Story on the back:

"The Martians landed and inspected the damage that they had done. Streets were beyond recognition and mighty cities had been all but leveled. Bodies lay on the streets, unfortunate victims of the Martian destruction. By some means the aliens had found a way to communicate with the giant insects that they had created. The bugs followed any instructions given to them from the spacemen. The Martians ordered the creatures to remove the bodies from the streets. Flying insects flew off with several bodies in their claws at a time. The aliens wanted all the streets clear before the people of Mars were brought to Earth to establish a new Martian domain."
