Skithra
From Tardis Wiki, the free Doctor Who reference
The Skithra were a species of scorpion-like beings. At least one individual, the Queen of the Skithra, had a partly humanoid appearance.
The Skithra would steal the technology of other races and use it for themselves. Races that the Skithra are known to have stolen from include the Silurians, Thassor, Venusians, Klendov, and Dullirians.
The Skithra Queen threatened the Earth with a stolen Venusian spaceship with a Klendov warp drive and a Dullirian resonator. (TV: Nikola Tesla's Night of Terror)
