In small bowl, combine 1/4 cup bread crumbs, mayonnaise, onion, Dijon, lemon juice, Worcestershire sauce and parsley; mix well. Stir in crabmeat.
Unroll crescent dough; separate into 4 rectangles. Firmly press perforations to seal. Brush rectangles with melted butter (saving some melted butter for later); sprinkle each with 11/2 teaspoons bread crumbs.
To make each roll, spoon 1/4 cup crab mixture on 1 short end of each rectangle, spreading mixture onto 1/3 of rectangle. Starting with crab-filled side, roll up, just covering crab. Spoon 1 tablespoon red pepper next to edge of crab mixture. Roll up completely; press seam to seal. (Refrigerate remaining crab mixture for later.)
In shallow dish, stir together 1/4 cup bread crumbs, sesame seeds and black sesame seeds. Brush outsides of rolls with melted butter; roll in sesame seed mixture. Wrap each roll in plastic wrap. Refrigerate 1 hour.
Preheat oven to 375 degrees. Using serrated knife, cut each roll into 6 slices. Press cut side of each slice into remaining 1/4 cup bread crumbs. Place each slice, crumb side down, in each of 24 ungreased regular-size muffin cups. Spoon 1/4 teaspoon reserved crab mixture onto each slice; drizzle with remaining butter.
Bake 12 to 17 minutes or until golden brown. Cool in pan on cooling rack 5 minutes.
