Paracalocoris heidemanni Reuter, O. M. Bemerkungen uber nearktische 

 Capsiden nebst beschreibung neuer Arten. Acta Societatis Scientearum Fennicae, 

 36, No. 2, 1909, p. 40. (Aurora, W. Va., August 19, 1904,* O. Heidemann). 



Length 6-7 mm.; length of thorax 1.23-1.3 mm.; width of thorax; 

 front .66-.73mm. ; back 1.8-193 mm. ; length of antennal joints: first 

 1-1.16 mm., second 1.93-2.06 mm., third .9-.93mm., fourth .96-1.06 mm. 



Range: The known range comprises only Maryland, 

 Virginia and West Virginia. 



Two color varieties may be distinguished as follows: 

 A. Vitta overlying cubital vein contrasting decidedly in color with adjacent 



parts of corium var. heidemanni Reuter. 



AA. Corium practically uniform in color var. ablutus n. var. 



Paracalocoris heidemanni var. heidemanni Reuter. (Loc. cit.) 



The form described below must be regarded as the typical 

 variety, although Reuter's description of the ground color of 

 hemelytra as fusco-testaceous or isabelline, by no means 

 suggests the rich mahogany-red color of most of the specimens. 



Fully colored specimens are as follows: Head reddish testaceous, 

 with herring bone pattern on vertex in a darker red brown; eyes piceous. 

 Antennae dark red-brown, first joint sprinkled with yellow, and as a 

 whole with the following piceous markings: Extreme apex of first 

 joint, narrow basal annulus and apical half of second; apical 4-5 of 

 third and fourth joints. 



Ground color of upper parts a rich mahogany red, deepest on corium, 

 with the following yellow or golden markings; thorax anterior to apical 

 stricture, a median vitta and two others just outside discal spots extend- 

 ing to and broadening at posterior margin of thorax; narrow median 

 and broader marginal vittas on scutellum; streak on corium, bordering 

 basal half of clavus, clavus along commissure, vitta along cubitus to 

 apex of corium, narrow costal margin and sometimes a small isolated 

 spot at center of apical margin of corium. Cuneus somewhat deeper in 

 hue than ground color of corium. Membrane dusky, with paler areas 

 and pale reddish vein. Legs pale reddish, femora yellow spotted. 

 Under surface marked with yellow and mahogany red; a series of two 

 dark and three light stripes along side of thorax and about three dark 

 and four light, interrupted vittse on sides of body segments. 



In the paler specimens that may be said to have cubital vittse, the 

 ground color is yellow-brown to which the cuneus retaining its reddish 

 cast is in distinct contrast.
