Saute the scallions, garlic, and parsley in a tablespoon of melted butter over medium heat until wilted.
In a large mixing bowl, combine the eggs, worcestershire sauce, dijon mustard, salt, pepper, 1/2 cup cracker crumbs, grated parmesan, and mayonnaise. Fold in the crabmeat. Shape into 8 crab cakes and coat in remaining cracker crumbs. Place crab cakes on a buttered baking pan. Melt butter and mix with lemon juice. Drizzle 1/2 of lemon butter over crab cakes.
Bake for 20 minutes at 350 degrees. Drizzle remaining lemon butter over crab cakes and broil for 2 minutes until slightly browned.
