SOUTHERN GREEX PLANT-BUG. 



11 



Thorax: For most part dark brown, nearly black. Black-bordered, orange-colored 

 areas, one near both outside edges of prothorax and one near outside edge of both 

 primary wing-pads. Yellowish area along inside edge of both primary wing-pads. 



Abdomen: Dark brown, almost black. 1 At base a yellowish-white area on either 

 side of median line. Other yellowish-white spots and rose-colored areas on connexi- 

 vum as in light form. 



Ventral surface. 



Head: Olive green with black markings. Beak and antennae olive green to black, 

 lightest near base . 



Thorax: Olive green with black markings except for chrome-orange areas near edge 

 of prothorax and mesothorax. Legs olive green near base, becoming gradually darker 

 to black tarsi. 



Abdomen: Light yellow tinged with red and with black-bordered, rose-colored areas 

 on connexivum corresponding to those on dorsal surface. Row of four greenish-black 

 spots along median line. Spiracles black. 



COMPARATIVE LENGTHS OF ANTENNAL SEGMENTS OF NYMPHS AND ADULT. 



While the measurements given in the following table are taken 

 from single individuals only, they indicate the comparative lengths 

 of the segments in any one stage. It will be noted that the antenna 

 of the nymph is made up of four segments while that of the adult is 

 composed of five. In this connection it may be stated that the 

 writer has seen an abnormal adult with one antenna composed of 

 four segments and the other of five. 



Up to and including the third instar the fourth segment of the 

 antenna is longest. In the fourth and fifth instars the second seg- 

 ment is longest, while in the case of the adult the last three segments 

 are of about equal length, any one being longer than either the first 

 or the second segment.

DISTRIBUTION. 



Bueno (9) states that Nezara viridula is recorded ''from the whole 

 of Europe except the extreme north, Asia, Africa, Malaysia, Aus- 

 tralia, New Zealand, South America, at least in the north, Central 

 America, and enters into the United States at the south, being found 

 in Texas and Florida. " Specimens have been seen from Cuba, Porto 

 Rico, and St. Croix (U. S. Virgin Islands) in the Lesser Antilles. 



1 In individuals of this form examined by the writer the general color of the dorsal surface of the abdomen 

 is much darker than Morrill's (7) figure would indicate.
