however, in the form of the thorax and especially in the shape of 

 the female genital lobes. A. similis Say has the sides of the 

 thorax more or less rounded, the surface flat, with the callosities 

 prominent, and the female genital lobes decidedly emarginated. 

 A. hubbardi is also related to A. debilis Uhl., from which it 

 can be at once distinguished by the shorter and thicker antennas 

 and in having the abdomen of the female less narrowed towards 

 the apex. 



I have named this species in honor of the late Mr. H. G. Hub- 

 bard, the eminent American entomologist, who has made valuable 

 observations on the habits and life history of hemipterous insects, 

 and by his extensive collections has added greatly to our know 

 ledge of the Hemiptera fauna of the United States,
