ANNUAL REPORT OF NEW-YORK 
say’s RKTEBOPTEROUS hemiptera. 
Ruduvius, Fabr. 
1. R. linitaris, Black, thoracic and abdominal margin, basal 
margin of the hemelytra, coxa: and pectoral spots sanguineous. 
Inhab. Indiana. 
Body black, somewhat hairy : thorax transversely impressed 
before the middle; a narrow sanguineous margin all around: 
scutel with a narrow sanguineous margin: hemelytra with the 
basal third of the costal edge dilating a little on the humerus, 
sanguineous: abdomen on the superior and inferior margin san¬ 
guineous : feet anterior pairs, trochanters and above each foot 
on the pectus, sanguineous; posterior tibiae slightly curved near 
the tip, and with a hairy dilation nearly equal to the diameter 
of the tibiae. 
Length to tip of hemelytra seven-tenths of an inch. 
Both this and the following species have many points of agree¬ 
ment with theFabrician description of crassipes, which however is 
“ fuscous“ thorax margine laterali et postico tenuissime rufo. 
Scutellum nigrum.” It is the anterior pairs of the tibiae that are 
robust and they exhibit on the anterior tip a groove to receive the 
tarsi. 
2. R. ventralis, Brown-black; posterior margin of the elytra, 
and abdomen sanguineous, the latter with lateral black spots 
and lateral vittaj beneath. 
Inhab. Missouri. 
Body brown-black, somewhat hairy: thorax transversely im¬ 
pressed before the middle; anterior portion inequal; posterior 
portion margined each side and behind narrowly with sanguine¬ 
ous : hemelytra with a rufous corium: abdomen sanguineous, 
with large marginal quadrate black spots above and beneath 
and dilated lateral black ventral vittm: coxa sanguineous: feet 
not remarkably distinguished. 
Length about two-fifths of an inch. 
The feet are not remarkably dilated as in crassipes F.: the 
species is also described to have "elytra fuscabasi parum rufa” 
“ corpus nigrum pectore utrinque punctis, abdomine margine 
rubris” “ pedes incrassati” <fcc. I owe it to the kindness of Nuttal. 
3. R. acuminatus, Yellow, dusky along the middle; head 
vesicular behind; hairy.
