Skeleton Gang
From superman.nu: Supermanica
The Skeleton Gang
An organization of thugs and former members of Skull who terrorize Metropolis with a wave of crime. In order to expose the villainous actions of the gang, Superman asks Lois Lane to operate undercover as an evil agent partially responsible for his fictitious loss of sight - an action of trust in Lois that makes a jealous Lana Lang angry enough to leave the city (S No. 334, Apr 1979: "The Man Who Stole Superman's Eyes!").
