A PECULIARLY MARKED ADULT OF NEZARA VIRIDULA L. (HEMEP.). 



BY THOS. H. JONES, U. S. Bureau of Entomology. 



While making a collection of adults of the southern green 

 plant-bug (Nezara viridula L.) at Baton Rouge, La., August "2(\, 

 1919, Mr. C. F. LaGrone took two abnormal individuals. Mr. 

 LaGrone has called my attention to these individuals and, es- 

 pecially since one shows such a marked difference in coloration 

 from the typical green specimens of the species, I have thought 

 it advisable to present the following note concerning them. 



Both individuals are females and were collected on beans. One, 

 while generally of the normal green color, has light areas, so 

 outlined as to give bilateral symmetry of markings, on the dorsal 

 surface of the head, upon the pronotum, and upon the heme- 

 lytra. These are indicated in Fig. 1. When the adult was 

 alive these areas were white but in the mounted specimens took 

 on a yellowish tinge. 



Fig. i Nezara viridula. 



A light colored area covers about one-half of the dorsal sur- 

 face of the head and includes all that portion anterior to a V-- 

 shaped line whose ends are opposite the middle of the inner mar- 

 gins of the compound eyes, and whose middle is on the tylus 

 somewhat anterior to the beginning of the sutures between it
