In a large pot over medium heat, melt butter; stir in flour and cook until bubbly. Stir in green onions, chopped onion, bell pepper, celery, garlic, bay leaf, thyme, and basil. Reduce heat to low and cook, uncovered, stirring often for approximately 20 to 30 minutes or until vegetables are soft.
Increase heat to high and add tomato sauce, wine, clam juice, water, worcestershire sauce, white pepper, and Tabasco; stirring, bring to a boil. Reduce heat to low and simmer, stirring occasionally, about 45 minutes or until thickened and reduced to 4 1/2 cups. Stir in lemon zest, lemon juice, parsley, and shrimp. Simmer approximately 2 to 3 minutes or until shrimp are cooked. Remove from heat and serve over hot cooked rice.
