CentralAmerica, and enters into the United States at the south, being foundin Texas and Florida. Specimens have been seen from Cuba, PortoRico, and St. Croix (U. S. Virgin Islands) in the Lesser Antilles. 1 In individuals of this form examined by the. writer flic general color of the dorsal surface of the abdomenis much darker than Morrills (7) figure would indicate. 12 BULLETIN 689, U. S, DEPARTMENT OF Fig. 12.—Map showing distribution of the Southern green plant-buglathe United States. Shaded areas indicates probable distribution. In the United States (fig. 12) its range covers the extreme southernportion, although at times it occurs outside this area. In the files ofthe Bureau of Entomology there are records of its injurious occur-rence in South Carolina, Georgia, Florida, Alabama, Mississippi, Louisiana, and would indicatethat the species ismost numerous in thesouthern portion ofthe Cotton Belt. From what hasbeen observed in re-gard to the distribu-tion of this species, itis evident that it is offoreign origin and, likemany others of ourprincipal pests, wasintroduced into this comitry many years ago. It is also obviousthat it would be impossible even to hazard a conjecture as to thesource from which it obtained a foothold in the southern UnitedStates. REVIEW OF LITERATURE. The species was first described as Cimcx vir
