This differs from the typical variety chiefly in the general paleness 

 of the ground color, which so approximates that of the vittae that 

 the latter are scarcely or not distinguishable, especially those on 

 hemelytra. The scutellar and thoracic markings usually are evident. 

 The cuneus is paler than in typical form though still in contrast (pale 

 reddish-brown) to groimd color (light orange-yellow). _ Upper surface 

 with abundant golden hairs as in typical variety. Vein of membrane 

 whitish.

Hypericum prolificum L. is the true food plant of Paracalo- 

 coris heidemanni in the vicinity of Washington, D. C, for upon 

 it the nymphs are reared. Occurrence of the species is practi- 

 cally restricted to the flowering season of the p. ant. 



The nymphs in my possession may be described as follows: 



Total length 4 mm.; length of thorax, .86 mm., width of thorax, 

 front .83 mm., back 1.6 mm.; distance from back of thorax to tip of 

 wing pad 1.53 mm.; length of antennal joints, first .83 mm., second 

 1.46 mm., third .83 mm., fourth .8 mm. 



Head and thorax sordid testaceous irrorated with reddish. First 

 two joints of antenna rufo-fuscous with abundant coarse black pile. 

 (Only the first joint is so haired in adult). First joint sometimes dotted 

 with yellowish. Third fuscous, pale reddish at base; fourth testaceous 

 to fuscous. Wing-pads sordid rufo-testaceous, these and remainder 

 of upper surface with numerous soft white hairs. Dorsum of abdornen 

 either reddish with a row of yellow dots across each segment, or yellowish 

 with red dots. Legs reddish to fuscous, femora spotted with yellowish. 

 Under surface reddish with yellow spots or the reverse.
