Paracalocoris scrupeus Say. This species is commonly associated 

 with invitus on wild grape, and during some seasons large numbers 

 of the nymphs may be observed feeding on the tender leaves and 

 blossom clusters of this plant. The injuries to grape blossoms and 

 to the foliage are identical with both insects. The nymphs of 

 scrupeus are readily distinguished from those of the foregoing species 

 by the brownish bands on the antennae and legs. 



The nymphs of the third instar are slender, much like the young forms of invitus 

 in shape and size. The thorax is more rectangular and the appendages are more 

 slender. The antennae are long and filiform. Color, pale green; abdomen concolorous 

 with a median fuscous spot at the cephalad margin of segment IV. Eyes brown; 

 anterior angles of pro thorax fuscous; head and wing pads slightly suffused. Antennal 

 article I, the distal half of article II, and the distal third of article III fuscous; the 

 terminal joint is slightly suffused. Legs I, slightly suffused at distal end of femora; 

 tibia with narrow fuscous bands near proximal end, slightly suffused at distal margin; 

 distal tarsi deeply suffused. Legs II with similar markings more clearly defined. 

 Legs III have in addition to these areas a median tibial fuscous band. Body thickly 

 clothed with brown hairs. 



In the succeeding stages the changes which occur are chiefly in the size, growth of 

 the wing pads, and in the distinctness of the markings. The terminal antennal seg- 

 ment is much finer and nearly translucent. Legs II have a less distinct median tibial 

 band. 



Adult. — Body black; head with a dull yellowish line and superior orbits, variegated 

 at the mouth and beneath: antennas, first joint more than half the length of the second, 

 and rather robust, hairy; second joint a little thicker at tip: thorax yellowish, anterior 

 margin, two dots, and a slight dot near the posterior angles black; scutel yellowish, 

 dusky on the middle of the base and on the basal angles: hemelytra immaculate: feet 

 with minute pale points. Length to tip of hemelytra nearly one-fourth inch. 27 



A number of varieties of the adults transformed in the breeding cages. One of these 

 has the thorax and scutel pale yellow; on another the thorax and scutel are bright 

 orange; a third is fuscous in color with the median of the scutel bright orange-red for 

 two-thirds of its length.
